High Power Amplifier (HPA)

The most difficult and problematic area of fire station audio is the apparatus bay. Westnet's highly successful solution to this problem is the First-In High Power Amplifier®. Westnet's Dynamic Audio Technology alleviates the problem of missed calls due to inaudible dispatch transmissions in high-noise environments, such as stations located at airports, military bases and industrial areas. When station noise levels are high, the HPA automatically increases its speaker volume. Similarly, when station noise levels are low, the HPA softens its speaker volume, allowing personnel to comfortably hear the alert and dispatch audio. The HPA is placed in high noise level areas such as apparatus bays and outside yards.
