4 loudspeaker line control card

This card offers 4 independent loudspeaker line outlets.

Measurement of the lines can be done by 2 methods: the impedance method or LOOP method. The card detects failure of the amplifier and switches the 100 V signal between internal buses and individual amplifier input on the card. A built-in dedicated measuring component on the card monitors the status of the internal rail.
