9.10.1.1 PLM Input Mute

Muting of the PLM's inputs is not available via the MUTE ENABLE button in METER mode. It can however
be actioned from the INPUT meter view - via the MUTE ENABLE button in the INPUT view and from the
Lake Controller software. When in the INPUT Meter View, the two vertically centered buttons to the left of
the display represent the two physical inputs. When Mute Enable is active these buttons control the Input
mute.
PLM Input Mute is within the Lake Processing system, post input type selection, and pre input mixing and
routing.
Refer to the Dolby Lake Controller User Manual for details of mute selection via the software.

9.10.1.2 Module Input Mute

When in HOME, MODULE or TEMPERATURE view, the center pair of soft function buttons to the left of
the screen (buttons 2 and 3 - see figure 9.10.1a) control the module input mutes. Note that position of the
modules and associated mute buttons will be changed if channel order is reversed using the "Top-down"
and "Bottom-up" menu selection. (See section 9.13.5.6.3.) In the INPUT METER view, the center two
buttons to the right of the screen control the module input mutes.
Module Input Mute is within the Lake Processing system and not at the physical inputs to the PLM. This
means it is possible to mute the input to one Module, while mixing input sources together and feeding the
sum to the second Module. This is not possible with the PLM Input Mute is activated.
Once the Module input is muted, the soft button's integral LED turns red and the text 'MOD. IN MUTE' is
displayed in inverse video. When unmuted, the integral LED turns green and the display shows the text OK.
Display of fault conditions always takes priority over
mute status displays on the soft button LEDs. If an
input fault condition arises, the LEDs will indicate
this and not the mute status. The mute status can
still be viewed via MENU mode or the Lake Controller
software.
Module Input Mutes may also be controlled from the menu system. See section 9.12.2.6 for details.
Refer to the Dolby Lake Controller User Manual for details of mute selection via the software.

9.10.1.3 Module Output Mute

Muting of the Lake processing system's Module outputs is not available via the MUTE ENABLE button
in METER mode, but instead through the PLM's MENU system. It may also be actioned from the Lake
Controller software.
Module Output Mute is within the Lake Processing system, at the crossover outputs. It is post Module
output EQ and level adjustment, but pre any of the PLM's protection circuitry.
See section 9.12.2.6 for details of selecting the Module Output Mute via the menu system.
Refer to the Dolby Lake Controller User Manual for details of mute selection via the software.
