LIVE has two Talkback paths, each with two inputs and two types of output, catering for a wide variety of modes of operation.
These Talkback paths allow you to run two independent Talkback systems.
For example, you might use Talkback 1 for a backstage cue speaker and Talkback 2 to speak to in-ear monitors.
Both Talkback paths have full channel controls with full signal processing.
Basic Talkback control is available in the Talkback area in the top corner of the Master Tile (shown left):
Turn the TB1 and TB2 encoders to change the fader level of the Talkback paths;
Press the encoders to Mute the Talkback.
The Talkback destinations can be summarised as follows:
The Talkback outputs (see above right) are used to feed remote speakers or headphones which may not have any other audio routed to it, such as a backstage cue speaker or another engineer's headphones.
Talkback outputs are switched on and off using the OUT 1 and OUT 2 buttons in the Master Tile.Note: Holding the Out button down it will switch off when you lift your finger; if you press it and don't hold it, it will stay on until you press it again.
You can send the Talkback paths to Aux paths (see right).
Talkback sends to Auxes are activated using the TB button in the Aux path's Fader/TB Quick Controls, as described further down this page.
Activating Talkback Inputs
The two inputs to each Talkback channel are switched in and out from the channel's detail dialogue:
A page similar to that shown below will appear (press the Input/Routing button if a different dialogue page is shown):
In addition, each input has a large Input IN button which switches the input in and out. (The buttons are blue when the input is in).
The XLR inputs under the console's arm rest are available for Talkback microphones; the left side is hard-wired to local input A15 (on the back of the console) and the right to local input A16. In the template showfiles, these inputs are routed to Talkback path 1 and 2 Input A respectively, and a signal generator is routed to Input B (but switched out of circuit by default).You should avoid plugging sources into an XLR input on the back of the console if a source is also plugged into the arm rest input which is hard-wired to it, as this will result in degraded audio performance.
Talkback outputs are routed using the Route Output button and their feed points can be selected using the Output Feed button (this does not affect the feed point for the Aux sends).
Sending to Aux Buses
By default, both Talkback paths are sent to all Aux buses at unity gain.
This can be changed with the standard Aux send controls, using the Quick Controls, detail dialogue, or Channel Control Tile.Note: If you add Aux paths to your configuration, they will need to be switched on and turned up manually in the Talkback paths.
Sends can then be adjusted within each Aux.
To access these controls, press the Fader/TB Assigner button in the relevant Aux path.
You can now press the TB button (to the left of the on-screen fader in the channel view section) to activate or deactivate the Talkback injection. The TB Dim control above the TB button defines how much the main Aux signal is attenuated when the TB button is activated.
The Dim and TB controls can also be accessed from the Quick Controls: Press the Aux's Quick Control encoder until the TB controls appear. The encoder will control the Dim level and the left Quick Control button labelled TB IN activates the Talkback to the Aux.
If you open the Fader/TB page of the Aux channel's detail dialogue, you will find the TB button duplicated there (labelled TB to Aux) and a TB Dim control.
