Bose 901 Equalizer connections to Harman Kardon AVR520

Would you kindly tell me exactly which connections on the back of my AVR520 for the equalizer in/out? Thank you.

    I have the same problem. I have connected the Bose 901 speakers to Harman Kardon using the Bose Equalizer. Howvere, I have connected the Bose to the FL and FR channels - however, it seems that the other channel sound gets filtered out. Can/ Should I connect additional speakers to other channels? If yes, how can I find compatible speakers?

I wrote 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! With one caveat - My receiver actually has 5.1 analog Outputs so I can drive up to 6 external amplifiers if I want to (I drive 4). IF yours does NOT (*) we have to be creative in extracting the front two channels from your multi-channel receiver. The obvious alternative place would be at one of the few OUTputs on the back, assuming you have one free to use.

If your receiver has Pre Audio OUTS so I'm betting your receiver does, too.

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 VCR or Tape Out if you don't have Pre 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.

*** If you use a Tape or VCR Out you will NOT be able to SELECT the source you use for the 901 Pre-Outs for listening, or else the 901's will not get any sound sent their way. DO NOT USE the monitor switch for that source.

How can i hook-up a 901 series vi equalizer to a str-de897?


I own 901's(since new) with the active equalizer powered with a non-Sony surround sound receiver.

Basically, you use the MD/Tape in/out jacks to route the signal to the Bose active equalizer. Switch the Tape Monitor switch if no sound is heard.

Here are some references.
https://docs.sony.com/release/STRDE897.pdf http://products.bose.com/pdf/customer_service/owners/901_guide.pdf

Connect equalizer cables (4 total) to the MD/TAPE section of your receiver. OUT from the receiver to the equalizer IN and Out from the equalizer to IN on the receiver.

One issue with the equalizer running through the MD/Tape jacks is that it may affect any other speakers hooked up to your system.

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.

I have Bose 901 series 5 and would like to hook them up to HD Tv with AE receiver. Can I do this and what kind of receiver do I buy? Thank you Chis


I assume you mean you want the 901's to be part of a multichannel audio system as the front speakers. Your controlling electronics will dictate how the 901's integrate.

The following is general high-level advice to get you on your way. I have 901's in my 7.1 A/V room, so it CAN be done.

Bear in mind that 901's require exclusive use of any amplifier they use. You shouldn't expect to use conventional speakers alongside them on the same amp.

The reason is that the 901's require the use of their dedicated Active Equalizer to shape the frequency spectrun to match their drivers' response curves, resulting in a flat sound output. Applying that kind of equalization to any conventional speakers will sound to sharp at the extremes and may even potentially damage them.

If your rig has Pre-Outs for the Front L&R channels you're in luck. Just task them to through the 901 EQ to whatever amp you choose to run the 901's on. Set levels and you're off and running.

If no pre-outs, it gets complicated and some compromises will need to be made. Get back to us on what your control amp/receiver is and we can continue this - or search Fixya for 901 advice. I have written a ton of these for people. One may fit you perfectly.

How do I connect my 901"s to my amp "NAD" 7600 power envelope ?


Bear in mind that 901's require exclusive use of any amplifier they use. You shouldn't expect to use conventional speakers alongside them on the Speaker B terminals. The reason is that the 901's require the uyse of their dedicated Active Equalizer to shape the frequency spectrun to match their drivers' response curves, resulting in a flat sound output. Applying that kind of equalization to any conventional speakers will sound to sharp at the extremes and may even potentially damage them.

You can use them in either of two ways.

Attach the Active Equalizer in your Tape 2 loop, following the clear guide printed on it. Activate Tape 2 to place the EQ in line with the program. Bypassing Tape 2 would show you what 901's sound like without their custom EQ curve. NEVER set the Copy function to 2>1 as this would introduce 901's EQ to whatever is on Tape 1.

or (recommended)...

TO preserve the use of your Tape attachments (through which you might also run any other kind of sound processor), remove the jumpers between the Pre Out and Normal In and attach the Active EQ there.

Should you anticipate using this rig in a multichannel setup from an AV receiver, just draw the AV receiver's Front L&R out from its Pre Out connectors, or from one of its Tape Out connectors, and into this amp's CD or Video Sound inputs. You would still have the flexibility to use the NAD for your Stereo-only rig, and your AV receiver's stereo sources would be available to it, too.

This is essentially how I run my 901's as the main speakers in my 7.1 home theatre.

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.

Hi, I just purchased a used set of 901s with the original active equalizer. they are both series VI and were bought together. Unfortunately, the man misplaced the installation instructions for the...


If no Amp is used, connect jacks ( Left, Right) from your receiver output to Bose equalizer Input ( L, R) where it says Amplifier. Then also under where it says Amplifier, connect jacks from Output to your speakers. This would require the type of speaker wires that are RCA (plug in, red and white) on one end bare wire on the other to the speakers.
I don't know what the output is on your Kenwood, but if it's low watts, an amp is much better to crank those Bose. It's a different connect with an amp. Go L &R from the receiver to Equalizer as before, then from equalizer to amp Input where it says Tuner. then hook bare speaker wires to back of amp to Bose speakers.
You should have full use of Bose controls. The Monitor button is for an extra component that can be hooked up on the back, right side of equalizer.

Bose 901 series speakers to Bose 901 Equalizer


There is no direct connection between the 901's and their Active Equalizer. It is designed to be inserted between the source and the DEDICATED amplifier driving the speakers. Typically, this would be in a Tape Monitor loop on a receiver.

Tape Rec/Out to EQ In; EQ Out to Tape Play/In on the receiver. If you have a tape deck(s), it(they) would go into the back of the Bose EQ as if it was the receiver and you would use the Tape and 1/2 buttons for selection.

Or,if you have access to any other point that doesn't use the Tape Monitor, like a Pre Out/Main In jumper set, place the Equalizer there. That way it's always in front of the speakers and doesn't take up the Tape Mon.

Flip in the Tape Monitor and leave it on or the speakers will not receive the essential ACTIVE Equalization they require for proper frequency response. DO NOT place non-901's onto any amp using the Active EQ.

Like any speakers, the 901's will attach to the speaker terminals in the conventional manner.

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.
