1 Standby/On LED indicator – A three-color LED illuminates amber when amplifier is in standby power mode
and illuminates green when the amplifier is on. When the amplifier enters Protection Mode, the LED flashes red and

2 Signal present/limit/clip indicators – A three-color LED illuminates to provide channel status information as
follows:
Green – Signal is present at the input and the channel is operating normally.
Amber – Limiting is active on the channel. Limiting is engaged when:
• The channel reaches the voltage limit as determined by the automatic Voltage Peak Limiter (VPL) setting
• Maximum current output is reached
• Mains voltage cannot maintain rail voltage
Red – Channel is clipping either at the input or in DSP
3 Signal attenuators – A signal attenuator is provided for input channels 1 and 2. Attenuators are adjustable over
a range of – infinity to 0 dB.
4 Airflow input – Make certain this input is not blocked or covered.
