I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want 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 it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers

Best way to hook up Bose 901 series VI to a Harman Kardon HK3490


According to the HK site, "Stereo pre-amp outputs let you connect the receiver to an external power amplifier." So it's easy. Connect the Bose equalizer in the pre-out / amp in loop.

Recently I bought a Harman Kardon HK 3770 Stereo receiver. My question is " can I use a Bose 901 Series VI speaker with this receiver?, since I plan to buy a 901 S VI speaker.. The receiver has no tape...


From the description of the Harmon Kardon, it sounds like you should be able to use the speakers, but you will not be able to use the active equalizer. The equalizer is designed to be cabled into the tape monitoring loop and allows you to listen to the equalized signal coming back into the receiver. Attach the +/- speaker wires to the right and left channel speaker connectors on your receiver.

How do I connect my bose equalizer to my pioneer amplifier


The manual is at Bose.com.

In any question regarding connections the exact models of all parts in the scenario should be defined.

"Pioneer amplifier" is not unique nor revealing. Integrated amplifer? Power amp? Tape Loops available? Pre-Outs? What's involved as a preamp?

The key thing to know is that any amplifier channels driving 901's must not drive other speakers as the Active EQ severely modifies the Line Level source input. If the EQ (or any sound processor) is used in a Tape Loop on a modern multichannel digital-audio-capable AVR, ONLY 2-channel analog sources will function when the Tape Loop is engaged; and all downstream speakers will be affected by the processing. That's par for the AVR course.

Bose 901 use in multichannel applications (which I have) will require access to Pre-Amp outputs for the chosen channels (likely the Front) and you will need to get a separate amp for the 901's, placing the EQ in series with the chosen amplifier. I currently drive mine with a Carver MT-200T.

AVR 1600 receiver won't connect to bose series III EQ


You mean BOSE 901 Series III Active Equalizer; and HARMAN KARDON AVR1600 right?

Sure it will. It goes in a Tape Loop such as Tape Out/In or Video 1 Out/In. But it won't work for anything except analog stereo sound sources as all digital audio is not available to the RECORD OUT jacks when the Tape or Video 1 is activated. AND 901 Active EQ is intended solely for 901's, not any other speaker system

The HK has no Line Level volume-controlled Pre-Outs so you're out of luck if you want the 901's to take part in a multichannel setup, which would require a separate power amp to drive them anyway.

How do you hook up the Bose 901 series VI to a Harman Kardon AVR 510 receiver?


Search Fixya for the dozens of times I have answered this type of question. The central theme is you will need a separate power amp for the 901's and use of the Pre-Outs.

Hi There, I have a Marantz SR7005 Receiver and Bose 901 Series VI speakers with the Bose equalizer. I'm struggling to figure out the best way to connect the Bose equalizer/speakers to the SR7005. ...


It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

I have harman kardon AVR 230 7.1, Can it run my new Bose 901 VI speakers, how i will connect the Bose EQ ( 901 VI EQ) to this AVR?


I have a setup similar to what I think you're trying to do and it works great!


You're in luck because you have a full complement of pre-outs. You'll need a separate amp for the 901's.


First some background.


The use of 901's Active EQ (or any external proxcessor) in any digital AV receiver setup for anything EXCEPT STEREO listening through the 901's alone requires you to have a separate amplifier for them and to avoid having to use a Tape Monitor which could introduce proprietary and potentially damaging Active Equalization back into anything in the AV Receiver with its conventional speakers.


In an AVR, if you activate any Tape Monitor circuit at all, you will kill any digital sources. That is a function of AV receivers in general, nothing to do with 901's. Your Pre-Outs get us around that possibility and limitation but it also means you need a moderately powerful amp for your 901's. I use a Carver MT-200.



Run it with the Active EQ between the receiver Front L and R Pre-Outputs ** and the 901's amp channels.


** Front Pre Out (or one of your analog Tape Outs) >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.


The AV Receiver can still drive the Center, Surrounds and the Sub(s) as it is designed. This is how mine is wired.


Then set the new amp's volume control (if it has one, mine doesn't) to something HIGH and leave it alone. Run through your speaker setup routines on the AVR. After levels and distances are set the AVR will be the boss of the 901's. With 901's don't even need subwoofers but they don't hurt. If you do have subs I recommend sharing the LFE with the 901's.


I've done this in my own setup once. Turn the 901's around so the rear faces point into the listening area. Crank up a movie like Master and Commander and when the waves are crashing or cannon are firing you WILL FEEL A BREEZE from them. Now THAT is multi-media! I advise having the 901's share LFE with any subwoofers you might have.

`Which ampliphier is compatible for my Bose 901 series 6 with equilazer.


Ideally, an amplifier or receiver should have either a "Tape Monitor" selector switch and Tape Input & Tape Output jacks, OR have Preamp Output & Amp Input jacks to enable insertion of the Bose Active equalizer into the circuit before the amplifier stage. Power requirements - according to the 901 Series VI manual:

"Your 901 speakers are designed to work compatibly with receivers or amplifiers rated from
10 to 450 watts per channel."

Connect Bose 901 VI EQ to a Harmon Kardon AVR 247 Amp


Similar problem...I came up with a solution with help from Onyko. For my receiver, at least, the bottom line was that the output from the equalizer MUST go to 'Receiver, Tape In'! Since that is the ONLY input source from the equalizer, you must combine elsewhere. Part of my setup included the Radio Shack Audio/Video Selector box which costs $21.99...you might not need it, but in my case, I couldn't plug all components into the back of the receiver and have them go through the equalizer.

Since I have a satellite receiver, DVD player and TV, that I want to route through the equalizer, here is the way mine is set up and working:

Satellite receiver and DVD player out to Radio Shack audio/video selector

Audio/video selector out to VCR in.

VCR video directly to TV

VCR audio red/white (audio) out to equalizer

Equalizer out to Receiver Tape IN (Receiver Out not used)

Hope this (or a variation of it) helps.
