Application 2 - Using The MPL 1204 As A Main Live Mixer
Here, the MPL 1204’s Main output is connected to the input of a power amplifier, and, from there, to PA speakers.
Microphones and line level signals are connected to various channel inputs, and a two-track tape deck is connected to
the Tape/CD inputs. A submix from Aux send 1 (which is pre-fade) 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. Signal is
being sent to an external signal processor via Aux send 2, with a stereo return from that processor is connected to
Aux return 1/2. Another signal processor is connected to channel insert 1 so as to affect the signal coming from the mic
connected to channel 1, and a third signal processor is connected to Bus insert 4 so that a submix of all channels routed
to bus 4 are processed simultaneously.
