Product Description

Product Description

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. 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!

I bought this amp to drive a passive homemade sub and it has done nothing but please me. I'm running it at 4ohms to each channel, and it pumps out serious power. Despite the lower resistance, its heat dissipation is lower than my receiver. I do not believe Onkyo's numbers for this amp, they have to be higher. When I hooked it up to my main front speakers, it revealed an exellent range of frequencies at any volume. This piece is a great example of Onkyo quality for a low price, I'm still curious as to why they discontinued it.

I bought this 2-channel amplifier to drive a pair of in-ceiling speakers in another room. For my application, this amp is perfection. I'm certainly glad I didn't buy the similarly-priced but much-less-powered unit from Audio Research.

The output power is phenomenal - noticeably stronger than the 150w per channel output spec from my Sony ES reciever. Either Yamaha is being conservative or Sony is misleading. The sound quality is very clear, low noise, and free of distortion even at loud passages. Frankly I'm stunned at the performance for this low a price point.

This unit is beautifully finished, and looks at home with the rest of my components. It's actually smaller than I expected as well. The front of the unit has a hard power switch, and a standby/on indicator that is red on standby (soft power off) and orange when on.

The rear of the unit has a 2-channel RCA input, a 2-channel RCA output (passthrough), one set of speaker connectors (accepts banana-type and wire), a 12v trigger input, and the power cord input. There is an input level adjustment (essentially a volume control) but in my application, I found it best to set this at maximum volume and let my in-wall volume control adjust the level. There is also a switch to control auto-power settings: disabled (power is controlled by the front switch), audio (front switch remains on, unit changes from standby to on when audio signal is detected), and 12v (external 12v trigger). There is quite a long delay from power-on to on, and in my setup, I chose the OFF mode - where I turn the unit on from the front when I want to use it. The supplied power cord is quite hefty and probably overkill.

I was looking for a "cheap" amp to drive my 2nd zone "background" music speakers. My price point was around $200 and this unit has a good look to it, so it would fit in next to my more "up scale" B&K separates.

The Good:

It came double boxed and packed well, (always a good sign).

It has a hi-end look to it, (good fit and finish).

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.

The Bad:

The thing is a space heater even when in "stand by" mode the heat is coming from the inexpensive power transformer.

The two tone LED is red when in "stand by" and a cheap orange when "on" I guess green or blue would be better for "on" for me.

I found that when I turned everything "off" to go to bed the transformer has a 60Hz hum to it that can be heard if you are standing a few feet away.

Conclusion:

It seems like a good amp, and if I compare it to the price I paid for my B&K amp it is a good value. Time will tell if the "budget" components will hold up over time. Because of the heat and hum from the transformer I would suggest not using this unit as part of your main music or surround system. I was going to give it 4 stars for looks and features but the heat and hum drag it down to an average 3.

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. I solved the problem with this Onkyo power amp in combination with a pair of Polk Audio Monitor 40 2-way bookshelf speakers. The audio output of the TV is fed into the RCA-type audio input of the Onkyo amp. 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. The resulting sound is much better than the low-fi sound from the TV's built-in sound system -- richer and better defined. The Onkyo amp just sits on a lower-level of the TV stand; I don't have to do anything with it. 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. When I turn the TV off, the amp returns to the idle mode. It's as though the Onkyo power amp were built into the TV. I don't detect any noticeable hum from it, and it does not generate excess heat, as some reviewers complained about. For my rather basic needs, this is an ideal solution. I am totally satisfied with this Onkyo power amp.

Onkyo M-282 2-Channel Power Amplifier
The reviews by others of this product helped me decide to try it out, and I'm glad I did.

I've had a Carver 0.5t "Magnetic Field" High Current 2-channel Power Amp since 1988; serious power (220 RMSw/ch into 4 ohms....140RMSw/8 ohms)..driving my MAIN LEFT and RIGHT Front HT loudspeakers. And this was power back-in-the-day, when audio manufacturers followed "the rules"; disclosing continuous power into all channels driven, into a nominal impedance, over the entire audible frequency range, and specifying the THD applicable to all this as well.

The Carver was great.....that is, until it gave up the ghost a few weeks back! I was highly upset, but I did REALIZE I got 20 years outta the thing; you can't say that about a LOT of the consumer electronics being sold nowadays! Carver's been long gone...& even when they were STILL AROUND and owned by someone besides Bob Carver, the quality went down the hill...so I figured a worthy replacement would be some high-end esoteric amp...way beyond my budget.

I started searching and found good reviews on the Onkyo M-282, and I know Onkyo makes some high-quality Home Theater Receivers...but being a separates man..a HT Receiver was out of the question. So I ordered the product, it arrived a day earlier than expected, and I must say, it performs extremely well....considering the price.

Admittedly, I've gotten used to the "warmer" sound of the old Carver amp, but the M-282 does bring out a few details (with the same loudspeakers), and it essentially pumps out the same quality and quantity of power as the Carver...
