Sound limiter Control
This unique "Noise Monitoring System" is designed to protect the valuable licence in places of public entertainment. This clever unit continuously monitors the pre-set sound level. As the noise level approaches the set level a warning light will illuminate. Once the set level is exceeded, any mains supply connected through the unit will be disconnected (Usually the mains sockets on stage, into which visiting bands or discos connect). The power remains disconnected for a period that you set. If the venue has a sound system permanently installed, then an additional interface can be added (G920C) that automatically turns down the sound system, without disconnecting the mains supply. A remote indicator panel (G920B) is available for mounting "on stage" or in the "DJ box" to enable the performers to see when they are in danger of being disconnected. Up to four indicator panels may be connected to one G920A control unit.
