The 100dB signal to noise ratio on the amplifier insures the clearest audio signal. Both the 1/4" and XLR input jacks offer total versatility in setting up. System failure is the worst nightmare for all the commercial operators, this is why the VP-600 PRO amplifier has a built-in five way protection system to insure proper operation at all times. With features like the 19" rack mountability and the variable speed forced air fan, the VP-600 PRO can be protected in road cases or amp racks without overheating. The VP-600 PRO amplifier outputs 600 watts of power RMS and takes only two rack spaces!
