Ideal for quality stereo listening, for expanding your surround system from 5.1 to 6.1 or 7.1 channels to deliver the latest home theater surround formats, and for multiroom setups, Onkyo's M-282 stereo power amplifier makes a powerful and affordable system upgrade. The amp uses Onkyo's exclusive Wide Range Amplifier Technology and pumps 2 x 100 watts per channel RMS into 8 ohm speakers and 2 x 125 wpc into 6 ohms. (For dynamic power handling, you're looking at 2 x 140 watts into 8 ohms, 2 x 125 watts into 6 ohms.) 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.

Onkyo M-282 2-Channel Power Amplifier Reviews
About the only thing I didn't like about my 40-inch Sony LCD HDTV (KDL-V40XBR1) was the undistinguished sound of its built-in speakers. The audio output of the TV is fed into the RCA-type audio input of the Onkyo amp. The resulting sound is much better than the low-fi sound from the TV's built-in sound system richer and better defined. I solved the problem with this Onkyo power amp in combination with a pair of Polk Audio Monitor 40 2-way bookshelf speakers. I am totally satisfied with this Onkyo power amp.
It's as though the Onkyo power amp were built into the TV. I set Onkyo's volume control (placed on the back of the unit) about a half-way point, and control TV's volume with the Sony TV remote. When I turn the TV off, the amp returns to the idle mode. I don't detect any noticeable hum from it, and it does not generate excess heat, as some reviewers complained about. The Onkyo amp just sits on a lower-level of the TV stand; I don't have to do anything with it. For my rather basic needs, this is an ideal solution.
My black Onkyo unit is almost invisible. When I power up the TV, in a few unnoticeable seconds the Onkyo amp's IDLE mode changes to ON mode, and the sound comes out of the Polk speakers.
I use it with a pair of Infinity Beta 20. The sound is clear, neutral and has plenty of power. It may sound a little expensive for an amplifier, but I believe it has excellent value. I have been using this amplifier for more than 3 years and it has always provided excellent results for me.
I needed a "new" amplifier that wouldn't break the bank. I am tired of buying used equipment to save a few bucks initially, only to pay for repairs soon after the purchase. I didn't notice any hum from the power supply. Hopefully, this amp will run for many years without problems. I was afraid the amp might be too bright, but no it was quiet flat. If so, I will consider this purchase a screaming deal. I just used this amplifier for one day but I must say that it certainly fulfills the need. This amplifier sounds good.
It certainly is no giant killer, but it does sound better than any "classic" equipment that costs a couple of hundred dollars more. The sound is balanced. There is plenty of power with 100 watts per channel. I am thinking that the people who experienced hum may be getting it from their AC lines.
Binding post do not Accept spades: This is true of most Reciever/amplifiers. Between the two the Onkyo runs hotter. Just make sure you give enough air flow. Normally, I only use it to drive one pair of speakers at a time but at times I have driven both pairs for extended periods of times. I do have the amp in a cabinet with 8" of clearence and that seems to be good enough. Here are a few observations:. I have an Onkyo and Marantz Home theatre reciever.
I do not hear it. This amplifier is no different. FYI: by extended periods of time I mean 8-12 hours. I use this amp to power two pairs of outdoor speaker via a impedence matching speaker selector (Monster Cable SS-4). I prefer spades to pin, bar wire or banana connectors. I also have a Onkyo home theatre reciever and I observe no hum through that either. It does the intended job without a hiccup.
Overall, I am very happy with the amplifier. This could because the amplifiers drives outdoor speakers (where there is more ambient noise) or due to "dirty" power or poor cables. Hum: I read a lot of reviewers complaing of a hum. Read both proffesional and amatuar reviews on both Onkyo and Integra. Runs Hot: This is a characteristic of all Onkyo amplifiers. I do use a votage regulator and line conditioner and all my cables are by cobalt cable.
But then thats what the pre-amp is for. I have installed two of them as additions into friends home setups over the last couple of years and both are working great. For this price it can't be beat. I haven't had the same issue with it taking a long time to turn on after being in standby. One is paired with a Yamaha receiver and operates off the 12 volt trigger. Only gave it 4 stars because of the lack of tone controls.
