TOA AN-001T M-9000 Series Ambient Noise Controller Module
The AN-001T is a plug-in module of 2-channel ambient noise detector designed for use with the M-9000.
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.
