The speakers will not sound right. You dont have two tape monitors on this receiver? You can simply use the tape otput to the EQ input, and then the Tape monitor input to the EQ output leads. Good Luck

Get a separate amp for the 901's and the rest falls into place.
1,2, 5) Place the 901 Active EQ between the pre/main front OUT of the receiver and the TFM-55X. Attach the 901's. Keep track of the jumpers you remove from the receiver. Or replace the jumpers with RCA splitter cables so you still have pre/main connection but can share the output with the TFM.
3) Pinnacle subwoofer (self-powered?) to the subwoofer out of the receiver.
4) Bose (AMS???) 5. As surrounds on the receiver. Place the sub module toward the rear so it mates sonically and directionally with them.
What? No center speaker? I'd get something more robust with bass capabilities, like a pair Bose 301 series 1's because the tweeters face in one direction only.
Except for the amps and the cube stuff that is essentially what I have. 6.1 with full-range speakers everywhere.
As far as I know, any equalizer will work. There is a guy on here that might know more about them, but I never had the Bose equalizer and I have Bose speakers for 35 years. The guy at the electronic store back then sold us a little equalizer at first, we graduated from that a long time ago, and now on the 3rd or 4th one. No problem, works great, sounds better than ever. Hope this helps.
You want them to be your Main Front speakers, right? The news is not good. There will be some limitations because you can't extract 'processed' L-R from this receiver. The following will give you good stereo and Front L-R from the 901's but it won't allow central volume control or send them any of the DSP effects you may select. Sorry. If it had a Front L-R Pre-Out you'd be good to go for all functions and listening modes. You'll need a separate stereo amplifier WITH ITS OWN VOLUME CONTROL for the 901's to accommodate the need for the Active EQ. 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. With this receiver we have to cheat to get the Front L-R signal out to the 901's (but it's unprocessed and at a steady volume level)... For connection I would run a pair of RCA cables from the VCR/DVR Audio Out L-R OUT jacks (*) 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. * You'll lose the ability to use these jacks for anything else, but few of us use them anyway. DO NOT select this function for monitoring or you lose all audio in the Onkyo.
There is no direct connection between the 901's and their Active Equalizer. It is designed to be inserted between the source and the DEDICATED amplifier driving the speakers. Typically, this would be in a Tape Monitor loop on a receiver.
Tape Rec/Out to EQ In; EQ Out to Tape Play/In on the receiver. If you have a tape deck(s), it(they) would go into the back of the Bose EQ as if it was the receiver and you would use the Tape and 1/2 buttons for selection.
Or,if you have access to any other point that doesn't use the Tape Monitor, like a Pre Out/Main In jumper set, place the Equalizer there. That way it's always in front of the speakers and doesn't take up the Tape Mon.
Flip in the Tape Monitor and leave it on or the speakers will not receive the essential ACTIVE Equalization they require for proper frequency response. DO NOT place non-901's onto any amp using the Active EQ.
Like any speakers, the 901's will attach to the speaker terminals in the conventional manner.
The good news. I have a setup similar to what I think you're trying to do and it works great!
The Onkyo M-282 stereo amp for the 901's is the perfect solution. Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.
**Onkyo SR805 Pre-Out Front >>> Bose EQ Amplifer IN
Bose EQ Amplier OUT >>> Onkyo M-282 IN
Set the Input Level on the back of the Onkyo to MAX. The receiver controls everything just fine after you run through your level setup routine again.
I was looking a the 12v triggers on both units and it looks like you only have a Zone 2 trigger so that wouldn't work for turning on your M-282. I guess you're going to have to turn it on and off the old fashioned way, like I do mine.
I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.
There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.
The good news. I have a setup similar to what you want to do and it works great! I see on the SR875 there are Pre Audio OUTS. This is easy.
A separate stereo amp for the 901's was my solution. 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 Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.
You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.
** Front Pre Out >>> Bose EQ Amplifer IN, then Bose EQ Amplier OUT >>> new amplifier IN.
Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.
