d. Test the controller's configuration with the following:
• Check that the MLC is controlling the PVS 204SA
switcher and projector, and does output the
correct image when switching inputs.
• Check the projector's power control (turn it off
and on at the MLC controller).
• Adjust the configuration as necessary.
e. Adjust the audio input sensitivity as follows:
• Ensure there is an audio source at each transmitter.
• Set the MLC controller's volume to maximum.
• On the PVS 204SA switcher, press and hold the
selected input buttons for 3 seconds. The input's
LED will blink.
• While holding the input button in, rotate the level
encoder until the clip LED blinks, then turn the
encoder back down until the blinking stops.
• Repeat Step e for all inputs.
f. If necessary adjust the amplifier level by rotating
the same encoder used in Step e.
g. If necessary set the Aux/Mix level by rotating the
Aux/Mix encoder.
