If you're going for an upgrade from 5.1 to 7.1, make sure your 5.1 surround receiver has preamplifier outputs for 7.1 channels. The M-282 only amplifies a line-level signal; it does not include surround processing or a volume control like a traditional preamplifier or an integrated amplifier/surround receiver.
You can rig the amp to power up when it senses an audio signal or through the use of a 12-volt trigger (standard to automation systems). The receiver also features audio passthrough jacks in case you want to daisy-chain several like components through several rooms for multi-room distribution of your primary listening source.
The receiver uses Onkyo's Wide Range Amplifier Technology (WRAT), which ensures signal accuracy even with high-resolution sources such as DVD-Audio and SACD. According to Onkyo, WRAT eliminates the adverse effects of counter-electromotive force by applying an unusually low amount of NFB (negative feedback), constructing the amp with carefully selected, high-tolerance, wide-range parts in all critical sections, and using innovative circuit topology based on the company's decades of experience building high-end amplifiers. The result? A flat response beyond 100 kHz.
Rear-panel connections and controls consist of a ground (use only if the system exhibits an audible hum), an input-level adjustment, 1 each stereo analog (left/right) RCA audio input and passthrough/output, a trigger setting (audio, 12-volt, off), a 12-volt trigger input jack, left/right speaker outputs with banana-plug-friendly binding-post speaker terminals, and a grounded AC power terminal.
What's in the Box
Power amplifier, an AC power cord, and a user's manual.
If so, I will consider this purchase a screaming deal.
The sound is clear and clean, no hum, or hiss (from the speakers, see the bad) It makes you understand why you spent 10 times as much for your main amp.
I have been a fan of Onkyo for quite some time now and this M-282 only redefined my love for the brand!
Quiet. Easy to forget it's there except for how much you love having bought it. A brief look inside through the grated top shows simple and high quality engineering.Published 8 months ago by Tim Perfetto

just like the man said it work very well it pushes my j b l l L5 very well i always used carver or adcom amps before twice the watts per channel it fills the room with clear... Read morePublished 13 months ago by tim adkins
The Onkyo M 282 2 channel power amplifer is a good amplifier that is easy to install and works well with my Niles speaker switch. Read morePublished 18 months ago by Shredder
Added this to drive my outdoor speakers and used a splitter for all the zones.
This worked great, I would recommend this product.
Great amp, lots of power, needs volume control on the front of the unit. Volume control is on the back of the unit.Published 23 months ago by Ed Cary
Unfortunately I had to send it back because it was damaged in shipping. I tested the amp on my system and it seems to function ok. Read morePublished on March 11, 2013 by @Mead57
Matched this unit up with the Onkyo 818 AVR. It runs my front speakers easily and sounds very nice. I am happy with the amp for the price.Published on December 24, 2012 by grpape
