Temple De Hirsch Sinai Bellevue Sanctuary Sound System

Temple De Hirsch Sinai Bellevue Sanctuary Sound System
Rabbi Daniel A. Weiner liked the new system in the Seattle Chapel so much he wanted the same for the Bellevue Sanctuary. That building was built in 2001 so it had some acoustic treatment built into the design. Consequently we didn’t have to install any acoustic treatment to correct any issues.

The facility has a u shaped seating area with a balcony, which was a bit of a challenge as far as coverage. Because of the excellent coverage character of the Bose F1 Line Array system, it was a good fit here as well.

The Old System
The old system was fine for speaking, but not for a full worship team. As you can see in the pictures below, the system consisted of Renkus Heinz speakers mounted on the lighting truss. 3 speakers facing down to cover the u-shaped seating area. There is a sub-woofer installed in the wall to the left of the platform. The only problem there is the amp rack for the system is located approx. 100’ from the platform in another room. Consequently the sub woofer was basically non functional.

The New System
We left the old system intact and we are using it to augment the new system. We ran an output from the Soundcraft 32 Channel Stage Box to an input on the old system and patched it to a dedicated fader on the console.

Temple De Hirsch Sinai Seattle Chapel Sound System


Temple De Hirsch Sinai - Seattle Chapel

Jim Collier the Facility/Media Director expressed the concerns they have with the Chapel. Highly reverberant, noisy, just bad for music in general. We had to correct the acoustic problems with the new sound system install or the new system would just make the problem worse.

We installed 72 Primeacoustic Beveled Edge Panels (2 ft x 4 ft x 2 inches) into the room which corrected the acoustic problem.

Next, the new system, Bose just came out with their new portable line array system (Bose F1 system with subs). So after looking at the physics and the design of the Bose system we felt it would be a perfect fit.

We weren’t wrong the system has clarity and has plenty of power to handle anything they could throw at it. The bottom end is very tight and punchy.

We did an impulse response test on the room before and after the install. This gave us a Sound Signature of the room before and after.

Here is the result. We ran a male shout and a female shout through the signature files of both and this was the result.

The first is the male shout in the room before install followed by the after install, then the female shout with the same order. Read More...

Life Change Church Seattle - New System

Life Change Church Seattle


Associate Pastor Art Nelson would like the room to sound like a recording studio control room. His comment on the existing system: It has a mushy bottom end, with it sounding very different depending on where you sit in the seating area.

Project: Upgrade Sound, Video, Acoustic Treatment, and Lighting

Design Parameters:

  • Acoustics - room to have a sound signature similar to a recording studio control room. Adding bass traps, panels and diffusion. (see drawings below)
  • Sound - Total new system, converting to digital, centered around a Midas M-32 mixer with 48 channels to platform. Speaker choice is the ISP HDL 3112 3-way line array with the ISP XMAX 212 Sub Woofers (all active) XTA processing and installed in a LCR configuration.(see SketchUp drawing below)
  • Lighting - All new lights to be LED including house lighting. Some par fixtures and a lot of robotics.

Existing System:
  • Acoustics - None, no acoustic treatments of any kind in the existing room.
  • Sound - 2 x EAW Passive MK Series Club Speakers, Mackie SWA 1801 Active Sub Woofers, QSC amps (mains & monitors), Mackie SR 32-4 VLZ console, 4 stage pockets with 8 x XLR & 4 x 1/4” connectors.
  • Lighting - House light consist of residential hanging globe fixtures and track light for stage area.
  • Video - projection system on to a painted-on-wall screen in 4:3 format approx. 100” diagonal
  • Room size is 40’ x 40’, so this is a small room and their is a lot of energy put into the room from this system. The speakers are mounted in center cluster configuration, running mono. No processing of any kind, and amplifiers are located at the sound booth.

Home Recording Studio Drum Platform Design

Controlling drum leakage in your recording space, is probably the biggest problem in the home recording studio.
One way to solve the problem is to record the drums in the studio area while the rest of the band is recording in the control room. No more leakage but the scratch tracks are pretty much useless because of the leakage in the control room.
One problem solved and another problem is created. There has to be a better way.
If you isolate the drums properly, the leakage from the drums in the adjacent mics is not a problem. So what is the best way to isolate the drums?

The Solution: Build This

Church Sound

Church Systems



Most church buildings today are not designed for sound, so even the smallest church building needs a sound system. Therefore the sound system is the cornerstone of every local church.

