6.5.28.2.1 TB/XL Box Configuration Examples/Tutorials
The following paragraphs can be used as configuration guides for two differ-
ent XL box ‘advanced mode’ applications:
  • Standardintercom
  • Listeningtoexternallinesthatarenotassignedtoafaderstrip.
Intercom With XL Box Instead of using the TB section of a Monitoring/Talback module, the XL Box
may be used for talkback control; it supports:
  • SoftwareindicationoftheTBsource(labeloftheLogicalInputisindicated
in the 8-character display)
  • IndicateincomingTB(flashingTALK key)

different OnAir console (TALK key)

Depending on the DSP configuration, a total of up to 49 TB inputs (TBfro-
mExtern, TBfromExt1..TBFromEx48) and 49 TB outputs are supported. In
each of the four monitoring locations up to four XL boxes allow talkback
from/to 48 external locations. This makes a total of 16 XL boxes connected
to a desk, i.e. four XL boxes per location using the same listening bus.
Incoming TB:
  • Config–LogicalInputs–LogicalInputX–Source(Left):
Take an unused LogicalInput for each incoming TB signal. It should not
be in any of the InputSelections as we do not want to assign it to a channel
strip. Configure it as Source (Left) of a TB input.
Note: If using a studio TB input, the studio should not be used, since the
studio LSP will DIM on incoming TB.
  • Config–LogicalInputs–LogicalInputX–InputFormat:
Set the input to Mono.
  • Config–LogicalInputs–LogicalInputX–Line/Mic:
Set the input to Line
  • TalkBack–TalkBack–Source:
For each incoming TB signal, set the source of a TB input to the appropri-
ate LogicalInput
  • DeskCommon–XLSection–Listen
Specify the Listen bus for the XL Box as TB to the desired monitoring
location, where you want to listen to incoming TB.
