Barrier strip connections for sensor microphone & remote defeat

The ANS1R Ambient Noise Sensor from Bogen 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.
