NOTE: Fault condition LED indications take priority over mute status indications. If a fault condition
occurs, the LED will indicate the fault by flashing and will note the mute status. When a Frame fault is
active the audio on all channels is muted.
Module Input Mutes may also be controlled in Menu Mode.
Please refer to the Lake Controller User Manual for details of mute selection via the software.
7.8.4.4. Module Output Mute
Module Output Mute is part of the Lake Processing system, at the crossover outputs. It is post Module output EQ
and level adjustment, pre PLM+’s protection circuitry.
Muting of the Module outputs is available via MUTE ENABLE in Module Meters view, as the PLM+ power output
mutes are assigned in this mode (see section 7.8.4.5). However, Module output mute status and control are also
available in Menu Mode and may also be viewed and controlled from the Lake Controller software.
Please refer to section 7.11.2.7 for details of selecting Module Output Mute in Menu Mode.
Refer to the Lake Controller User Manual for details of mute selection via the software.
7.8.4.5. Power Channel Mute
The four dynamic function buttons to the right of the LCD control the Power Output Mutes of output channels 1-4.
These mutes are located within the PLM+’s power output stage.
When a PLM+ power output is muted, the LED turns red and the text AMP CH. MUTE is displayed on the LCD.
When unmuted, the LED turns green (unless any other output warning conditions are active).
NOTE: Fault condition LED indications take priority over mute status indications. If a fault condition
occurs, the LED will indicate the fault and not the mute status.
