Best Portable Screen

hey gracepoint sound peeps,

i'm looking to get a couple of new screens for us to use for venues like retreats, weddings, prayer meetings, etc...

we have a very nice 9x12 rear-projection but is a bit dull when you're pointing forward at it, unless it's right up against a wall. So i'm looking for forward-facing screen, fast-fold and....i'm not sure about the size.

i don't want a tripod style b/c at that size it's easy to break and too tall. also the one we use for side screens at willard is too tall as well and requires those separate stands, which we lost.

any thoughts on size and addl things to look for?

Countryman E6 on a Shure Wireless

here's question from our SF campus:

"We are using a Countryman for Matthew's wireless and he likes to pace back and forth as he talks. However, when he does this, the volume goes up when he turns left and down when he turns right. He wears his mic on the right ear. I am not sure if this is an issue I can improve by playing around with the gains on the wireless pack.

Do you think a DPA mic would be better or could solve the problem? (We currently don't own one.) Or a compressor? Matthew also likes to speak softly at times and then he raises his voice for added emphasis. I ended up having to play around with the volume turning the speaker up and down if he was too soft or too loud. Another factor was that I used the Countryman mic whereas the wireless pack was calibrated for the lapel mic, and I didn't adjust the gain. I was going to try just using the correct wireless pack that is calibrated for the Countryman mic next time to see if that improves the volume for Matthew.

Please let me know what you think from your experience. Thank you!"

Blue Flame Pro

Blue Flame Pro is a Bidirectional Media Converter that we use on Sunday's for our overflow setup.



Here are setup steps:
1. Connect output A YC (s-video) via s-video cable to projector
2. Connect output A CH1 and CH2 via XLRs to snake
3. Connect DV I/O via firewire cable to DVoverIP laptop

Once all the devices are powered on,
1. Turn on power of Blue Flame.
2. Turn on codec by clicking “ON POWER” button.
3. Start digital to analog decoding by clicking “DV DECODE” button.

Other things to know:
* Press the DV Decode Selector to do a RESET.
* Main Power Switch: Should the unit be powered off, allow 10 seconds for system reset before turning on power again.

Video Recording Directly to Computer

We video record some of our skits, messages, talks, etc.. for archiving purposes as well as for future training. The standard procedure for us has been:

1. record event to DV tape

2. capture/digitize DV tape with Final Cut Pro in real time.

3. edit and export FCP project into a smaller/portable format - like h.264

I've tried a new method recently.

1. record event to DV tape AND directly capture/encode with Quicktime Broadcaster.

* this way we have a backup of the event on tape and we have an already captured and compressed digital version.

* i haven't tried doing this with regular Quicktime and especially the new version of Quicktime with Snow Leopard which i hope to test soon.

I'm attaching some screenshots to help you to know what settings you should use. Main thing to note is that the resolution is small, the data rate is lower and audio quality is lower. This is a good and fast way to make video files available for others. It's not the highest quality but this is very, very fast and speeds up the whole process. I think we save around 3 hours that would normally go into setting up the capture station, capturing and then exporting. Below are some screen shots of the settings I use. For better audio quality you can do stereo instead of mono.

Sound Mixing

Wow, can't believe it's my first post on Gracepoint Sound! I wanted to learn how to mix well at our bible studies and Sunday Worship Services for some time now. But given the amount of time and people involve during our typical run through, it's very difficult to have a good understanding of how each frequency works on the mixer (I tend to just turn the knobs and hear what sounds best). So I started doing some research on how to mix well and the theory behind mixing online and I've stumbled onto a website that has a lot of good info on mixing and just church sound systems in general:

http://www.behindthemixer.com/

The website gives a lot of theory and different preference on how to mix and what to look out for. I've been playing around the EQ on my iTunes and car stereo and it's been great =) ! Hope this website is helpful for everyone and kudos to Chris who runs the site.

ProPresenter Dual Head Tutorial

In this short clip, learn the very basic and rudimentary way to setup ProPresenter for our Sunday Worship Service. Now one person can run the slides for both the main screens and the ones the singers use. Remember the main screen has words on a colored background or even picture while the background for the singers must be completely black. I'm very glad we were able to reduce our team by one person. =) Really, I much rather have more people in the actual service.

Black Box

I learned this term at a conference about training, raising leaders and growth. And it's a topic we've discussed among the leadership at our church as well. A black box is a mystery and it's something few can figure out. And when it comes to leaders of things like sound/tech, etc... this can be quite dangerous. It means that not enough people are learning and growing and possibly even control issues.

