Control 24 Reference Guide50
Talkback
Talkback is a dedicated signal path that sends a
microphone feed from the control room to any
remote locations through the AUX output buss.
This Talkback signal is also routed to the Slate
output for logging, marker, and note-taking pur-
poses.
Listenback
Listenback routes an external microphone feed
back to the Control Room Monitor section, for
bi-directional conversation between the control
room and the recipients of the Talkback signal.
When Listenback is engaged, the control room
outputs are muted. Pressing the Listenback but-
ton again toggles the Listenback circuit off, and
the control room outputs are reactivated.
Using Talkback and
Listenback
A built-in Talkback microphone is mounted
into the Control 24 surface, and phantom-pow-
ered connectors for external Talkback and Lis-
tenback microphones are provided on the back
panel. The talkback and listenback channels are
both adjustable from dedicated controls.
Located at the bottom of the Communica-
tions/Headphone section is a shock-mounted
microphone labeled TALKBACK MIC, with an
adjustable MIC LEVEL control.
External Talkback Input
For higher-fidelity or remote Talkback, an exter-
nal, phantom-powered XLR Talkback input is
provided on Control 24’s back panel. This is
provided as an alternative to the built-in Talk-
back microphone mounted in the Control 24
surface. Both Talkback options are controlled by
the MIC LEVEL knob.
Remote Footswitch Control of Talkback
Either footswitch circuit can be configured for
remote Talkback control via infra-red or other
control as a hands-free alternative to the TALK-
BACK button.
See Appendix B, “Utility Functions” for instruc-
tions to set up talkback control by footswitch.
To select the internal or external Talkback
microphone:
1 Press the Utility button.
2 Select “Monitor.”
3 Select “Talkback.”
4 Select “Internal” or “External.” The LED is
lights solid to indicate that the selected Talkback
mode is enabled.
5 Select “Exit” or press the Utility button again
to return to normal operation.
Talkback Level
As with the built-in Talkback mic, the level of
the external Talkback microphone is also con-
trolled by the MIC LEVEL control in the COM-
MUNICATIONS/HEADPHONE section.
