The ANS1R from Bogen is an Ambient Noise Sensor for use with the Power Vector amplification system. This sensor automatically adjusts the volume of the page announcement or background music in areas where ambient noise levels are changing continuously. This output module includes an unbalanced input to mitigate channel loss when using this output module. Adjustments include gain control, ramp speed control, threshold control, ambient mic input threshold control, and aux level input control. A barrier strip is used for connections with sensor microphone and remote defeat.
