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.

SOURCE: developed a hum/extraneous noise problem.

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.

SOURCE: Will the tascam dx-4d

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.

Hello: I just purchased a DBX 128 and have no idea how to connect it up. I would like to listen to my records as well as tape using the expansion mode. However, it seems like it only hooks up to my tape...


Part 1

Let's establish a couple of things first.

1) You already have the turntable part working.
2) Your receiver has a defeatable Tape Loop.

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

Will the tascam dx-4d dbx work with regular mixer? Or do you have to have a reel to reel for this to work?

I am needing 4x slider pots for a dbx 213 graphic equaliser, can you get them?


The only places these things are usually available are in certain electronic stores in some parts of the world.
Although, if you have the website of the company that produces your device, you can purchase it from there online using a credit card. You can check under their accessories section for this product and if they have it, you can purchase it and have it shipped to you.
On the other hand, you can buy it from a third-party website like ebay.com and have it mailed to you.
Hope this solution was helpful?

I recently aquired a carver c9 sonic hologram generator without a manual..... from what I have read it can be hooked up between amp and pre amp but there are other ways? advantages?


A tape loop connection would allow you to bypass it completely, otherwise not much difference.

Attach it in any tape loop as you would any other processor or tape deck. Or get a dbx 400 Program Route Selector that supports 3 tape decks and 3 processor loops and allows selection and utilization of any or all before or after the tapes, while using only one tape loop on the receiver or preamp.

I have a C-9, a 400 and some other audio toys to justify having the 400.

The C-9 is interesting.
