Talkback / Oscillator
This chapter explains how to use talkback and oscillator.
Talkback is a function that sends the signal of a mic connected to the TALKBACK jack to the
desired bus. This is used mainly to convey instructions from the mixing engineer to the perform-
ers or staff. If necessary, a mic connected to INPUT jacks 1–32 {1–48} can also be used for talk-
back.
The M7CL also contains an oscillator that can output a sine wave or pink noise to the desired
bus, and this can be used to check external equipment or to test the acoustical response of the
room.
The diagram below shows the signal flow of the talkback/oscillator signals.
Here’s how the signal sent to the TALKBACK jack or an INPUT jack 1–32 {1–48} can be sent to
the desired bus.
