Page 4: Description
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. -
Page 5: Panel Descriptions
4. Balanced Input - High-impedance electronically balanced input (pluggable screw terminal). 5. Sensor MIC Input - Input connections for ANS500M sensor microphone(s) (pluggable screw terminal). 6. Defeat Input - The effects of the ANS501 will be defeated when these terminals are shorted together (plug- gable screw terminal). -
Page 6: Sensor Microphone Connections
Wiring Multiple Microphones Physical connections can be made using either Home Runs back to the ANS501 from each sensor mic or by daisy- chaining sensor mics, depending on the installation.The maximum total wire length from any sensor mic to the ANS501 must be kept below 2000 ft. -
Page 7: Operation
Threshold Controls Activity threshold is set just above typical operating level of the program material applied to the gain processing stage of the ANS501.Ambient threshold adjusts the ambient noise input threshold from 64 dBspl to 112 dBspl. Front Panel Switches and Indicators Mode Switch The Mode switch can be set to “Run”... -

Low-impedance unbalanced RCA output. Signal gain responds to ambient noise changes. AUX Input Mono summing, stereo, unbalanced RCA inputs. This input bypasses the gain adjustment process of ANS501 and is fed directly to the output, via the AUX level control. -
Page 9: Module Setup
It is often undesirable to have the background music level increase as ambient noise increases since it only adds to the overall noise in the area.The ANS501 provides an Aux input that bypasses the gain adjustment process so that it does not change with ambient noise levels. -
Page 10: Normal Mode
Module Setup, cont. Normal Mode All sources are affected by the gain adjustment process. Background music source will need to be routed through the main mixer inputs, which will be affected by the gain adjustment process. Refer to page 12 for illustration. Start with all POTS turned fully clockwise (AUX IN is not used in this mode). -
