7. Front Panel Interface
7.8.4.1. Mute Functions
The PLM+ provides mute functions at several different points in its audio chain. Please refer to section 6.1 for
further information. The four types of mute are:
1. PLM+ Input Router Mute
2. Module Input Mute
3. Module Output Mute
4. Power Output Mute
With the exception of Module output mutes, all types may be controlled from the PLM+ front panel in Meter Mode
by activating MUTE ENABLE and selecting the associated input or output Meter View using the METER button.
Module Ouput Mute is available in Menu mode Module > Mute.
Note: Module input and output mutes can be controlled in Menu Mode via the MENU button. All mutes
can also be controlled from the Lake Controller.
7.8.4.2. PLM+ Input Router Mute
The PLM+ Input Router mute provides the ability to simultaneously mute/unmute all modules or outputs that are
sourced from the PLM+ input. To mute or unmute the PLM+ inputs:
1. Press METER until the Input Meter View is displayed
2. Press MUTE ENABLE
3. Use the associated dynamic function buttons to mute / unmute the PLM+ input router to the left.
Note: The PLM+ Input Router Mute is within the Lake Processing system, post input type selection,
and pre input mixing and routing.
Please refer to the Lake Controller User Manual for details of mute selection via the software.
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 Router (described in section 7.8.4.2) remains unmuted and can be used by another module. 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).
