A RAD17 provides a single audio input from a built-in omnidirectional boundary layer / PZM pressure zone electret microphone. It handles extreme temperatures and humidity for indoor or outdoor applications. It may be used for ambient noise sensing, surveillance, security, train stations, etc. The RAD17 mounts in a standard 1-gang US electrical box. It is only available in black, though the metal grille may be spray painted to match surroundings. A black Decora™ plate cover is included.

• Ambient Noise Compensation

  Halogen’s ANC block combined with the RAD17 (or any) omnidirectional microphone allows the crowd noise to control the background music and paging volume. Background music and paging should only be loud enough to be heard — not blasting in the morning, or too quiet at night. As the crowd gets louder, music and paging gets louder. Less customer complaints about sound, faster service at the shoe counter.
