9.6.1.4 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.

3. For microphones provided with security key, program the security key as required by selecting the
‘Protected’ mode, and then the key-switch. By default the button is ‘Not Protected’.
When protected, the key must be turned on for the button function to be allowed. One key-switch may be
configured to protect more than one button.
The security key is intended to safeguard emergency DVA triggers from inadvertent operation.
