Applications
Here are four suggested applications for the MPL 1502; bear in mind that your particular circumstance may dictate changes in these suggested signal connections and routings.
Application 1 - Using The MPL 1502 As A Main Live Mixer
The main connections here involve routing the MPL 1502’s Main output to the input of a power amplifier, and, from there, to PA speakers. Microphones and monophonic line level signals requiring insert processing are connected to mono channel inputs, while stereo line level signals are connected to stereo channel inputs. A tape deck is connected to the rear panel tape in/outs (making it easy to record the gig) and, for playback, the signal is returned to stereo channel 14/15 by setting the “Tape In / Channel 14/15” to the “on” position (pressing it in). Signal processors are connected to Aux send 2 (and either or both Aux returns) and to channel inserts as required. A submix from Aux send 1 is connected to the input of a second power amplifier driving onstage monitor speakers so that performers can receive a monitor mix independent of the house mix.
