This article will explain how to setup Line Monitoring on the speaker line on ENA Amplifiers.
Exigo has two ways of monitoring the speaker line/loops.
- Self Protection, no settings required.
- Active Line Monitoring with pilot tone. This requires setup in EMT and on the ENA Amplifier.
Self Protection
There is two mechanisms that are used for self protection:
- Short on the line. If the speaker line is shorted the amplifier will shut down.
- High temperature. Before the amplifier shuts down it will first reduce the audio by 6 dB. If the temperature keep on rising it will eventually shut down.
Active Line Monitoring
Each ENA amplifier can be independently monitored for impedance changes. This is used to detect fault such as load change, open/short and ground faults.
