This is a good little amp especially for the price. It can get pretty loud and drives 8 ohm, 4 ohm, or 2 ohm configurations. The only thing I wish it had was a mono input and output for doing live music. With this unit you have right and left input and corresponding outputs and if the right input is plugged in no sound comes out of the left which is a little annoying if you have limited outputs from your system or console. This would be resolved with a 4 or 8 channel mixer to have more inputs and outputs then a console has but for the price it is a good unit and sounds clean and has a relatively low noise floor. In other words you don't hear static coming through the speakers at any volume especially when the volume is lower.

The power ratings shown are peak to peak power values for both channels combined. For example, 500W @ 4 ohms is really only 250W peak to peak power for each channel. This equates to 88.4 watts RMS per channel. If you are expecting 500W RMS per channel into 4 ohms, you are going to be very disappointed. Amp appears to be well constructed. No problems so far. Only rated this as 3 stars because I thought the specs were deceptive.

I bought 1 used off of craigslist. 2000w is quite deceptive. I replaced a 150w rms per channel amp with ths 1. It isn't as loud as my 150w rms amp but it does sound clean right up to clip volume. Having the level meters(led lights) is quite handy so I can run at the highest level below clip I can. It doesn't have line out xlr's to run a 2nd amp or to daisy chain powered speakers. I gave it 4 stars only because of the deceptive amp rating and no xlr outs. Worth $100 all day long, but, you may want to look at the higher watt unit... SYS-4500 if you need real power!

This power amp is excellent value. It replaced my Dynaco power amp it has fine clean sound. My only complaint is the two fan are way too noisy. I will replace them.

Small Church (room of 100 people) - Replaces the bad amplifier with this unit. I was surprised that it had a crisp clear sound. I turned the channel levels all the way up and added gain at the mixerboard preamp without distortion. Likewise, the unit was not clipping or peaking on the LED display. With better preamplification than my Mackie mixer, the output would be full and powerful. Reproduces the sound beautifully.