I've been thinking about this for myself a lot lately as one of the tech leads at our church. We've been training a lot of people in the past few years and that's really exciting. In fact, recently I've removed myself from the Koinonia Sound Team so that the students can do the setup and one of the junior guys is leading it all. But I think this is not enough. I cannot and should not be the limiting factor for growth and transfer knowledge. Being replaceable is a very important trait to have for growth.

So I'm trying to train up with even greater zeal and intensity the next generation so that I can be phased out. So the focus of many of my posts is going to be on process and ideas and systems we have in place and that we should.

Full Compass = Full Service

When we were first doing sound stuff at our church we were really the small time. Our first sound system, back in the late 80's was $1500 - for everything! Now, I think the quality was decent but over the years I've come to learn that you get what you pay for. Just to give you an idea of where we've come from: One of my great sound mentors - Pastor Jonathan, who is now leading Gracepoint Davis and taught me a lot - loved shopping at Radio Shack! Now, Radio Shack certainly has some useful and interesting gear for sure. But I think the flagship sound products is like Realistic - not to diss Pastor Jonathan too hard =).

Well, we've grown a lot since those first days and so have our needs. Our vendor of choice over the years has been Full Compass and our main sales contact is Kurt Krueger. Let me tell you that Kurt has been awesome for us over the years. He's given us great and competitive pricing and Full Compass has a huge selection of gear. Also, anytime we've had problems with our gear upon receipt Kurt has always been generous to swap it out right away for us. He'll send a new piece of gear before we even return ours. And their selection of gear is enormous - along with some great B-stock deals and other specials. And I can't tell you how many times Kurt has helped us out with shipping - when we needed something in a pinch or just to help with us with some of the costs. Recently, we needed a new Kramer switcher for our overflow needs and I also knew we needed one for our RISE event so I ordered one thinking it was in stock 1 week before RISE. But it turns out they didn't get it until a few days before RISE and the regular shipping wouldn't get it to me in time so Kurt upgraded me for free so I could get it on Friday - the day before RISE. I don't need to wonder why Kurt is part of the Million Dollar Sales Club. Thanks Kurt!

Of course, I think I could scour the internet and find better pricing on individual pieces of gear and such but most of those places are in NY - you know what i mean? =). And I realized that you don't just pay for gear but the service that backs it up. Sure I could save a few bucks here and there but I do believe you get what you pay for. And sometimes we get even more with Full Compass.

Is this a shameless plug? Well, Kurt didn't ask me to do this but I often get questions about where you get your gear from and I just like to let others know where we go. I don't think my post will give them a whole lot of business but I did want to give them a shout out!. But I wanted to let our church members that we try to go for quality. Especially as a church on wheels we need the roughest and toughest gear. On a tangent, I'm sure we can break any piece of gear. B/c we've broken about everything we've bought before. =)

My First Sunday with Pastor Ed Kang

Nope, this is not about my first time meeting Pastor Ed Kang. It's about my first time doing sound at the board with Pastor Ed. Now, I've been doing sound/tech stuff for church for about 10+ years and I've learned a lot but when I first started as I was as green as grass. I was running the board after only 1-2 months of training b/c the previous sound guy was going to LA for grad school and I had to fill his shoes.

And that first Sunday I was running the board we had some major feedback problems and mics not properly set. In particular, Pastor Ed's mic was not set with the right gain and so it gave out a loud and sharp feedback loop through the system causing everyone to wince...I remember Pastor Ed Kang saying with a smile, "Man, I miss Jeff..." and many roared into laughter. So my first Sunday running the board was with Pastor Ed and as much as I made that big mistake his funny comment helped relieve some of the pressure and stress. It's like another time when some of my peers and I were doing a special verse recitation and Pastor Ed....well, maybe I won't go there with this one.

But did you know that Pastor Ed was actually the original Sound/Tech guy for our church? He was the first to use Pagemaker and make the Sunday bulletins and he and Kelly bought the first PostScript printer for our church b/c they were only ones making money when we were first starting. They helped fund an audio translation system b/c we used to be a more bilingual speaking church. He was the one running the cables, electrical, etc... He's the original Tim Fitz!

Just wanted to give a shout out to Pastor Ed! I think that's why he's always supporting all of our tech/sound endeavors. He's always for us!

ProPresenter Dual Head

So....we're always trying to be efficient where we can. While browsing the ProPresenter site I found out that we could take advantage of our Matrox Dual-Head adaptor and have one laptop output 2 different images with ProPresenter. What does that mean? It means that one person can control the main slides that everyone sees (words with nice background graphics) and then output a different slide just for our singers. It's hard for the singers to see the words if there is a lot of graphics - esp since our screen is so far away from the singers.

We did have to pay for an extra module in ProPresenter but the huge benefit is that we need one less person for ProPresenter then.

