Really good clean class B power. I used this bad boy to power a pair of Klipsch 500sa up firing Dolby atmos speakers and it works great! It has built in rack wings in case you were to install it in a media rack which is not removable permanently on the amp and this amp is not bridgeable which is my...

I am a physicist. (energy physics not matter physics). I am also a sound engineer, coincidentally, the control of sound energy. This amp is VERY GOOD for bench testing audio control devices and speakers. The addition of an unbalanced input makes it very handy for typical bench tests.

Great device, easy setup. Good true sound produced by the amplifier. The only little thing is that if you put out a low volume, you hear the cooling fan running.

This amp sounded great, and produced just the kind of power I was looking for. My only issue with it was that the fan is really noisey, if you have a sound proof cabinet you will be fine but if not, this amp will distract you

This amplifier has the power and quality I was looking for.It is also much lighter than the old amplifier that it replaced.

Bought this to replace an old amp with a bad channel. Used for overflow speakers in our church lobby ceiling. Inputs and outputs were totally compatible with our system's existing wiring, making it a simple hook-up. It worked perfectly right out of the box.

As noted in other reviews the fan is a bit noisy. In my case that's not a big deal as my amps & other equipment are in a separate room from the home theater but it's definitely audible if you're near the rack.

Purchased three years ago, I do not regret it. The sound is good, the device compact, rack mountable in 19 'and has a connector adapted to (almost) all possibilities. Only drawback, at a party, it is put repeatedly safe (both channels) while he was on for a short time and at half power.

Very good amp, many possible connections, compact and in rack 19 '.
