Talkback / Oscillator; About The Talkback And Oscillator Functions - Yamaha M7CL Owner's Manual

This chapter explains how to use talkback and oscillator.

About the talkback and oscillator functions

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, ST IN jacks, and OMNI IN jacks can
also be used for talkback.
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.
