Application 2 - Using the MPL 1640 as an onstage monitor mixer
Here, the MPL 1640 is receiving signal into its line inputs from the direct channel outputs of a main live mixer. Its Main
Mix output is connected to an amplifier and onstage monitors, and the Main Mix inserts are connected to a graphic
equalizer. This allows the overall mix to be adjusted in order to eliminate feedback and ringing problems.
