Features:
Primary mic mode: When audio sensed on MIC1 channel and/or PAGE contact closure is sensed then music is faded to pre-set level and MICS2-4 muted for the duration of the announcement. MIC1 zone LEDs flash slowly when in priority mic mode.
Secondary mic mode: When audio is sensed on MIC2, 3 or 4 then music is faded to pre-set level for the duration of the announcement. MICS 2-4 zone LEDs flash slowly when in secondary mic mode.
Emergency mic mode: When alarm contact is activated all zone feeds are muted and Mic1 is fed direct to all zones. All LEDs except mic1 LED are switched off for the duration. Mic1 LED will flash quickly.
Juke box mode: When music sensed on ST3, fade down current music feed and fade up ST3. When ST3 silent for pre-set period, fade down ST3 and resume previous music feed. Mic volume not affected.
Music fade: Option to next music feed and then unit will fade between sources after short delay.
Zone lock: Allows buttons to be disabled for a particular zone. LED corresponding to the button locked will be turned off.
