  • Wonderful simple matrix amplifier combo.
This unit does exactly what it claims. All functions seem to work well without any quirkiness to it. This turned out to be the perfect solution to a 4 way split dividable classroom arrangement.

  • great feature packed PA system for a restaurant. Has bluetooth, plays MP3s.
Bought this for a small restaurant and used the 70-volt output for ceiling speakers. Had everything I needed for multiple microphones, paging override, zoning for different rooms. Solidly built heavy unit. I liked it so much that I bought another model for another use. I am a pro A-V guy used to installing complex systems, and this one box was great for the small restaurant. ... show more

  • Four zones at 110watts each.
So far so good. There are four zones in the back with 110 watts each. Took a while to troubleshoot why there was no sound when using Bluetooth. There’s a button in the back that needs to be pressed. Duh! Downside- when you plug in a USB, it starts up the music file right away. I would like the option to press play when I’m ready to. Then if you take out the usb and reinsert it, it starts up in the same place it left off mid-music. Other than that, it works for now. ... show more

  • NOT GOOD
The unit was no good added (6) of the same brand pendant speakers the sound was horrible. You could not turn the volume up more than a quarter way. I checked all configurations 75 V 120 V. I even changed all the settings on the speakers and still no good. Highly recommend you stay away from this particular unit. The pendant speakers from this company is OK. And will get the job done On another system but this receiver is no good ... show more

  • VERSATILE AMP
Very versatile power amp. for commercial use. Easy to install. Easy to program. Hard to find a 4 zone amp with 110 w per zone. Unless you are willing to dish out $2,000. There is even a "Rockville" with 6 zone distribution. Great, Great, Great. Also, "Rockville" customer support very efficient.
