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?

Unfortunately can't connect it that way. The pre out is only meant to go directly into an amplifier that has all of the same inputs (front/rear, center and surround), not a standard receiver. (Pre amp to amp only, not pre amp to receiver) If your Onkyo doesn't have all the same inputs as your Kenwood preamp has outputs you will just use your standard left/right outputs from the Kenwood to your Onkyo input (CD, Tape, Phono,DVD etc) then use the outputs (front/rear, center and surround) from your Onkyo receiver and connect directly to your speakers..

Purchased 2 used sonance sonamp 260 for homewide speaker system (12 pair).line out from receiver into first amp powering first 8 pair.line out from first amp into second amp powers remaining 4pair.only...

I am assuming you are using the standard sonamp 260 not a 260x3
and that when you say you are getting sound on only 1 pair that means only on 1 side (left or right channel only?)

Are using a speaker selector box? you must to regulate the resistance (ohms)

if so first unhook all but on pair of speakers and see if both channels are working.

if they do your problem is in the speaker selector not the amp if no then check to see what the amp level is set to. These are the two small holes on the front right of amp make sure they are set about equal at around half way up.

If that doesn't work flip the RCA cables coming to the amp perhaps you have a bad cable if that doesn't work make sure your receiver (source) is outputing a stereo signal to begin with.

lastly 8 sets of speakers off 1 amp? that's pushing it.even with a high quality Niles or speakercraft selector that controls the resistance going to an amp I wouldn't go past 5 sets.

The right way to do it would be to use 260x3 or a sonance or speakercraft 12 channel amp.

I would like to know how to connect my Bose 901 to my Yamaha RX-V765 AV Receiver.

Ahhh, the good ole Bose 901. (I like those)... And you want to connect them to the Yamaha RX-V765 AV receiver. That should be a piece of cake. I assume you only have two Bose 901 cabinets. If so, you simply need to connect one end of your speaker wires to the terminals found on the 901 cabinets, and the other end of the speaker wires need to go to the Front Left and Front Right speaker outputs of the RX-V765. The RX-V765 is a 7 channel surround receiver. Weather you run it as a 7 channel theatre or as a more classic 2 speaker configuration, you will want to run the 901 cabs from the Front L and Front R speaker outputs, unless for some reason you want to specifically use them for any of the surround channels in which case it will not harm anything if you use them for surrounds - it's just that if you're simply wanting to use them as your principal speakers, you want Front L and Front R.
So connect them as I explained, power the receiver up, put on your favorite CD and enjoy!

How do i bi amp sx 1250 to get both channels of each side to work together

you are actually not bi-amping the unit, you are bridging the amp. this really only works as long as all channels produce equal power. next the bad news is that typically home stereo amps are not wired internally to bridge channels.

bi-amping a speaker refers to connecting on channel to the highs and on channel to the lows. the receiver would need to be be able to process the outputs via a crossover network to split the frequency range in half so the appropriate frequencies went to the correct speaker.

I have a question first... are the 901's amplified by a separate amp as they should be in a multi-channel (non-stereo) setup?

Better yet read the following then decide if you have iy set up right to begin with. If so, I'd just treat the Ipod or Mac as auxilliary inputs on the receiver. :

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!

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 (or one of your analog Tape Outs) >>> 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.

Write off the Tape Out as an input if you use it to extract the Front L&R channels. DO NOT monitor it or you'll chop the 901's out of the signal path AND kill any digital source audio in the receiver.

My amp has lost sound in one channel.I need a circuit diagram.

No you don't really. The good channel will tell you everything about the bad channel as it should be the same. For instance you can measure voltages and compare them and if you prod the good channel and get a loud buzz at various stages. Then you should also get the same results with the bad one. Work backwords from the speaker terminals. Buzz on good Buzz on bad section is working. Buzz on good nothing on bad. Faulty stage. It's not likely to be the power supply as that would affect the other channel.

? connecting AudioSouce amp two to my receiver

if you're using the receiver as a preamp, you'll need a low level output on the receiver which tracks with the volume control on the receiver. Some receivers have "preamp out" jacks which are tracked with the volume control on your receiver. This is what you're supposed to use. However, if you don't have this feature, you can use the headphone jack on your receiver. This is what I do with my amp and it works great!

I receive a radio channel in one of the outputs of the preamp

I would use sheilded wire on the mic with the least amount of cable. You can relocate the pre amp with aluminum foil wrapped around the pre amp. also turn the gain on the mic down as to eliminate any interference from your strong radio station nearby. Randy
