Talkback/Oscillator

Talkback is a function that sends the input of a mic connected to the TALKBACK MIC IN on the rear panel jack to
an AUX bus, MATRIX bus or the MAIN L/R bus. This is useful when the mixer operator needs to convey
instructions to performers on stage or to staff.
Oscillator is a function that generates pink noise, white noise, or a sine wave, and sends it to an AUX bus or
MAIN L/R. This is useful when you need to measure the acoustical response of a hall, or when checking the
connections of external devices.
You can also output the talkback or the oscillator directly via the output patchbay without routing the signal
through a bus.
Talkback and oscillator operations are performed in the Talkback/
Oscillator section.
