Module Setup, cont.
Normal Mode
All sources are affected by the gain adjustment process. Background music source will need to be routed through the main mixer inputs, which will be affected by the gain adjustment process. Refer to page 12 for illustration.
Start with all POTS turned fully clockwise (AUX IN is not used in this mode).
1. Set MODE Switch to "SET" mode.
2.Set RELATIVE GAIN to the desired amount of sig- nal gain you would like the balanced/unbalanced input to ride over the ambient level.
3.Set MAX BOOST to limit the maximum amount of signal gain for the whole system.
4.Adjust AMBIENT THRESHOLD until the STATUS LED starts flashing amber, then adjust ACTIVITY THRESHOLD until amber stops flashing.
5a. Using the chart and diagram on page 13, set the AMBIENT THRESHOLD to the dBspl level where automatic increases to the system volume would be desired, then set the MODE Switch to ‘Run’.

5b. If the live ambient noise level (while making these adjustments) is at the desired trip point, set the MODE Switch to the ‘Run’ position, and then adjust the AMBIENT THRESHOLD control to a point where the STATUS LED flashes green.
6.Adjust RAMP SPEED to desired settings.
7.Test the system’s response to noise and, if neces- sary, set the ACTIVITY THRESHOLD control high- er if the maximum signal level is not achieved. Tweaking adjustments to MAX BOOST, RELATIVE GAIN, and RAMP SPEED controls may also be nec- essary.