Kudos to Emily and Jackson for working on this and getting this done!

RISE-ing to the Occasion

Sometimes we face circumstances in our lives that are beyond our control and sometimes you feel like you're in way over your head. Even though preparing for the RISE event was something that I was familiar with having done NSWN setups and Pauley Ballroom setups. But something about this night just felt so different. I just never felt confident. I mean it was the same thing we had done before. But I just felt so unprepared and in the end I think we were. But I'm thankful for the people around me who really stepped it up as we faced some adverse situations. They really ROSE to the occasion. I'll try to tell a few stories below.

Most of the problems were actually triggered by a single event that couldn't have been foreseen really but ended up impacting almost every part of the tech setup. Tim was working on a busted light and as soon as he opened up the can, the DMX line short-circuited and sent an electrical charge back up to the main distro that seemed to jump over to all the other circuits. For some reason, this mainly affected all of our video transmission from our Kramer PT110s. The electrical spike went from the transmitters and fried the receivers, which didn't have any fuse unfortunately. So in that one spike, we lost three of our video receivers - Kramer PT120s. One for the wide screen and the 2 side screens. Man, that was painful. We dropped one receiver that we were going to use for Sean McDowell and replaced his with a regular RGB cable. How did we find those??? We gave that receiver to the wide screen projector. Then we proceeded to scramble for more RGB as we had to abandon the Kramers. We daisy chained the side screen projectors with RGB cables that we found more of!

Also Rich was having a heck of a time trying to line up the 2 projectors to make the wide screen. 2 Panasonic PDT5600s. At 5:40pm he looked discouraged and ready to give up. I pressed him onward and played Eye of the Tiger by Survivor to cheer him on. Here he is below trying to adjust the projectors.

Richard from lighting was distracted and asked us to shut it off so he could program the lights. He was in a time crunch too. He thought we were starting at 6:30! haha.

Our main ProPresenter laptop also went on the fritz and starting crashing and unable to start it up properly. Once we got it booted it started to be flaky. Now it's a highly questionable laptop. I tested it for the Sunday Service the next day and the headphone jack was not working.

Jackson swapped out the laptop with Mike's.

But b/c we swapped this laptop out and Mike's didn't have a Final Cut HD codec we couldn't play the video Conrad had made of the mentors. While Mike scrambled to get the codec I took out my laptop and loaded the video so we could play off of that.

Once we got all the projectors live we could see that the chroma key was working excellent. However the slides from Sean McDowell's laptop was super grainy and blurry b/c it was taking so many hops. So we ended up using 3 different scalers to make it all clean...whew. Part of it was b/c we had this center projector that wasn't a wide b/c it would handle just 1024x768 res images (like Sean's slides). The only draw back is that these other scalers didn't have a preview. Only the Corio has a preview.

But we were concerned the whole night b/c all the gear was starting to feel really hot. Then we heard that the video team was getting shocked touching their gear so we thought there was a short circuit somewhere for sure. This was an adventure and a half.

There were more issues like how we would record all the video footage and make sure the audio/video were in sync. For you super techies, we were running BNC across all of our cameras into the switcher and ran 2 XLRs from the sound board to the video switcher but it only takes in RCAs. So we had to use feed the sound board audio into a mixer to give an RCA out to go into the switcher. Next time - get a compressor b/c it overloaded the audio a couple of times.

What an adventure. It was a great learning experience. It was Esther's last hurrah with us and a transitional moment for Evelyn who will be taking her spot. I hope we all learned from this and can use this in our future endeavors.

We pulled out all the stops and everyone gave 110%. We had some serious Times of Crisis. Thanks to all who threw their lot in with us!

RISE Setup Details

As soon as we got to Pauley we had to make some game time decisions. The layout of the room was different and so we had to adjust somewhat. We knew we were going to go with a 90degree layout change from NSWN. But we lacked the space in the back we wanted for games. We ended up moving our sound and video to the very back of the room. It seemed like the best place to be and most out of the way. Only issue was we didn't know if we had enough ethernet for some of our video streams to the projectors.

Next, the stage layout had to be adjusted. This was minor but still delayed us a bit and took some more work.

We decided to leave a lot of space in the front of the stage b/c we wanted to have the mentors and the students in the middle jumping up and down!

One advantage we had over NSWN was we actually had more man power. I guesstimated that we had over 100 ppl helping with setup. That's just an awesome number to think about. We had 100 ppl helping unload stage pieces, truss, lights, sound gear, cables, road cases, etc...

Pretty much we were doing NSWN setup so I think most of us knew what was going on. We decided to make the side screens 3' off of the main stage so they would close and almost tight and then it would seem like the stage and screens were like a wall.

