Question about Audio & Video Receivers
Need Faceplate for Akai 747 Dbx-Black
SOURCE: Help with Live Sound
I am available as a sound system designer. Your request is a bit simple. Given the complexity of the situation there are way too many factors involved to give a simple one or two paragraph solution. Installing a sound system involves several areas of expertise. 1. Acoustic analysis of the venue. 2. Analysis of the electrical system. 3. Budget! 4. Procurement. 5. Rigging 6. Operation and maintenance protocols. Fixya is an advise site for do it yourself solutions. If you want advise. My advise is to find a consultant, pay them to give you a sound system design, buy the equipment new or second hand. Hire a competent sound engineer, carpenter, rigger, licensed electrician who can build and install your PA in your venue. Best of Luck!

SOURCE: Bose 901 Active EQ Loop
There's good news and bad news. The bad news is that a multichannel receiver with Bose 901's will only sound right in STEREO on stereo analog material. For one thing, the other speakers around the room are not designed to recieve its Active Equalization and for another, if you engage your Tape Monitor you will not be able to play digital sources. Tape Monitor is for analog stereo material only and on my receiver it disables any digital inputs.
The good news. I have a setup similar to what I think you're trying to do and it works great!
A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers. You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W).
Run the dbx and BSR in tandem with each through the tape monitor loop on the receiver but be advised you can only use them on analog source stero material. However, you can still employ the various DSP options to spread the sound around the room.
At my PC workstation across the room I have a stack of analog processors and sources including dbx 3bx-ds, dbx 120x-ds, BSR Spatial Enhancer, BBE 462 Sonic Maximizer, SS-525x EQ, Carver C-9, dbx-224x, JVC cassette deck, Dual 1249 Turntable running through a Garrard MRM-101 Preamp, Pioneer PDR-509 CD Recorder and the Media Center PC stereo analog channels all running through a dbx 400x Program Route Selector (a godsend) which is attached to my ONE TAPE MONITOR on my Pioneer VSX-36TX Receiver. Of course, I have some of my analog processors running in tandem, too, since the 224x only has three processor and three tape loops.
For listening/recording anything 2-channel analog I engage the stack through the Tape Monitor. For everything else I turn the Tape Monitor off. The nice thing about the stack being separate is that I can doodle with recording and use headphones while the TV/DVD/Blu-Ray do something else.

Here's some schematics I found on the net:
Not sure if they will help, but they might give you a clue.
Couldn't find anything else- you might try to contact the manufacturer on their web support site.

Of course it will work, as any processor would, but this type of encode/decode noise reduction is really for media that have inherent noise to begin with, like analog tape. Digital recording on media with reasonable dynamic range capabilities would not benefit from it.
If you DID ENcode your recordings with something like dbx noise reduction you would have to DEcode it for proper playback, so you would be dependent on its availability for playback.

Be advised that the engagement of any device in a Tape Monitor loop on a late-model Audio/Video Receiver will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.
The connections themselves are fairly simple but it pays to understand what happens in the loop.
In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).
Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.
The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.
EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Monitor as the first analog step in the process and defeats any pure digital sources.
In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? The rest would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor is activated. I don't totally agree with the engineers but that
