balanced output allows a direct connection to
a P.A. system.

Turns the amplifier on and off.
In the on position, the ring surrounding the
button will light red during power up then
changes to blue, indicating the amp is ready
for normal operation. Should the amp
experience a fault (over heat or over current)
the amp will mute and the ring will light red
until the condition is corrected. This LED
turns off when the power is switched off. This
turns the amp off but it does not completely
disconnect the power from the AC mains.
