7.8.4.3 Module Input Mute
The Module input mute provides the ability to mute/unmute the audio signal at the module level. Therefore,
the PLM input (described in 7.8.4.2) remains unmuted and can be used by another module, or directly
routed to an output. To mute or unmute a Module input:
1. Press METER until Home View is displayed
2. Press MUTE ENABLE
3. Use the associated dynamic function buttons to mute / unmute the Module inputs
Once the Module input is muted, the LED turns red and MOD. IN MUTE is displayed on the LCD. When
unmuted, the LED turns green (unless any other output warning conditions are active)..
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.
Module Input Mutes may also be controlled in Menu Mode. See section 7.11.2.6 for further details.
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 unavailable via MUTE ENABLE in Meter Mode, as the PLM power output
mutes are assigned in this mode (see section 7.8.4.5). However, Module output mute status and control is
available in Menu Mode and may also be viewed and controlled from the Lake Controller software.
Please refer to section 7.11.2.6 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 Output 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).
