The AMPERES' AV7200 is a localised auto volume controller. Instead of sending back control data to the rack for volume adjustment, this public address system varies the speaker volume at 100V line level. As a result, it can be used in existing installations to control speaker loads of up to 100W. Shopping malls, transportation stations, and public building lobbies are examples of suitable installation locations.
Features:
Attenuation at 100V speaker line
Adjustable noise sensitivity
Built in overriding relay
Easily refit to existing installations minimizing cable rewiring
