Applications
Here are four suggested applications for the MPL 1640; bear in mind that your particular circumstance may dictate
changes in these suggested signal connections and routings.
Application 1 - Using the MPL 1640 as a main live mixer
The main connections here involve routing the MPL 1640’s Main Mix output to the input of a power amplifier, and, from
there, to PA speakers. Microphones and line level signals are connected to various channel inputs. Signal processors
are connected to Aux sends and returns and to channel inserts as required. The Main Mix inserts are connected to a
room equalizer. Finally, 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.
