TOA AN-001T AMBIENT NOISE MODULE FOR 9000 SERIES

The AN-001T is a plug-in module of 2-channel ambient noise detector designed for use with the 9000 series amplifiers. It automatically adjusts the output volume in response to the change of ambient noise level. The AN-001T can handle input signals from microphone level (−60dB) to line level (−10dB) by controlling the gain in 9 steps. Phantom power (+24V) can be supplied for condenser microphone use.


Features

  • Automatically adjusts output gain to compensate for changes in ambient noise level
  • Each input can be assigned to control a specific output
  • Two inputs with +24VDC phantom power for condenser mics
  • 14 preset gain ratios
  • Noise sensing microphone available, model AN-9001
  • Maximum two per chassis
