PLM Series Operation Manual rev 1.2.3
The default ISVPL Profiles differ depending on the PLM Series model:
▸ PLM 10000Q / 20000Q: UNIVERSAL
▸ PLM 14000: SUB/LF
MaxPeak Level (MaxPeakLvl)
This sets the maximum peak signal level at the Module outputs. It is adjustable from -30 dBu to +30 dBu
in 0.1 dB increments, subject to user-defined level limits. The Group total is displayed (in brackets) for each
channel.
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-defined 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 exceed-
ing the threshold by any amount, but none to signals below the threshold.
The Corner parameter is adjustable in 0.1 dB increments, subject to defined level limits. This figure repre-
sents 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.
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.
7.11.2.6 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.
