5.0 out of 5 stars outstanding 2-channel amp, September 18, 2007
Verified Purchase(What's this?)
This review is from: Onkyo M-282 2-Channel Power Amplifier (Discontinued by Manufacturer) (Electronics)
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.

Note that unlike several other reviews here, my unit did not get very hot - certainly far from the heat generated by my Sony ES receiver. Nor did I experience a 60Hz hum when the unit entered standby.

Finally, although some reviews say this unit has been discontinued, it still appears on the official Onkyo web site, and availability seems good. So I would say it's not discontinued.

In summary, this is the "perfect" 2-channel audio amp - highly recommended without reservation. And an unbelievable value for near-audiophile performance.

can the 2 outputs be driven at the same time, i.e. combined?
