Talkback
TALKBACK (TB) BUTTON - There may be times when
the control surface operator wishes to talk to the Studio floor
through the studio speakers. When the TB button in the studio
monitor section is pressed, a predefined signal, usually the
operator’s intercom mic, will “interrupt” the speaker feed that
is normally heard in the studio.
The TB source signal can be any source on the Wheatstone
router. You must route the desired source to the D1TBk signal
using XPoint.
If there is a live mic in the studio which has activated the mute feature, talkback
will also be muted in the speakers. Below the top-center of the MON-D8 panel is the
TB master level control that sets the talkback output and the level of the talkback
interrupt signal.
CUE/PFL Section
The CUE/PFL master level control is located in the center section of the MON-
D8 panel. The CUE/PFL signal is pre-fader, and is normally used to check signal
integrity. When a channel is CUE’d, its pre-fader signal will appear in the surface’s
D1PFL mix, and the switched meter array on the MAIN screen will show the level
of the pre-fader signal.
The CUE/PFL level control determines the overall loudness of the cue signal.
Engineering Notes
There are two ways to listen to the PFL mix. Most users will route the D1PFL
mix to a stereo or mono analog output that is connected to dedicated PFL speakers.
Alternatively, you can program the CR or Studio outputs to interrupt whenever a
PFL switch is engaged. Programming is done by editing the CUE interrupt section
of a text file called D8_opts.txt. The file is located on the D8’s internal flash hard
disk. Access the file by FTP’ing to the surface, as described in Appendix 1.
Similar to the control room speakers, the cue speaker also has the potential for
feedback and should be muted (using the configuration software—VDIP menu)
whenever the control room speakers are muted.
