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.

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.

I have a Harmon Kardon AVR 247 and I want to connect with Bose 901 VI equalizer. No other speakers are connected, just the 901's. Where do I connect the wires from the equalizer to the AVR 247...


I have this exact setup. 901s are my Mains.

The AVR247 has PreOuts on all of the channels.. No jumper to remove either. Just get a power amp or two and place the 901 EQ between the AVR247 and the Power Amplifier.

`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."

If you have questions not answered by the manual, you can contact customer service at The Bose Corporation in Framingham, MASS toll free at:

I have an old integrated amplifier and an old BSR EQ-3000 stereo frequency equalizer. i just bought a used bose 901 speaker set. how do i hook-up the bose 901 equalizer in this system?


Hook the signal source to the equalizer input and the equalizer output signal to one of the signal inputs on your amp. This is one way, but this way only one signal source will go through the equalizer (unless it has several signal inputs and a source selector switch).

The other way (inserting the equalizer between the preamp and the main amp) is:

If your amp has RCA connectors on the back named "preamp out" (or similar) and "power amp in" (or similar) that have slugs connecting them, remove the slugs, hook the "preamp out" signals from the amplifier unit to the signal inputs on the equalizer and outputs from the equalizer to the "power amp in" inputs on the amplifier.

Basically, what you do is that you insert the equalizer between the preamplifier section and the power amp section of the integrated amplifier so that you can still select the signal source without having to switch any signal cables (however, i can't say if your amp has got this type of "slug" connection feature between the preamp and the power amp on the rear panel, so i'm not sure which way you'll have to hook it up).

Hope you can make it work the way you want.

Compatable receiver list for Bose 901 series VI


I contacted the Customer support folks at Bose. Here is what they said: With a stereo receiver, the equalizer is run through the tape monitor section in the back of the receiver. The receiver's tape monitor output, left and right, runs to the amp input section of the equalizer, left and right. Then the amp output section of the equalizer, left and right, runs to the receiver's tape monitor input section. With a surround sound, home theater, type of receiver, the theory is the same, but the connection is through the preamp-out/ main amp-in section of the receiver. Not all receivers have this feature. Most, in fact, do not. Check the back of the receiver. There would be a connection made by two U-shaped clips. The plugs would be pulled out. Then connect from the preamp-out to the equalizer's amp input section; and from the equalizer's amp output section to the main amp-in. This effectively isolates the equalizer so that it is not affecting the other speakers in the system or the receiver's surround processing. Attached is a current list of known 901-home theater compatible receivers:
Note: Specifications subject to change without notice. Bose Corporation is not responsible for any inaccuracies due to manufacturer changes. Inclusion in this list does not indicate an endorsement by Bose Corporation. When in doubt contact the manufacturer of the equipment.

I have the list in a pdf document but do not see a way to attach it.

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.

How to connect bose 901 speakers to 5.1 setup?


The solution is simple and cheaper than you think.

The analog 5.1, 6.1, 7.1 outputs on your receiver should be active even with digital inputs that you want to hear. Your receiver turns everything it processes into analog output just before the speakers anyway so there's no loss of access to multichannel sound this way.

What I did was to buy a separate amp for the 901's and feed the Front L&R analog audio out to the EQ which is directly in front of the amp. The Active EQ is only for the 901's which don't have woofers or tweeters so Bose flattened out its final response electronically with some serious boosting at both ends. Having it in line with any other speakers would feed them a grossly over-compensated signal.

Your receiver will drive the rest of the speakers.

This is the cheapest way to have your 901's and hear them, too. Since the 901's are really efficient you don't have to buy a big amp that would heat the room. I'm using a separate Carver amp with 2x100w for mine.
