Talkback
The mixer's built-in microphone allows you to talk to
the band through the phones outputs or stage monitors.
This can often be charming, pleasant, informative, and
enlightening.
TALKBACK MIC
The omni-directional dynamic microphone will pick
up your voice from anywhere in front of the mixer. Any
hint of exasperation and despair in your voice will be
faithfully picked up.
TALKBACK Switch
Press this switch in to talk. This is a momentary
switch, and as long as you hold it in, talkback is
activated.
When it is pressed in, the control room outputs are
attenuated (ducked) to allow your voice to come
through clearly.
TALKBACK LEVEL
Use the talkback level knob to control the level of the
signal from the internal microphone.
1. Start with this level turned down.
2. Select the destination: either headphones
and/or aux 1-2, and make sure the phones level
or aux send master levels are set up nicely.
3. Press the talkback switch as you talk.
4. Slowly turn the talkback level knob up until
they can hear you in phones or monitors.
5. Release the talkback switch when you are
fi nished talking.
Once you have set the level, you can leave it there for
the duration of the session or gig.
DESTINATION: PHONES, AUX 1-2
Push in the phones talkback destination switch to
communicate with the talent in the studio through the
headphones during a recording session.
The aux 1-2 talkback destination switch routes the
talkback signal to the aux send 1 and 2 outputs. Use this
to communicate with the musicians through their stage
monitors when you are setting up a live performance.
In a studio, the aux out could be fed to the input of a
headphone amplifi er feeding several sets of headphones.
It is fi ne to have both talkback destination switches
pushed in at the same time. If you don’t have either
switch pushed in, the talkback signal won’t go
anywhere.
