OnAir Digital Mixing Consoles
Configuration:
6-72 Configuration
• Incoming call signaling, e.g. a DTMF decoder indicated by Ready GPInput
(PFL button light is flashing)
• Control of the digital input gain of each TB input (±24 dB; hold the PFL
key and adjust with the rotary encoder)
• Master volume control using the rotary encoder (TB return level)
• Talk to external lines (TALK key)
• Setup of the analog gain of a mic input (Channel – Input page of the user
GUI).
The following configuration steps only relate to the 'advanced mode' con-
figuration of the XL Box. It is assumed that the following configuration steps
are already done properly:
• LogicalInputs for external 4-wire connections, including N–X Control/TB
Destination
• N–X buses as return line for external 4-wire connections
• Monitoring, and
• the XL box assignment is done in the main screen ROUT – XL Assign
page.
• TalkBack – TalkBack – Source:
Use a TB Input for each LogicalInput used as external 4-wire connection.
The LogicalInput shall be the source of the corresponding TB input, e.g.
TBfromExt1-TBfromExt48 for 48 4-wire connections.
Note: If you use a studio TB input, the studio should not be used, as the
studio LSP will dimmed when listening to the external line (on incoming
TB).
• Config – LogicalInputs – TBMicCutEnable:
Turn OFF TBMicCut Enable of each LogicalInput used as external 4-wire
connection, since it should not be cut while listening.
Otherwise, pressing the PFL button for listening causes the TB input to
which the LogicalInput is assigned to be activated, cutting the LogicalInput
if it is on-air.
• TalkBack – TalkBack – Incoming TB Indication:
Turn OFF incoming TB indication for each TB input used for listening on
the XL box.
Otherwise, the button light of the corresponding TBtoExt output would be
flashing while listening to an external 4-wire connection input.
• Desk Common – XLSection – Listen:
Specify the XL box listening bus as TBto output of the monitoring location
where the external 4-wire connection inputs should be listened to. Listen-
ing is also possible on TBToExt1-TBToExt4.
If more than one XL Box is used in a certain location, all of them will use
the same listening bus.
• GPIOFunctions – GPInputFunctions:
Use a GPInputFunction for each LogicalInput used as external 4-wire
connection to set the READY status, in order to indicate external calls
(flashing PFL key).
• GPIOFunctions – GPInputFunctions – Source:
The GPInput coming e.g. from the DTMF decoder cards.
• GPIOFunctions – GPInputFunctions – Function Type:
Ready.
• GPIOFunctions – GPInputFunctions – Argument 1:
The LogicalInput of the corresponding external 4-wire connection.
