Question about Onkyo M-282 2-Channel Amplifier

1 Answer

I've got an Onkyo M-282 with one channel that just died. Upon visual exam, there seems to be absolutely nothing wrong with it (the caps are all flat, not puffing, no broken components or smells...).

It doesn't have a fuse protecting the speaker outputs. Also upon first inspection, I had to do a reset as the standby light was staying red and flashing. When the reset was done, the standby light went yellow and I got sound from the left side.

Is power coming out of transformer at the right voltage. Also may have a power i.c. shorting to ground.Final anp i.c. may have a place to go to ground through a shorted capacitor.
GOOD LUCK

SOURCE: i have 1 center channel

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..

check your amplifier output speaker impedance requirements..
example: 8 ohms...build a speaker 8 ohms in parallel or series connection..
check the impedance using ohmeter ..you must reach the required impedance..

use 1 cell battery to check if you speakers are in-phase...if one speaker did not ..reverse connection and check again ...to give the good sound...hope you understand my english..:)

If your speakers are not in good condition you may have floated the cones inducing DC feedback into the amplifier, Im not sure if this amp has internal protection fuses, but I would check them and if so replace with same specification fuses. Sometimes we get lucky... Good luck

Bose 901 hookup with Onkyo SR 805 and Onkyo M282 amp and 901 EQ/


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.

ONKYO M282 AMP seems to have lost all mid and low range


It's probably salvagable but I doubt it will be cheap or easy. Most likely you have one or more ruined output transistors. If you're into taking things apart and soldering, it might be easy for you. Just look
for abnormalities on the transistors, usually a little hole in the center of them or blistering. Replace those and you'll either have it back to sounding good or much closer to it. Most output transistors do not fail without showing visual evidence of it.
