7.11.2.2. Gain
MENU > MODULE > GAIN
Figure 7.16: Module Gain Edit Screen
Press the illuminated button next to the module 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
dened level limits.
7.11.2.3 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 dened
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.
7.11.2.4. 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 Modules A - D, and also individually on the four output channels.
The LCD displays ‘Positive’ for normal operation and ‘Negative’ when the phase is inverted.
