Question about Bose 901 VI Main / Stereo Speaker
Has pre amp and was connected before but need to figure out how to reconnect ...
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.

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.
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
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...

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.

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.
