Sonodyne AM21P - Manual (Page 4)

1 Signal Indicator
The signal indicators (blue) illuminates when audio is present on the relevant
amplifier channel.
2 Fault Indicator
The fault indicators (red) illuminate when a fault is detected on the relevant
amplifier channel.
A fault may be detected due to short circuit conditions or internal failure.
3 Clip Indicator
The clip indicators (red) illuminate when an amplifier channel is approaching full
power or clipping.
If this occurs often, the input source or amplifier gain should be reduced
accordingly. Alternately the compressor block for the effected channel could be
set to avoid the clipping condition.
4 Control Indicator
The control indicator (blue) blinks whenever a third party control system
accesses the amplifier or adjusts an operating parameter.
The control indicator also blink briefly when the amplifier is in the low power
standby mode.
