Application 3 - Using The MPL 1502 As A Keyboard Submixer
Here, various keyboards and MIDI tone generators are connected to the mono and stereo line inputs of the MPL 1502.
Signal processors are connected to Aux sends and returns and to channel inserts as required. The Main output can then
be routed to a stereo input channel of a live performance or recording mixing console, with the performer having
complete control over the blend of signals being provided to the sound engineer.
