8-channel audio interface
1. Be sure all used channels have properly made-up cables and connectors.
2. Play the audio source and check to see signal presence is indicated for all active channels.
3. While the audio source is playing, select each channel to the VU meter and verify the loudest sounds are
peaking to zero VU with maybe a few peaks hitting +3. If the reading is too high, you can trim down the gain
of the offending channel. If the level is too low, make sure the trimmer is set to the full-clockwise position for
maximum gain. If there is still not enough gain available to bring the VU indications up to 0VU, then your
source’s output level needs to be brought up by increasing its output level controls.
