The use of 901's 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.
That is because 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. However, you can still draw the Front Left and Right signals out of any Pre-Out (with a Y-cable set, looping the Pre Out directly back to the Main In) or Tape Out jacks (remembering to NEVER activate that monitor on the receiver), go into the Active EQ's Amplifier Connections; then Out of the EQ's Amplifier Connection to a separate amp and attach the 901's to that amp. This way you won't 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. 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.
The AV Receiver can still drive the Center, Surrounds and the Sub(s) as it is designed. This is how mine is wired.
Come to think of it, you could still have conventional Front L&R speakers on the AV Receiver, but why? Maybe one would prefer the 901's for music and some other speakers for surround. Level matching with the 901's to conventional front speakers would only be possible if the separate amp has its own volume, but it would work. Maybe I'll try it someday. None of my current amps has a volume control.
Hi
I have got exactly the same problem with an Onkyo amp, i have connected it up but there is no difference. I also do not have a tape monitor on my amp!
Email me at [email protected] if you want as I have read a few solutiotns and would be also interested on if you got yours going ok
I'm not sure that receiver is compatible with outboard EQs like the 901 EQ. This receiver is also not on Bose's 901 EQ compatibility chart, so it's possible that this is not going to work at all. You could call Pioneer and ask if this receiver is compatible with ANY outboard gear (such as EQs, compressors etc) but I don't think it is.. The tape in/ tape out I think is only for 1 source.. That's the problem with new receivers, they expect that nobody will want to connect any external gear (like back in the day) because everything is built in.
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.

Here is what I did- I purchased a 4 input A/V switch, then I connected each one of mycomponents to the inputs (just the audio plugs) to the switch, then connected the Bose 901 EQ to the output of the switch (output of switch to input of eq) then output of EQ to input of my receiver (I chose TV/DVR input. Now I just chose which componet I wish to listen to, and bang! works like a charm! The only downside is having to get up to manually push the selector switch! Sounds great. Hope this helps.
