Audio Signal is Present
This LED will illuminate when the amplifier detects
an audio signal.
Amplifier Channel is Clipping
If the amplifier is clipping, this LED will illuminate.
Limiter is Active
When the amplifier reaches the point of clipping,
the limiter LED will illuminate. This indicates the
limiter circuit is reducing the audio input signal, in an
attempt to stop the signal from clipping.
Amplifier Channel is Thermally Limiting
If the amplifier reaches a critical temperature level,
the limiter circuit will activate in an attempt to keep
the amplifier temperature within its limits.
Amplifier Channel is Muted
If Auto-Standby is enabled via the switch on the rear
panel, the amplifier will enter a mute state after no
audio signal has been present for ~10mins.
Amplifier Channel is in Standby Mode
If Auto-Standby is enabled via the switch on the rear
panel, the amplifier will enter a standby state after
no audio signal has been present for ~30mins. This
mode enables that respective amplifier channel to
draw <0.5W of mains consumption during a standby
state.
