Play DVA Button

The button function is 'play DVA to selected outputs'. When the button is pressed a route is made connecting
a DVA audio source from the Slave Unit or the Audio Control Unit to outputs which have been pre-selected
using buttons configured for zone selection.
It is possible to configure how the route will be triggered:
•
Not Latched mode
The first press of a Play DVA button initiates a route, and a second press terminates it.
•
Latched mode
This mode needs a reset button. Pressing a Play DVA button initiates a route; and pressing the
associated reset button terminates it.
•
Play Once mode
Pressing a Play DVA button plays the DVA associated with the route once only. When the DVA has
completed its full message cycle, the route is terminated.
The DVA assigned to a button may be configured to cease playing when the route is terminated or reset
(DVA-Part), or play until its end (DVA-Full).
It is also possible to configure whether or not the route associated with a Play DVA button should cause a
busy indication on the LEDs associated with microphone zone select buttons.

1. Select the microphone button to be programmed.
