Under some conditions, such as a shorted speaker wire, DC
voltage on an input connection or thermal overload, the
amplifier will place itself in a protect mode to prevent
damage to the amplifier. When this happens, the LED

amber.
When this occurs, IMMEDIATELY turn off the unit using the
power switch and correct the problem. Then turn the unit
back on. If the unit continues to go into protect mode,