We used the FBTs as fill-ins on the stage for people in the front instead of on the sides as we traditionally do. This was only for the praise time.

We had to do a lot of eq and volume adjustments for the actors. They did a great job but we had to really push them up and down with the faders chasing them.

I have another post with troubleshooting. Check out my iphone recording of the Intro...crazy!

Interhigh - RISE

This past week our tech team has been preparing for Interhigh's RISE event. It's a special kick-off event for Gracepoint's regional youth ministry - Interhigh. We're going all out again for this event just like we did for NSWN. But we're doing things a little different this time.

1. We're rotating our stage and setup 90 degrees - thus we're going for a tighter look.

2. We're going to use word overlaying live video. We're going to do IMAG for the praise and overlay the song's words on top. We'll have a camera upfront near the stage with a wide angle doing the "jam cam".

Our video switcher has some pretty cool functionality. We'll be using 3 inputs for our Canon HD Cameras, and Sony PD-150 and another s-video input with the song's words coming from ProPresenter. Using a chroma key function we'll be able to merge the s-video signal (words) over the live feed of the singers/instrumentalists. Nice! It's a big change for us and a first. I'm looking forward to this monstrously cool effect. With the lights, haze (we got 2 more haze machines) I can't wait! It's no U2 concert but hey, I'm still digging it.

SWS Mixing Feedback

The all important part of learning is receiving feedback. So i'm going to open up this page to everyone. Please let us know what you thought of today's mix. Please give pertinent information such as your seating location (Center Section, 5th row back, 10th seat over) or as close as possible and if you were in the main auditorium or overflow and anything else that might be helpful. We welcome your constructive and informative feedback. Thanks!

Our gear - microphones

A new series of posts that I wanted to start on is the kind of gear that we use. People often ask what kind of gear we use for our various applications. Over the year we tried many different models of equipment and gear. Of course, we're still a small church and our installs and mobile locations vary in size and form.

Now, just to start this post, I wanted to talk about the variety of microphones we use for our speakers.

WIRED - we have about 2 handheld models we use: both from Shure - SM58 and SM58Beta. These are basically the industry standard of microphones. I've seen these used everywhere. The standard SM58 tends to have a stronger bass response than I like for most voices but the Beta is quite a bit more expensive.

WIRELESS - we use a variety here of different mic heads.

* Countryman E6 and E6i and B6 - the E series is the one that wraps around your ear and the B series is a lapel mic.

* DPA 4065 - this is a wireless head that wraps around both ears. We've become most fond of this mic head b/c of the response and the ease of placement of the mic head.

Koinonia Welcome Night

Last week we changed venues a little bit. For the Koinonia Welcome Night we did a much less intense setup compared to our NSWN. Our campus Bible studies have much less gear due to more constraints - setup time, man power, other overhead...

But we did still have our switcher/scaler. Very nice.

So we go leaner - smaller mixer, no eqs, compressors, no subwoofer, drum pad instead of real drums, fewer singers, only one electric and one acoustic....just to name a few.

The setup is much simpler than our normal setup. The one challenge that we have this time around is the stage. Classrooms don't make the best venues for a band and a skit but we gotta make do with what we've got.

We decided to put the 4x4x2 Joyland stage pieces behind the lab bench at VLSB b/c it seemed to look better - to have the skit farther back and closer to the wall. We put 6 pieces together to make the stage that we wanted. We placed the band on the floor and had about a 2x2 space for Pastor Ed to speak from. It worked out for him since we had the lab bench to his right so he could use it for his tablet and drawings.

Documenting NSWN

So here's the part of NSWN that is probably everyone's least favorite but also probably the most important - Documentation. Well, I know it's important for next year, so I'm using this post as an addl historical archive.

SWS - Behind the Scenes for ProPresenter

Here's a look at some Behind-the-scenes footage of our latest service at Pauley. We're a very, very flexible church so we make changes to best inform the congregation and to tweak our services to make them the best they can be. Sometimes that means making some last minute changes. Of course, we're usually totally on-time, planned, all together, 100% cool and under control - hahaha.

Pro Video Presenter - was awesome!

Remember how we played all those videos at NSWN and SWS at Pauley - on the center screen and side screens. Well, there was a little piece of cool software behind it all.

Thanks to Brad and the others at Renewed Vision for their help in getting us a trial license to test out their application in a real production setting. I have to say that everything worked out very, very nicely. We had a few snags but we worked through them. Our biggest complication was using PVP with ProP.

Here's how we did our setup:

* Although this was against best practices we did use the primary machine and the slave over a private wifi network.

* The primary was a MBP outputting to two projectors via a dual head matrox external video device powered by USB. This gave us a resolution of 2048x768.

