Lake LM Series Operation Manual Rev 1.3.5
The audio signal may be delayed (typically for reasons of driver or delay subsystem alignment) at either
the Module inputs or on individual outputs. Delay added at the inputs affects all outputs equally, and will
be generally be introduced to time-align arrays of loudspeakers at different locations. Delaying individual
outputs may be desirable to time-align drivers in the same cabinet or array.
6.10.2.4 Phase (Polarity)
MENU > MODULE > PHASE
Module Phase adjustment follows the same logic as Module Gain. Please refer to the section 6.10.2.2 for
further information. Phase may be changed on one input or output at a time.
Audio phase reversal is available at the inputs to Module A and Module B, and also individually on the
six output channels. The LCD displays ‘Positive’ for normal operation, and ‘Negative’ when the phase is
inverted.
6.10.2.5 Limiters
MENU > MODULE > LIMITERS
LimiterMax parameters can be adjusted via this submenu. By default, simultaneous adjustment of most
limiter parameters across all output channels is selected, although channels may be adjusted individually if
required. Attack and Release times must be adjusted individually per channel.
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.
