I have 1 center channel pre-out on back of my kenwood receiver. how do i hook it to the inputs on onkyo m-282 amp and then to center channel speaker?

If you have audio out jacks from your tv, you would be better served hooking that up to the preamp. If you hook up the blu-ray player separately to both the tv and amp, the audio probably will not sync with the video correctly. The tv takes longer to decode the hdmi input and the audio will be ahead.

If you receiver has tape monitor outputs, you can hook the sub up to those.

your receiver must have a pre amp out on the back.

called onkyo and kenwood they explained in detail how to hook up.

If no Amp is used, connect jacks ( Left, Right) from your receiver output to Bose equalizer Input ( L, R) where it says Amplifier. Then also under where it says Amplifier, connect jacks from Output to your speakers. This would require the type of speaker wires that are RCA (plug in, red and white) on one end bare wire on the other to the speakers.
I don't know what the output is on your Kenwood, but if it's low watts, an amp is much better to crank those Bose. It's a different connect with an amp. Go L &R from the receiver to Equalizer as before, then from equalizer to amp Input where it says Tuner. then hook bare speaker wires to back of amp to Bose speakers.
You should have full use of Bose controls. The Monitor button is for an extra component that can be hooked up on the back, right side of equalizer.

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.

Sounds like classic dry joint on speaker terminal ROTELS are well known for it,if you can use a soldering iron or know someone who can resolder the pins where these terminals are connected,always make sure amp is unplugged from wall socket before ...

AV receivers are notoriously incompatable for Bose 901s. The problem is the EQ charges the entire system and could damage the surround processor. Some higher end AV receivers, including some of the newer Onkyo models have pre out power in inputs on main or all seven channels.which you could install your EQ directly between pre amp & power amp without damaging processor. You can also add a two-channel amplifier to the pre out jacks front channels and use your recever's remote to control volume.

i may can help><><><<<<<<<><><>,a receiver is basically use for the house and a amp is for dl applications or other events that require more sound.,.,.,i see you hung up on onkyo.,,.,i never heard of until now.,.,,,,,.but all amps mainly have the same diagram or layout.,.,.,.,you miver plugs into your amp.,,.,.it should have a left and right input some have rca hjacks others have 1/4 inch.,.,,some have both.,,.,.,.,.but plug your connector into your amp from your output mode on the mixer.,,to the amp inputs.,,thats all you have to do,.,.,,,connect your cd plugs to your line in of your mixer.,.,.,.,its really simple.,,i reccommend that you get a cd (dual)player thta has its own mixer built in.,,,that way your connections will be simple
