TB / MIC Panel (TBM-D12)
Controls and Functions
The D-12 digital audio control surface is equipped with one
TALKBACK/MIC Panel. This panel houses the TALKBACK MIC,
the TALKBACK preselects, and the PROGRAMMABLE buttons
sections.
Programmable Buttons
These (16) momentary switches and indicating
LEDs are designed for user accessible external
functions (GPIs). Users modify behavior of the
switches/leds in the OPTIONS.TXT file for the
surface (see sample in Appendix 2). The XPoint
GUI is used to map Salvo or Preset takes or Tempo-
rary Connections to these switches.
These switches may also be mapped to control
physical Logic card output ports, and the LEDs on
the Spare buttons may also be lit by a remote device
connected to a Logic card input port. See the Bridge
Router manual for details.
Talkback Mic
The operator’s talkback mic plugs into the panel
mounted XLR connector located on the upper-right
corner of the panel. This a jack only with no pream-
plifier built into the D-12 control surface. This
signal is then available for the various TALKBACK
functions of the control surface. The XLR-M con-
nector is wired to the “TB MIC” DB-9 connector
located on the control surface’s rear panel. This
DB-9 connector must be wired out to a destination,
such as a Bridge Router mic input (phantom power
is supported), to be usable by the system.
Pin 1 XLR SH – Pin 4 “TB MIC” DB-9 SH
Pin 2 XLR HI – Pin 5 “TB MIC” DB-9 HI
Pin 3 XLR LO – Pin 9 “TB MIC” DB-9 LO
XPoint software is used to route the user defined
TB MIC source signal to the D-12’s auto generated
TBACK input signal. Note that any source on the router can be the TB
source.
