Chapter 2 - The Master Screen

Whenever a macro button is pressed, it performs what we call an On action. This is the first press of the macro button. The next
press of the same macro performs an Off action. These On and Off actions can be the inverse of each other, so instead of
having alternative presses of the macro button just toggle the state of a controller, you can program the macro button so that first
press is a definite mute on command and the 2nd press of the macro button is a definite mute off command. This has the advan-
tage of being able to provide an indicator on the Macro button of the state of the controller. On and Off states can have different
colours and different text.
Macros can be tested by touching the fire macro button, located in the top left-hand corner of the display. Once the macro has
been fully configured, close the Macro Editor display.
2.13.14 Talkback ............................................................................
The Talkback display is opened by selecting Talkback from the Setup menu. This is where the talkback busses are configured.
In the right-hand side of the Talkback display, there is a mic input gain pot which is always assigned to the gain encoder in the
worksurface talkback area. The pot’s gain value is indicated in dB in the box above the pot. The talkback signal level is shown in
the meter to its right. Touching the white box below the gain pot opens up the Talkback Input display which consists of an input
route button. The current route is displayed below the button. Pressing the button opens up the TB Input Route display, which
functions in the same way as all other input routing panels.
To the left of the input section of the display, there are talk buttons with text boxes beneath them. Touching each button enables
and disables the corresponding talkback button on the worksurface. The button rings red to indicate that the buss is active.
Touching the text box beneath the button opens the TB Outputs display for that talk bus. This consists of a naming area and an
outputs button. The first output currently selected is displayed below the button.
Pressing the button opens up the TB Output Routes display which functions in the normal way. The first selected route appears
in the text box below the talk button.
The three blue coloured text boxes above the buttons provide access to a panel allowing the selection of a number of aux
busses.
Once selected, the Talkback button will automatically activate the talk To Aux functions on those busses. This enables you to talk
to multiple Auxes of your choice at the press of a single button.
Talk To Auxes
In order to talk to individual or multiple of Aux outputs there is an assignable row of controls on Aux channels, controllable
independently or from the Talkback panel which has a Talk to Aux Setup list for each Talk button.
This is implemented as a Talkback Input channel which uses a single engine processing channel to provide the aux sends. This
channel appears, in a default session, on its own in the last bank on the left of the console.
