Ezi-Listening
Ambient Noise-Sensor Level Regulating Module ANS-1A
Monitors ambient noise
ANS-1A is designed to receive audio signals from an ambient sensing microphone to adjust signal levels to the power amplifier of the Public Address installation, to ensure announcements are always heard.
XLR Interface Connection
Easy 'plug and play' installation
Inserts between System preamplifier and power stages
Very simple to implement
Pre-install Planning document available
Ezi-Listening is perfect for train station platforms, airport departure lounges, supermarkets, stadia tc.

Ambient Noise Sensor
Level regulating/ambient noise following module type ANS-1A is designed to receive audio signals from an ambient sensing microphone and use these to adjust signal levels to the power amplifier of the Public Address installation.
The output level of the module will automatically and constantly adjust to follow the averaged rise and fall in ambient noise in the area served by the host amplifier (airports, hotel reception areas, transport termini, sports stadia, etc.) The ambient noise will be continuously sampled by the sensing microphone/s, sited as close to the sources of change as possible.
Working Together
Where large areas have various localised sources of variable ‘ambient’ noise, it may be desirable to cover each with a separate sensor; for example, an underground railway tube would benefit from having one sensor at each end to detect the noise of trains arriving from either direction.
Planning Support
A pre-install planning document is freely available for a full understanding of the concept of ambient noise sensing. It is recommended that a copy is obtained from our Sales Office.
