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)
• Talk to a to an external location, such as an external intercom system or a
different OnAir console ( TALK key)
• Controlling the digital input gain of each TB input (±24 dB; hold the
PFL
key and adjust with the rotary encoder)
• Setup of the analog gain of a mic input (Channel – Input page of the user
GUI)
• Master volume control using the rotary encoder (TB return level)
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.
