Signal / Peak Indicators
These 2-color LEDs indicate the signal level for each channel. When an LED is green, that channel
has signal (above -30dB). When an LED is red, that channel signal is clipping (max. power).
CAUTION: Signal levels should be adjusted to avoid clipping. Clipping can cause severe distortion,
over-temperature conditions, and even loudspeaker damage.
NOTE: Signal / Peak indicators will turn off during Temp / Fault conditions (see Temp / Fault
Indicators below).
Temp / Fault Indicators
These red LEDs indicate over-temperature and output fault conditions for each channel. When an
LED remains lit, that channel has an over-temperature condition. When an LED is flashing, that
channel has an output fault condition. Either condition will temporarily de-activate the channel,
causing the Signal / Peak LED to turn off as well. The channel will attempt to self-reset once the
over-temperature or output fault condition is resolved.
On Indicator
This green LED remains lit when AC power is applied to the unit.
