Talkback / Oscillator
This chapter explains how to use the talkback and oscillator functions.
Talkback is a function that sends the signal of the selected INPUT jack to the desired bus. This is
used mainly to convey directions from the operator to the performers and staff. The LS9 also con-
tains an oscillator that allows a sine wave or pink noise to the desired bus, and this can be used
to check external equipment or to test the response of the room.
The diagram below shows the signal flow of the talkback and oscillator.
Here’s how a signal received at an INPUT jack 1–16 {1–32} can be output to the desired bus.
1In the DISPLAY ACCESS section, press the
[MONITOR] button repeatedly to access the
TALKBACK screen.
In the TALKBACK screen you can check the status of
the talkback and turn it on/off.
