TOA Electronics AN-001T Ambient Noise Controller Module
The AN-001Tis a plug-in module of 2-channel ambient noise detector designed for use withthe 9000 series amplifiers. It automatically adjusts the output volume inresponse to the change of ambient noise level. The AN-001T can handle inputsignals from microphone level (-60 dB) to line level (-10 dB) by controllingthe gain in 9 steps. Phantom power (+24 V) can be supplied for condensermicrophone use.
