Signaling of Incoming Talkback: If incoming talkback is activated, the corresponding TALKBACK key illumi-
nates.
Red-Light Signaling: The red-light indicators ON AIR, CR and ST are contained in the monitoring/TB
module as well as on the central screen. For details, refer to chapter 5.6.
TB with User GUI Soft Buttons: Additional talkback destinations may be configured to the programmable but-
tons at the right-hand side of the central screen. This feature requires editing
an XML file and cannot be configured by a normal user.
5.5.3.1 Talkback Groups
Every location (TB from CR or from Studio) has up to four TB groups avail-
able. The operator can talk from one location to several different TB destina-
tions at a time by pressing a single TB group key.
TB Group Setup
TB groups are set up as described in the steps below:
• Press the STORE key on the desk, or touch the STORE button on the MON
- TB SP page.
• Select the TB group to be defined (escape by pressing STORE again). All
currently active talkbacks from this location are turned off. All destinations
of this TB group existing already will be selected. Pressing the TB GRP x
key (or button) again will clear the selected group.
• Collect the destinations by selecting them with their keys or buttons (or
GPI, if available). TB destinations to N–X can be selected either by press-
ing the TB key on the fader strip, or by touching the joker button configured
with the TALK function on the FDR - Bus page.
Note: Only destinations within the TB group’s own location may be selected. TB
destinations of the studio microphones no. 2...4 can be selected only when
using GPI.
• End by pressing STORE again.
The TB group settings are saved in the initial and assignment snapshots.
STORE and TB GRP x key functions may be assigned to any desk key, chan-
nel-related keys excepted.
TB Group Functions
TB group activation, together with the momentary/latching key function (refer
to chapter 1.1), is very flexible and intuitive:
• You can, for instance, activate or deactivate a TB group permanently by hitting
its key (“latching”), or just for a short while by holding its key for as long as
required (“momentary”).
• A TB group’s member that already has been active when the group is activated
remains active but gets deactivated when the group is deactivated.
• While a TB group is active, you can deactivate one or several of its members
permanently by hitting the TB key of the desired group member – or just for
a short while by holding its key for as long as required.
• When a talkback destination is member of more than one TB group, and both
groups have been activated at the same time, this destination is deactivated as
soon as one of the corresponding TB groups is deactivated.
• You can even de-activate a group with its TB group key while holding down
the TB key of one of this group’s members. Then this member remains active
until its TB key is released.
