Audio (Event Type)

The Audio event is intended for PA control or mobile radio keying, that is, as an extension to the audio function of the 'owner' station. Normally the action for this event is the operation of a RCO. The Audio event is divided into a number of sub-events, which are closely related to each other, and which can be combined to operate the same RCO. UDP Groups cannot be used with Audio events. Audio events are not associated with a 'When Related to' number. In AlphaPro the sub-events can be selected after clicking the 'Details'-button.
