Ask the owner was informed that recently opened a small dance floor, this amplifier speaker to play music, as it is an outdoor open space, so was turned hard, indoors before a smaller volume is sufficient. Now all clear: 125V power amplifier Board power supply of the machine, in a mono 8 ω loads about 30W output power, two-channel total 30W +30W, 60W output power, in the indoor use of output power is sufficient, but in outdoor situations the output power is clearly inadequate, only trying to turn up the volume, 15-inch bass accelerated aging.nsfservice manual download site
