Application 3 - Using The PL 2404 As A Keyboard Submixer
Here, various keyboards and MIDI tone generators are connected to the channel line inputs of the PL 2404, with stereo
signals routed to “matched” consecutive odd- and even-numbered inputs. 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.
