Why is the previous answer referring to VSX-36TX ? This receiver has pre out and main in capabilities- no need for external amplifier!

I have a VSX-36TX so this is how it's going to work...

You will need a separate stereo amplifier for the 901's to accomodate the need for the Active EQ. There is no way to separate your receiver's front L&R channel preamplifiers from their amplifiers.

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 and the 901's amp channels. My receiver controls everything and just drives the Center and Surrounds. You would probably just get a nice 2-channel amplier for the 901's. However, the VSX 47TX doesn't provide power for a Subwoofer, should you decide to get one, so you would need another amplifier channel for that, too. Therefore, you might look around for a powerful 3- or 4-channel amplifier so you could drive the Sub, too.

Modest amps would work but at very loud volumes may go into clipping, which is bad for any speaker. I'm using only 100W for mine and it has plenty of steam for the 901's.

For connection I would run a pair of RCA cables from the Front L&R Audio Line OUT to the Active EQ's Line IN; then the EQ's Line OUT to a separate amp's Line IN. Attach the 901's to the new amp, run through the receiver's setup procedures for volume, etc and you're done.

Not what you might want to hear but 901's have special requirements. I've had mine for 25 years and have no regrets.

A separate subwoofer channel on the amp could be used. Just run a single RCA channel from Sub OUT to one available channel IN on the amp and attach the subwoofer to it. Two would work, also. That's what I do. You could use a 1-2 RCA splitter to feed two avaailable channels on a 4-channel amp. The iterations are many. Have fun.

How to hook up bose 901 active equalizer to onkyo grand integra pre amp?


You don't.

If you have a pre-amp/power-amp combination then the Bose equalizer connects between the two. If you're using the Bose speakers as front L&R, then the connection is between the front L & R pre-out and the power amp's front L & R pre-in.

I have my bose v1 equalizer connected to my 3375 harmon kardon the following way.....equalizer(line output..to receiver tape monitor in) and equalizer (line in....to reciever tape rec output ....i am not...


I bet it would work if you listened to something 2-channel and analog. THAT is the limitation of anything that uses a proccessor (like the 901's) and modern AVR's.

Multichannel AVR's automatically disconnect digital inputs when a tape loop is activated.

Short answer from personal experience.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

The reason: You can't use the Active EQ (or ANY processor) in a tape Monitor loop with anything but 2-channel stereo material. As soon as you activate the loop you lose digital sources.

Adding to YOUR particular problem is that the 3375 doesn't have a volume-controlled pre-out to feed that amp. If you want to deal with controlling the separate amp volume manually

You COULD place some RCA Y-splitter cables where the Pre/Main jumers are and send a stereo mixdown instead of true front channel to the Active EQ and thence to a separate amp, but it's not true front channel. But you would have local control of the 901 volume after you calibrate them to match whatever other speakers you use.

When did they stop making AVR's with 7.1 pre-outs? My 9-year old Pioneer has them and I have 901's, 301's and a sub going.

I have a Bose 901 Series VI speaker system & have recently purchased a Pioneer VSX-1020-K AV Receiver. How do I connect the 901's EQ to this amp. I believe the only option is the CDR/TAPE IN/OUT...


This receiver has no pre-amp outs to drive the required separate amp the 901's need for you to continue to have multichannel digital audio. The reason: activation of a tape loop disables digital inputs. But they DID give you Front Height. Oh boy.

Pioneer vsx 1020 K receiver. I connected the bose 901 eq to the tape in and tape out but it doesn.t seem to be compatible.


It would be compatible if you ONLY listened to stereo ANALOG sources on ONLY Bose 901's. Engaging any device in a tape loop automatically disconnects digital sources. Bose Active EQ is not intended for anything BUT Bose 901's. The sub could be destroyed by it.

Lacking appropriate Front Left and Right volume-controllable pre-outs on the 1020k, you can't use the 901's for multichannel or digital source material unless you accept a severe compromise and get a separate amp for the 901's borrow mixed-down stereo from the Pioneer's Tape Out, run it through the Active EQ to the new amp and manually manage the external amp's volume.

You need Front Pre-outs.

I have a pair of bose 901, v1 I have a old pioneer vsx 5300


Not knowing anything about your specific amplifier or if it correctly configured for the 901 Active Eq, the first thing I would say is these are designed for analog stereo sources ONLY and a multichannel digital-capable receiver will NOT work properly with any devcie in a Tape loop.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.


Connect the Active EQ between the pre-outs and the amp input. Run speaker assignment, levels, etc and have fun.

Bose 901 connection to Pioneer VSX-917v Receiver


any pre-out should work. i believe the bose have a rca jack connector for attaching to the receiver. look at the new receiver connection diagram. any output that is rca designed for use by a recording device will send a signal that the 901's can see.
always check the manual on both before connecting for any precautions.
good luck
