Talkback and Oscillator
Talkback is a function that sends the signal of the selected INPUT jack to the desired bus. This
is used mainly to convey instructions from the operator or sound engineer to the performers
and staff.
QL series consoles also feature an oscillator that can output a sine wave or pink noise to the
desired bus, so that you will be able to check external equipment or to test the acoustical
response of the room or hall.
The diagram below shows the signal flow of the talkback and oscillator signals.
Using Talkback
The Talkback function sends the signal (that is input at the input jacks) to the desired bus.
NOTE
• The PAD will be switched on or off internally when the HA gain is adjusted b17 dB and
+18 dB.
• Keep in mind that noise may be generated when using phantom power if there is a difference
between the Hot and Cold output impedance of an external device connected to the INPUT jack.
• You can also assign talkback on/off or an ASSIGN change to a USER DEFINED key. In this case,
you can select either a Latch operation or an Unlatch operation (the function will be enabled only
while you continue holding down the key) (
page 194 ).
• When talkback is on, you can use the talkback dimmer to lower the monitor levels other than the
talkback signal ( page 99 ).
