Description The AN-001T (with B00 Firmware) 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 (-60 dB) to line level (-10 dB) by controlling the gain in 9 steps. Phantom power (+24 V) can be supplied for condenser microphone use. Specification * 0 dB = 1 V Power Source +24 V DC, -24 V DC, +6 V DC Current Consumption 20 mA (at +24 V DC), 20 mA (at -24 V DC), 60 mA (at +6 V DC) Input Sensor input (Ambient noise sensor microphone input): 2 channels,3 kΩ (when the phantom power is ON)/10 kΩ (when the phantom power is OFF),electronically-balanced, removable terminal block (3 pins) Input Sensitivity -60, -54, -48, -42, -36, -30, -24, -18, -10 dB* (selectable) Phantom Power +24 V DC A/D Converter 24 bit ADC Sampling Frequency 48 kHz Ambient Noise Control Function Sensor input reference level adjustment functionMaximum output signal level control: -15 to 0 dBMinimum output signal level control: -18 to -3 dBSample time setting: 10 s, 15 s, 20 s, 30 s, 1 min, 2 min, 3 min, 5 minGain ratio setting (Ambient noise: Output signal level): Operating Temperature -10℃ to +40℃ Finish Panel: Aluminum, hair-line Dimensions 35 (W) × 78 (H) × 91.5 (D) mm Weight 82 g Accessory Removable terminal plug (3 pins) …2, Module mounting screw …2 Option Ceiling mount microphone: AN-9001