Why do churches go through at least 2 sound systems before they get one that really works?

The reason is that the music stores don't usually have the churches best interest at heart. While they do have good equipment, they usually don't have the necessary skills to determine your needs?

Do you think of speech reproduction first? or Do you design for music reproduction? There is a difference and You can have both. Read More...

First Baptist Church in Tacoma -Sound Booth Complete

Well, here it is, the completed sound booth. We raised the floor one step ( 7” ) which gave better site lines and now all the personnel running the service can see the platform clearly. The sound from the main speakers has a clear path now.

Home Recording Studio Sound Proofing

This too could be yours a SSL 4048G
For years now I’ve been on the search for the most practical, beneficial sound proofing material for Home Recording Studio. I now feel it is possible to build a quality home recording studio inside a home or garage. With basic construction skills you too can build a professional level recording studio in your home. Here is a case study using Quiet Solutions product to pull it off.

First Baptist Church in Tacoma - Sound Booth Overhaul

The First Baptist Church in Tacoma gets a Sound/Video Booth overhaul. They have a very tight space and a lot of gear. We took their equipment list and put together a very efficient design. The install takes place from Jan 21 - 23. We are also raising the floor one step (7&rdquoWinking to get better visibility for the sound/video personnel.

Dimensional Drawing of the new sound/video booth

Phase One of the overhaul was to move the monitors amps down to the platform. We did that in Nov ’09. The amps for the mains are still in the booth (as you can see on the audio rack on the right side of the booth).

Phase Two - the design, construction, fabrication and install of new booth.

Once the install is done I will post an update.

First Baptist Church in Tacoma - System Rewire



sanctuary from balcony sound boothSoundcraft GB8-40 board in sound booth
Chris Pak from First Baptist church in Tacoma contacted me about their system a few weeks ago. They felt that the system was not operating properly and there were some wiring issues regarding hum in the system. I don’t know who designed the system but I did meet the installer. The amplifiers were placed in the sound booth under the mixer, feeding the monitors and the main speakers from the balcony. The system design consisted of a center cluster with additional speakers for side fills all located behind the suspended ceiling.
The cluster: 6 boxes of McCauley M120 speakers, and 2 subs cabinets (mounted one on each side of the array) not sure what the side fills are.
The processing for the system: DBX Driverack PA The driverack was set to a JBL 3 way speaker system with subs. (The McCauley system is a 2-way box)
The sound was very thin and I could tell that the mids where none existent.

We programed a custom setting in the driverack and the speakers came alive with all kinds of good sound.

How Important is it to Aim Speakers?

I just finished correcting a problem at the St Joseph’s Catholic Church in Issaquah. The problem was a very reverberant space with lots of echo. In the sanctuary there wasn’t a lot sound absorbing materials, tile floors, plaster walls in a basic rectangular shaped room. The 4 speakers providing sound to the 4 seating areas were located in the skylight structure. see pics Read More...

How to Build a Home Recording Studio Recording Studio

First off this picture is not a picture of a home recording studio. It however a good example of what to target towards.



I recently was a invited to see a ministry that is in the process of building a recording studio in Seattle. Not sure who did the design but they definitely need to go back to school and learn acoustics.
They are taking 2 rooms of an existing building, and converting then to a recording studio.
Problems:
First off the Location of the building is on a major artery to downtown Seattle. Trucks, rush hour traffic etc. Solution: Major money has to be spent to build in insolation from ambient and transferred sound (through the floor and walls)

2nd Design: They have designed a literal box within a box. While this helps with insolation it does not deal with the acoustics of the control room and the studio (parallel walls etc.) This situation produces Standing Waves. This will really cause a bad environment to mix in. Read More...

What is the best Projector for my Church?


Quantify whether you have the ability to do a rear projection system.

If you can do a rear projection system anything above 2000 lumens will work. Provided the space behind the projector is enclosed and ambient light can be controlled in that enclosure.

Ingredients to grow a church

1. The pastor better be a pastor, someone who loves people, a people person.
2. Grounded in the word
3. Have a great sound system

The last one may sound funny, but it is very, very true. If the congregation can't hear the word, or the vocal intelligibility is poor, the church will not grow. I have a good case in point. A baptist pastor called one day and asked if they could improve the vocal intelligibility of their system because the older members were having a hard time understanding the pastor's preaching.
