7.11.2.1 Gain
MENU > MODULE > GAIN
Figure 7-11: Module Gain Edit Screen
Press the illuminated button next to the input/s and/or output/s for adjustment, and use the rotary encoder
to change the value/s. Multiple gain values may be adjusted simultaneously in 0.1 dB increments, subject to
defined level limits.
7.11.2.2 Delay
MENU > MODULE > DELAY
Press the illuminated button next to the input/s and/or output/s for adjustment, and use the rotary encoder
to change the value/s. Multiple delay values may be adjusted simultaneously in 0.1 ms increments, subject
to defined level limits.
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.
7.11.2.3 Phase (Polarity)
MENU > MODULE > PHASE
Press the illuminated button next to the input/s and/or output/s to be adjusted, and use the rotary encoder
to change the value/s. 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.
