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 can I connect an analog turntable to my Pioneer VSX-D710S? Also, do I need a turntable with a built in pre-amp?


According to the specs there aren't any phono inputs which would have their own preamp. Everything else is line level so I'm pretty sure you'll need a preamp either between the turntable and one of the line level inputs or built into the turntable.

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.

I'm connecting Bose 901 speakers with an Active Equilizer hookup required to my new Pioneer VSX-520. What in/out puts should be used ??


The solution to using 901's in a multichannel rig works best when you have individual Front Right and Left Pre-Outs but this receiver doesn't have them so a compromise is in order.

First some background.


The use of 901's Active EQ (or any external processor) 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.

This works for all models of AV receivers when you want 901's as Front L&R speakers...


Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them, in your case maybe the CDR or DVR/VCR outputs.


On many AVR's, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others (yours), you have to borrow the signals from a typical CDR or DVR/VCR Output RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won

I want to connect a pair of Bose 901 speakers to the VSX and use them as my front speakers powered by a separate amplifier but can't find an appropriate pre-out from the VSX.......what analog VSX output...


It doesn't really have one. The DVR-Out (or any other available Line-Out) COULD provide a mixed-down analog stereo program but it won't be volume controllable from the VSX and it won't be Front-Channel specific. Sorry.

You would then connect the EQ between the chosen Line Out and the amp input. If you had a Pre-Our you would just run speaker assignment, levels, etc and have fun. With a Line Out feed you will have to ride herd on the 901 volume via its dedicated amp controls. Bummer. My older VSX-36TX allows me to have the right setup.

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.

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.

How to install bose 901 eq to my pioneer vsx-1019ah-k


This works for all models of AV receivers when you want 901's as Front L&R speakers..

Get yourself a nice separate amp, draw the Front L&R pre-out signals from wherever you can find them. On many, there is a pre-amp out for every channel in case you want to run external amps for any channels. That is how my old Pioneer VSX-36TX is equipped. For others, you may have to borrow the signals from a typical Tape- or Adapter-Out RCA pair. Just remember, AV receivers disable digital inputs as soon as you switch in a Tape Monitor, so choose one you won't have to switch IN. The signal Out is always there regardless of the monitor state.

Patch the Active EQ directly off that point (Amp In from the receiver, Amp Out to the new amp). Run all the speaker level settings on the AV Receiver and rock on.

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