* The slave machine was a MBP outputting to 2 side projectors via a kramer pict tools 1 --> 4 duper. Basically the same image to both projectors.

* Imbetween we used a Kramer scaler vp710 and Corio scaler to manage the middle projector and side projectors.

* I can give more details if you'd like. Some of it is documented on the previous posts.

A VERY NICE about the PVP software is that it'll playback the video in the resolution that the machine it's on is playing. So the primary could output to 2048x768 and the sides could do 1024x768. We didn't even take advantage of the tiling...partially b/c of license constraints.

We're in the process of evaluating the software and will determine shortly how we can integrate this into our present environment at Willard Auditorium.

Imagine If...

We could have service at Pauley every Sunday. Wow, to think that we could have a facility so close to campus would be so nice for everyone. We'd have to do 2 services and the setup would be a little lighter than the NSWN setup. I think setup would be a solid 2 hours but I'm sure we could streamline some of this. The only thing i would see as a problem is the stage pieces...maybe we could leave some at Pauley. But I'm getting ahead of myself here.

Imagine just having this every week!

OK. I'm dreaming. But I can dream right? being so close would be so nice. Anyway, just dreaming out loud.

NSWN 1 and 2 are over!

It's hard to believe but we're done with both welcome nights! I just want to thank everyone for all their hard work. Everything went so smoothly. I think our hard work and advanced prep was crucial and really effective in preparing for the two nights. Great job everyone!

I wanted to document our timeline of events on Wed.

12:45pm - arrive at Pauley Ballroom Garage. Sound trailer, Overflow trailer, and Davis Trailer. The stage pieces were in another trailer and unloaded on Bancroft.

1pm-1:30pm - unloaded all the equipment by 1:30pm

1:30-2:45 - built the stage, instruments on stage, attached sound pieces to the truss. put up the side screens.

2:45 -4pm - put up the large 30ft screen, most of the lights were attached and ready.

4pm-4:45pm - began run through for skit

4:45-5:30pm - began run through for praise.

5:40-6:30 - full run-through

7pm - nswn starts!

NSWN 1 is OVER! NSWN 2 is TONIGHT

So NSWN 1 is over. I can't believe it. Praise the Lord! It was an awesome night. My rough estimate put our total at over 900 people at one point. We had to shuffle our upperclassmen and even sophs out to make room for the newcomers. That's simply amazing. And all the technical aspects were just right on. I counted only like 5 or so errors. That's like nothing. It was so smooth. I'm speechless really. Here are some pics Evelyn and I took during the setup and a few during the performance. Gracepoint Berkeley will have some more up later...

Oh and for our first time using PVP. There were some bugs and kinks to work out but props to Jackson, Irene and MK for making it happen. Let me tell you there are few pressure situations like that one. AND this was Allen's first time on the board mixing for the skit. Great job all!

NSWN - WEDNESDAY

Setup for our NSWN begins at 1pm today at Pauley Ballroom on the UC Berkeley Campus. I'm excited and a little nervous. Although this is just a single event, it's a huge opportunity for us to really welcome new students and connect with them and help them connect to the gospel. This is always the most important aspect of all of our technical endeavors. From the sound to the stage, to the lights, it's all about creating a safe, warm and inviting environment to share the gospel. And doing this well and creatively is what really excites me about all the work we do. Every we're faced with a challenge to do our best AND to have greater heart and care as we do it.

In this week's devotion text Jesus talks about how we ought not to take the seats of honor when invited to a banquet/dinner. But we should take the humble seats. As I thought about this passage and some of the reflection questions that followed I had a sudden thought...Why am I even invited to the banquet at all? I don't deserve to even be a part of it. And that's how I feel and think about my life with God and even to be part of something like NSWN. No matter what part of the church I serve in, it's ALWAYS a privilege. So as I approach the work, stress and battles I face today during setup and all the possible problems we encounter, I'm asking God for constant perspective and gratitude.

See y'all tonight!

What's New at NSWN?

So, what's NEW this year at NSWN? Well, actually, not that much. We're doing a setup pretty similar to last year and in fact we've simplified some parts of it. We actually have fewer lights... But one addition we're adding is Pro Video Presenter. This is a big time software tool from Renewed Vision. I mean the big guys use this tool. Too bad we're not a big guy =(. We were able to rent one for a week to demo and see how it can work with our current setup. It's a great tool. How are we using it?

Well, if you've looked at our setup diagrams, which I'm sure everyone has thoroughly studied =), then you'll notice that we have 3 screens. The side screens are hooked up to one laptop and the double-wide center screen is hooked up to a different laptop. We want to play our new and exciting video on all 3 screens. But we ran into a few problems:

1. Center and Sides are at different resolutions - 2048x768 and 1024x768.

2. We're using HD resolution this year - 720 which is 1280x720. So the video natively will be a bit smaller to squeeze into the 1024x768 and won't use up the entire 2048x768.

