Bogen ANS501 - Manual (Page 4)

Description
The Bogen Model ANS501 Ambient Noise Sensor is designed to electronically adjust the level of a page announcement
or background music in an area of a building where ambient noise levels are continuously changing. It ensures that page
announcements or background music are intelligible even during periods of high ambient noise levels.
The ANS501 monitors the ambient noise level through the use of an ANS500M sensor microphone module. Each sensor
microphone module includes an adjustable mounting base for precise positioning.
One microphone and one power supply are included with the ANS501. Additional microphones may be purchased
separately. The control unit is capable of supporting up to four (4) microphones wired in parallel. Wire runs between the
control unit and microphones consist of two-conductor cable and can reach 2,000 feet (with 20AWG wire) with no
appreciable loss of signal strength.
