The high performance BOGEN Ambient Noise Sensor Module ANS1R is a Barrier strip connections for sensor microphone and remote defeat. It is an ambient noise sensor module that adjusts the level of a page announcement and/or background music in an area of a building where ambient noise levels are continuously changing. The unit features a ramp speed control that sets the speed by which gain is added to the signal once the ambient noise level surpasses the threshold. The module possesses a 4-pin input barrier strip connector to make the input connection for the microphone and to connect a remote defeat switch.
The unit also provides stereo unbalanced RCA inputs that provide 20 k-ohm input impedance.

Features: 

• Maximum gain control

• Stereo unbalanced AUX inputs (summed
mono) with low priority
• AUX input can bypass gain control function
• AUXinput level control (active in AUXinput
processing “Bypass Mode” only)
• Compact sensor microphone (one included)
• Connect up to 4 sensor microphones for
large area coverage
• Remote defeat connections
• Gradual fade back from mute for AUX IN
