Application 2 - Using The MPL 1502 As An Onstage Monitor Mixer
Here, the MPL 1502 is receiving monophonic signal into its line inputs from the direct channel outputs of a main live
mixer. Its Main output is connected to an outboard signal processor (typically an equalizer) prior to being routed to an
amplifier and onstage monitors. This allows the overall mix to be adjusted in order to eliminate feedback and ringing
problems.