3. Center and Sides have different inputs. How do you sync them?

We could play the video on the center only but we want everyone to see it well. We could play it on all 3 with smaller projector resolutions (1024x768) but that would be too small. Or we could play it on the center screen with the wide resolution and the side screens. But the different resolutions is what makes this so hard. So let's play them separately on each laptop. But how? And this is where Pro Presenter Video comes in. Using a special network protocol (yes over wifi), the software can sync itself across both laptops! It's amazing.

I'm sure I've confused some of you. Just come tonight and see it happen!

First SWS of Fall 2009 - Back at Pauley!

On Sunday, we went back to one of our favorite venues on the Berkeley campus. Few rooms can hold as many people and have such a large and great feel. We're lucky to have a room like this. We can bring in all of our gear and do the setup of our choice. It's a grand open space for us to work in and I love it. We did a similar setup as last year and our Saturday workday helped us prepare really well for the setup. Here are some pics of our setup - from the garage to the service.

NSWN Behind the Scenes - NL workday

We spent this past Saturday - from 1pm to almost 10pm setting up our potential design for the NSWN this coming Wednesday - in 2 days! We also got to setup for our SWS service at Pauley. For our first week back in a full scale Sunday Service I thought everything went pretty smoothly. I can only acknowledge the help of so many people who came out this past weekend to make it all happen. Thanks to everyone!

I'll try to describe what we did in a nutshell...We cleared some space in the NL MPR. We brought out all of our stage pieces - rentals and from Willard. Rental pieces are 4x8ft. Willard pieces are 4x4 Black pieces and 4x4 Joyland stage pieces and 3x8 wooden brown pieces. We setup the truss pieces - 10 x 3 for the main truss on the super towers. Then 4 x 10ft pieces on 4 large pass stands to be the posts for our 10ft screens and to hold some of our moving lights. The truss on the towers will support 3 projectors (2 at 5000 lumens, 1 at 3500) and 2 Ev non-powered speakers, and an array of Par 64s. We're doing things a little differently this year.

NSWN Behind the Scenes

Here are some pics of the layout of what we're doing at Pauley. It's my chicken-scratch handwriting but you'll get the idea. I'll try to post a better computerized diagram at some point.

Basic Speaker/Audio Layout

Basic Vocal/Instrument/Channel Assignment

Projector/Scaler/Screen Layout

Trailer List

Overall Layout

There's a lot more to each of these drawings and just tried to dump them out on some paper the other night. I'm starting with these to instruct/inform others.

Saturday is a major workday for us 1-6pm to do a test of all of our gear. Since all of our gear has been in trailers all summer we're just making sure everything still works as we expect. We'll also be testing out the new video on a wide screen. At one point we thought about making it a 3 screen projection system but we don't have a wide enough screen =(.

More pics to come soon.

The Fall - NSWN

The summer has been real quiet for our Sound Team and our SSL Team. We haven't had to setup for Sundays for months now b/c we've been in home worship. But we're back and in full force. We have our first corporate Sunday Service at Pauley Ballroom on the Berkeley campus this Sunday. Then we have two nights at Pauley for NSWN - same event both nights. And then we have another Sunday worship service at Pauley the following Sunday. And then we're back at Willard. Whew....We got a lot going on in the next few weeks. So I want to document everything we're doing so check back here often.

Here's a slideshow of some of the pics from last year's setup first SWS setup. NSWN changed a bit after that. but you'll get the general idea here.

I wanted to show people what goes on behind the scenes of some of the planning. I have been too busy to take pics of all the things I want to but maybe this Sat - our tech run through - we'll have some time. All the stage, lighting, sound and video stuff is really coming together. You'll see that in some of the posts after today.

Josh Wilson Music Video

This is one of my favorite artists. He's sort of a one-man band. I love how he uses a lot of effects and loops his own music. Kind of a cool rendition of Amazing Grace.

Audacity releases 1.3.8 for Mac

Audacity just released 1.3.8 for Mac recently.  It's still a beta version but so is most software nowadays.  Seems like they've added a bit of new tweaks and changes that are quite nice.  Here are a few i've listed that i like:

Effects:

• Faster Equalization and Noise Removal; improved Truncate Silence and Click Track
• Faster waveform drawing and better response in multi-track projects

Interface:

• Draft Manual/Quick Help included in Windows and Mac installers
• New "Mixer Board" view with per-track VU meters
• Mute, solo, gain, pan and track height saved in projects
• More compact Preferences window with easier-to-use Keyboard tab and new toolbars shortcuts
• New Screenshot Tools and improved screen reader support
• Upon export, addl ID3 tags revealed and editable

But you get it download it and try editing some files.  We'll also post a tutorial to get ardour working on your machine at some point as well. 

