Looks pretty shady to me.

  • There are no real specifications, just a list of features.
  • I don't think a 600W continuous amp can be packed into that case which clearly relies on convection cooling.
  • There are no reviews of this anywhere, and indeed goofle only brings up one direct hit.

I/M/O, stay away from that.

600W continuous amp sounds like the old sears 100W Sound Power Rating (garbage rating) No THD rating (total harmonic distortion)

Why don't you by the AS-6000DPE?

What is your intended application? What Speakers do you have now? Do you need more than 2 stereo speaker outputs i.e. A/B/A+B ?
What type of Microphone Inputs? XLR/Phone Jack?
What is your budget... Amplifiers range from a few hundred to many thousands of dollars

For that application a built-for-the-purpose constant-voltage commercial PA amp is needed.  Running audio at output level any distance requires a 70.7 volt (in the EU 100 volt) system and that is only found in PA amps.

Alternatively, distributed low-level audio with amplfiers at the speakers can be used; but my own experience says "Stay well away from that."
