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

– Make certain this input is not blocked or covered.

Note: In LUCIA constant voltage mono models (60/1-70, 120/1-70 and 240/1-70), the attenuators act as an input

select and mixer by adjusting each input level that goes to the single output channel.
