MaxRMS Level (MaxRMSLvl)
This sets the maximum RMS signal level at the Module outputs. It is adjustable from -30 dBu to +30 dBu in 0.1 dB
increments, subject to user-dened level limits. The Group total is displayed (in brackets) for each channel.
MaxRMS Corner (MaxRMSCor)
A soft-knee or hard-knee corner may be applied to the RMS Limiter. A soft-knee corner gently increases limiting as
the signal approaches the threshold; a hard-knee corner applies full limiting to any signal exceeding the threshold
by any amount, but none to signals below the threshold.
The Corner parameter is adjustable in 0.1 dB increments, subject to dened level limits. This gure represents the
level below the limiter threshold at which compression commences; the larger this negative value, the softer the
knee. A setting of 0 dB implies a hard-knee characteristic.
Note: LimiterMax provides peak and RMS limiting features, referred to as MaxPeak and MaxRMS
respectively. Full details regarding LimiterMax can be found in the Lake Controller Operation Manual.
MaxRMS Attack
The attack time may be set for the RMS Limiter. Limiter release values are set separately for each of the four
outputs in 0.10 ms increments.
MaxRMS Release
The release time may be set for the RMS Limiter. Limiter release values are set separately for each of the four
outputs in 0.10 ms increments.
7.11.2.7. Mutes
MENU > MODULE > MUTES
In Meter Mode, Module inputs and PLM+ power output channels can be muted using the MUTE ENABLE
function. The MUTE menu also provides mute status and control of the Module input mutes, but instead of the
PLM+ power output channel mutes, it provides the ability to mute the Lake Module outputs.
Press the associated dynamic function button/s to select the Module input/s and/or Module output/s to be
adjusted. Use the rotary encoder to toggle between the MUTED and UNMUTED states.

Figure 7.17: I/O Conguration Sub Menu
This menu provides conguration options for input routing, along with settings for AES Termination and Iso-Float as
described in the following sections.
7.11.3.1. Input Router Configuration
MENU > I/O CONFIG > ROUTER
Figure 7.18: Input Router 1
The signal ow diagrams in section 6 highlight that there are four Input Routers available on PLM+ Series devices.
The input that is selected within the router can be used by the Input Mixer for any of the modules.
Each router has four priority levels allowing any input to be placed in a sequence providing automatic input signal
fail over. Dante and AES3 inputs have priority over analog inputs.
Note: Only one analog input is allowed in each router, and the analog input must be at the lowest
priority level in relation to any other inputs.
Two modes of input selection are available, Auto Select and Forced Selection. The selected setting is also visible
from the I/O STATUS screen on the front panel, and via the Lake Controller.
In Auto Select mode, Priority 1 is checked for a valid input signal; if no signal is found, Priority 2 is checked, and so
on until a valid signal is located; this process occurs if the currently selected input fails. In Forced Selection mode,
one of the four priorities is xed regardless of whether a valid signal is present.
