In a nutshell, the controller would go between a preamp Stereo OUTput and a dedicated amplifier INPUT. You can't use Bose 901 or 802 EQ in a multichannel setup without separate amps for the Bose speakers.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.

In a vanilla stereo configuration you would just put the controller/EQ into a Tape Monitor loop but multichannel sound and digital sources won't work that way.

You should be able to draw off the (assumed) Front L&R channel preamp signal from the MD/CD-R or DVD-R Audio Out (REC) jacks (*). Run that to the Preamp In (or whatever it's labeled on the Bose EQ/Controller). DO NOT run a return RCA pair back to the Receiver as Bose-processed signals will not play well with non-Bose speakers. (*) Run the Output of the Bose EQ/Controller to a powerful separate amp for the Bose 802/901's. I use two channels on a Carver multichannel AV-406 amp but a stand-alone Carver MT-200T also works well. A good clean 100 watts/channel should suffice at home.

* If possible, choose the recorder loop you are NOT using for something else. If you're using the MD/CD-R or DVD-R Audio OUT for a recording device just get some RCA splitters to share the Stereo signal between the Bose and the device at the same time. However, once you select monitoring of that recorder two things will likely happen - 1) you'll lose the Bose and anything digital in the receiver will be disabled.

It's the nature of the digital beast that analog monitoring gets in the way of DSP.

Of course, if anyone who reads this has a receiver with individual analog Audio Outputs for the various 5.1 channels (as I do), the solution would be to draw off the Front L&R channels to the Bose EQ and downstream amplifier and the rest would be the same but without Recorder Loop limitations.

How to connect my Bose 901 series vI speaker to yamaha rx v740 and rotel rb 1582. Appreciate your help. Thanks


The Bose controller gets wired in series between the pre-amp and the power amp.

I presume you plan to use the 901's as the front L&R pair. So the cables going from the 740's Pre-Out Front L&R go to the inputs on the Bose controller. The outputs of the Bose controller go to the power amp Front L&R channel inputs.

Loud hum when Bose Companion 3 Series II speakers are turned on.


I had the same problem for many months. I asked a sound & video professional and he suggested I move the subwoofer away from any power source. I had the subwoofer next to my UPS. Once separated and moved all wiring away from the power supply (about 12") the low bass hum was practically gone.

In a nutshell, the controller would go between any preamp Stereo OUTput and a dedicated amplifier INPUT. You really don't have much choice in the matter. The 802's and their controller are part of an inseperable system.

The Bose 802/901 family uses full-range speakers instead of traditional woofer/tweeter combinations, so they compensate for the response limitations at the extreme frequencies by using severe electronic modification of the program material. Hence, they are a system, functionally inseparable, but the results are outstanding. Consequently, they need a dedicated amplifier so they alone get the processing provided by their electronic component.


I don't have any data on your mixer/amp but if you can't insert the conroller logically between the mixer and its amps then you'll have to get separate dedicated amplification for the 802's, with the controller between the mixer and that amp.

What kind of amplifier and other accessories are recommended for bose 901 speakers


I would recommend a high power 2-channel amplifier, minimum 16 guage speaker wire, and of course the Bose 901 active EQ that matches the series of your speakers. I use a Yamaha mx-830 power amp & cx-830 pre amp 170 wpc They (Bose) claim that they're unlimited power handling, But if you use a amplifier with to little power and overdrive it to make it louder, you could damage the speakers or amp. With my 170 watt class A amp,the 901 series 6 will blow wind across the room. Go with the best amp you can afford! best for money- Yamaha,Denon,Onkyo!
