4.3 Priority input
You can connect other devices or systems to the priority
input. The priority input has a higher priority than
audio input 1 and audio input 2. When the priority
input receives a signal, the loop amplifier replaces the
signal on the connected induction loops with the signal
of the priority input.
For example, you can connect a Plena Voice Alarm
System (refer to figure 4.3) to the priority input.