Skype vs. Oovoo

I've decided to look into Oovoo to see if this product would be better for us to use over Skype for our video conferencing needs.  I'll list out some of my initial thoughts, which assumes you're already familiar with Skype.  Our main issue with skype that i want to resolve is the problem that Skype doesn't import the video AND audio; it only does the video.  So we get some syncing problems when using a dv camera. 

Oovoo Video

Pros: 

* 2-way, 3-way, x-way conference calls

* 2-way video sessions are free

* 3 different levels of quality - low, standard, hi

* 3 levels of quality directly correlate to bandwidth and cpu usage. 

* more manual adjustments for audio than skype.

Cons: 

* UI is awful.  a millions widgets and buttons without a clear flow or purpose

* Cpu utilization overall is high b/c it's written in java

* crashed on me several times (mac install)

* 3-way and up concalls require a paid memberships - starting at $7.95

-->  I'm still waiting on the main point of making sure the audio comes with the video in the dv stream.  I'll update y'all later on this one. 

Who is Taking MYT Audio?

Hi,

if you are going to or were or still are taking MYT Audio let us know what you would like to learn more about.  What did we cover that was too fast or you'd like some more info on.  What are you curious about?  Comment and let us know.  I'm trying to get this blog going again =-). 

What is Feedback?

Well, we sure heard some of it last Friday at the Ei8ht Hour Shift Concert at First Pres.  The concert was great except for the feedback.  and trust me, i was dying. 

So what is it?  basically a sound loop that keeps increasing in volume until you get that ear piercing sound.  that's the common understanding of it.  How does it happen?  Well usually it's from an input, like a microphone that is too close to something like a speaker.  The speaker, you see, is outputing or sending out the voice or audio input from the mic and b/c the mic is close, the sound from the speaker is going right back into the mic, which is coming out of the speaker and into the mic and then you have a natural disaster like feedback.  and let me tell you it can be a disaster.  i was really pushing the limits this past weekend at the sound at 1st pres.  

this is why i love our in-ear system by Aviom.  oh well, won't be touching those until the fall!  but i can't wait. 

Using Skype with DV cameras for JCC and GLIVE

Many of us know Skype as the software product that allows us to do a phone conversation or a chat (video or audio) session with our friends and in particular with friends abroad - all via the internet. When my friend George was overseas we used Skype for a video conference with him and some of our friends. 

Most recently, we've taken Skype to a new level - when we broadcasted JCC and then GLIVE. We've even "skyped" people for meetings and such as well.  So let me explain some basics here.  This is delving a little into the video world but you need to understand both to see how this works. 

Here's the flow:

Mixer Board (xlr) --> DV Video Camera (dv) --> Video Switcher (dv) --> dv repeater (dv into computer and dv deck*) --> Computer with Skype (audio input from Dv Deck) --> Recipient Computer with Skype

Flow for this setup is relatively simple.  But this is a much larger setup. We use the video switcher b/c we have multiple cameras and inputs coming into the switcher.  Usually we have 3 cameras and an S-Video (pro-presenter/slides).

For a single camera setup, it's similar:

Mixer Board (xlr) --> DV Video Camera (dv) --> dv repeater (dv into computer and DV deck*) --> Computer with Skype (audio input from Dv Deck) --> Recipient Computer with Skype

* the reason that we need the dv repeater and the deck is b/c Skype cannot handle the video and audio stream in the dv input.  i don't know why but it will not accept the audio input, so we need to grab the audio from another dv device, hence the repeater. I'm sure i've confused a few of you by this point.  that's b/c it is confusing.  hopefully skype will resolve this issue and then we could just plug the dv camera right into the laptop and we'll be good. 

So this is a rough presentation.  If you have more questions i can try to fill in the gaps. 

Want to learn to mix better?

This is something i know that many do want to do better. but it's hard to get as much practice time as we would like b/c we need the live band and such. So i thought we could try some training sessions of mixing via some old praise sets that we recorded onto 24 tracks. using some software you would be able to eq, add effect, solo, and mix a set. at first this would be through software.

if we get enough interest, we can setup our large mixer at NL and in a room somewhere and try to recreate a studio effect and use our firepods to play back the recordings and you can try a "live" mix.

so what i need to know from you guys is:
1. do you own a mac? what kind?
2. can you spend about a 1.5 hour session with me to install the software and learn to use it?
3. you will need at least 20 GB of free space or an external drive
Please comment.

couple caveats: this is not the same as live mixing. in fact, it's really different. but you can at least begin to learn some of the mechanics - soloing, eq'ing, mixing, listening for instruments, etc... this is reallly post-production but you can at least begin to learn some more...

