The 559 Stereo Power Amplifier includes a thermal shutdown,
which mutes the output if the amplifier becomes too hot. The
Standby LED will also become red.

Standby LED will turn green.
The amplifier can then be taken out of standby using the front
panel button or the TRIGGER INPUT.

breaker to protect the loudspeakers. This is also triggered if the
mains supply is interrupted.
