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...

Sound System Training Test


I’ve added a link to the online interactive version of the “Test” ( see link in sidebar) or you can take the Test right here right now. Here is the “Test”




The online version does not have any questions from page 3 of the downloadable PDF file but is quite entertaining. It will give you a grade when you are done.

download “Audio Console Test” here

This is the test I use in my training seminar. For church media worship ministry leaders this will help you find a competent sound system engineer.

The biggest shortfall in church audio engineers is their ability to create a mix. They pretty much have a grasp of the functions of a board but lack the mixing skills. This is why I created the test, to reveal what they know or don’t know.

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.

TV Show Audio for Video

We just finished doing a pilot (4 shows) for V-Boys Productions. The show is a talk show format similar to "The Vue" but with a Christian perspective. The Show is called "The Vanessa Waller Show". We provided the audio recording for the shoot. Here is a picture of the set.

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...

ISP in Idaho

We just finished doing an install of a pair of ISP HDM 115 speakers in the All Saints Presbyterian Church in Boise, Idaho. We had to create special brackets for the beams in the sanctuary. As you can see from the pictures, the beams have different angles from one side to the other. Here is a picture with the old speakers (Mackie SRM 450) and what it looks like now.

United Church Complete


Well here we are all finished with the install. We moved some of the equipment we replaced (with the new equipment) downstairs to a multifunction room. Put it all in a rack (see above pics) We also brought a feed down from the sanctuary so they could use this room as an overflow. Read More...

United Church ISP Install

Original Speaker LocationNew Speaker Location is forward from old speaker location
We just finished the install at the United Church in University Place, WA. We changed the location of the speakers along with new ISP Speakers. The front pews really don’t need re-enforcement because they are close enough to hear everything naturally. That allowed us to install 2 overhead choir mics for the choir. The comments from he congregation were “I could hear everything clearly for the first time in years” Read More...

Thoughts on the new McCauley M Series Line Array

I recently when to a church service where they had a new McCauley M Series system installed. The configuration consisted of 7 x M-90 modules, 1 x M-120, 2 x MS1 and 1 x AC355 per side. The sanctuary is a 80' x 80' x 26' (WxDxH) with a balcony.

The 2 MS1 cabinets where flown in a separate array next to the main array. I noticed some interesting things (no mids) with lots of sizzle in the high end. They had an acoustic guitar player as well as an electric guitar and you couldn't hear either one. The vocals where not very clear either. Because they did almost 90 degrees of vertical coverage they had some slap back and early reflections in the seating area. Read More...

Church Systems - should they be Mono or Stereo?

Churches have migrated from the bullhorn and soapbox to fairly large complex sound systems. Most church buildings today are not designed for sound, so even the smallest church building needs a good sound system. Why do churches go through at least 2 sound systems before they get one that really works? Read More...

Church Sound Systems - Update every 5 years?

It seems that every 5 years from an install I get a call with comments like "Our system just doesn't sound good anymore" or "We need a better system". If the system was great 5 years ago why the indifference to it now? The answer is that we quickly get used to the way it sounds. The best remedy to an ailing system is to have it tuned. Every sound system needs to be tuned at least twice a year. Read More...