Zellerbach Acoustics

While waiting for Sang's graduation to finish, I decided to check out the room's sound setup/acoustics. This is always a good practice when you enter a room like a theater or auditorium, etc... What observations can you make about Zellerbach from these pics?

General Power Understanding

ok, this is going to be a very rudimentary lesson on power.  but just want to help you understand and be aware of how much power you're drawing and using in a given situation. 

watt - describes how fast a circuit uses electricity

volt - basic unit of electrical pressure or EMF

amperes - basic unit of electrical current - flow of electrons

* courtesy of this dictionary

Standard US voltage is ~110.  

Most devices are measured in watts. 

Most outlets/circuits are measured in amperes or amps.  

Here's the formula --> amp = watt/volt

e.g. You have a 1000watt projector plugged into a US outlet that is measured to be 110v. You know the circuit you're plugged into is only 15A.  Will you be OK? 

1000watts/110v = 9.1A 

Yes, you will be ok.  but you could not plug two of these projectors into the same circuit or else you blow the fuse. 

Most wall circuits are 15-20A depending on when they were installed b/c older electrical work often only had 15A circuits/wiring installed. 

ok, but the big question is what does draw a lot of power?  here's a short list:

* projectors and lights (look at the bulb wattage)

* amplifiers - esp for the subwoofers.  at normal usage the actual power draw will be low but if you get a real thumping song then the amp is going to push more sound to the sub, which will require more power and the wattage/amperage will increase. 

* b/c these are in our environment - rice cookers or water boilers - basically anything that heats up something. 

* microwave, hot pans, etc...

* vacuum cleaners

***last note: something that may affect your power in international settings, is what Hz the current is alternating at 50/60.  in the US it's 60Hz.  Europe and Asia is 50Hz.  If you do not verify your equipment is running at the correct voltage or frequency, you could severely damage your equipment.  Yes, the equipment would run but it could also be burning out the wires internally.  ouch!  

Recording/Resampling audio

Just so we're all on the same page about what we use for recording and how we do recording...one caveat is that this is Mac-centric b/c most of us use macs.  

1. Recording Software - Audio Recorder (make sure you install lame mp3 library)

2. Resampling Software - iTunes LAME

3. Editing Software Free - Audacity for mp3

4. Multi-track recording and editing Free Ardour / Jack for Firepods

5. Multi-track recording and editing Paid - ProTools 

I mentioned this in a comment but I'll say it formally here as well...

"..we use a program called iTunes-LAME at the recommendation of Mosaic b/c of podcasting purposes. we use the following setting: -v -V 6 -m m -h --resample 44.1. their technicians recommended this setting for podcasting b/c it makes the playback better. the file ends up being about 1/2 the original size.""

Compressor Settings

Let's try out these settings that are suggested from Rane. I think Esther is at the board this Sunday.  let us know how it goes.  you're going to need to spend some time on going through each of the compressor settings during run through. 

Comment afterward to let us know how it went.  Maybe Dennis can try this up at Davis as well and let us know how it goes. 

What would you like to know?

if you're taking MYT, what's something you would really like to know/learn about sound? leave it in the comments. 

even if you're not taking myt, what would you like to learn about sound/pro audio? or our own sound/band setup? what would you like to see different?  

i'm just looking for specific feedback for myt, learning and also general feedback. 

GLIVE tech - part1

i wanted to do a background post on what we did for GLIVE.  it's both for archival and anecdotal reasons.  this'll be a several part series.  i'm going to start with some bkgd pics.  we had a work day 2 weeks prior to the actual performance.  we got volunteers from the junior brothers and some ssl lighting folks and we started by setting up the stage, then  SSL was working on lights and we were busy getting all our wireless units in order (16 units - some borrowed from waypoint). 

the crucial addition we had this year was a 2nd lift to help speed up the work with all the lights.  we actually rented fewer lights than the previous GLIVE.  in case you'd like to see, i'll link some of the pics of the performance.

Sound System at Willow Creek

Here's an article of what Willow uses for their sound system.

i remember talking to Chris Gille and his wife when they were discussing the plans for what kind of sound system they were going to implement in their new auditorium. Meyer uses some cool embedded technologies to capture the best sound no matter where you are in the auditorium. Their array speaker system has a controller that "speaks" to hundreds of nodes that are placed all around the auditorium during the install to ensure that the sound travels uniformly and at the best fidelity.

Willow also was using some pretty cool subharmonic subwoofers from Bag End.
