Hangzhou Crysound Electronics Co., Ltd. MIC power CRY575

CRY575 MIC power is a three-channel microphone power module that provides a constant current source for the IEPE preamplifier, as well as the positive/negative power for the dual-power supply preamplifier. It is featured by high input impedance, low output impedance, low noise floor, and wider frequency response range. It can be used with CRY506 IEPE Preamplifier and CRY502 Preamplifier, and can also be compatible with the preamplifiers of other brands. CRY575 MIC power provides 0 dB (X1), 20 dB (X10), and 40 dB (X100) gain for output signals. The output interface uses the widely-used BNC port, so enabling users to easily connect to the input terminals of general instruments. CRY575 Front Panel Gain adjustment switch (×1/×10/×100): Individual gain adjustment for each channel signal; three steps: 0 dB (×1), 20 dB (×10), 40 dB (×100) LED power indicator (POWER): It will light up when the instrument is in normal operation. Signal output channel (CH OUT): It uses a BNC port. Signal input channel (CH IN): It uses a BNC port for use with the ICP preamplifier. CRY575 Rear Panel Power grating switch and gain multiplexing switch (ON/OFF) / (x10/x1/OFF): Three-terminal toggle switch; when the OFF terminal stops working, ON (x1) will occur on one end; when the instrument is powered on successfully, ON (x10) will occur on one end; Channel 3 gain can be selected simultaneously. Power input: USB and 5 V power adapter are available in two ways (they cannot be used simultaneously). Signal input channel (CH2B IN): DB9 port for use with a dual-power supply preamplifier Technical specifications of CRY575 Frequency response range: 10Hz ~ 60kHz (±0.5 dB) Input impedance: 1MΩ Output impedance: 100Ω Noise floor: -90 dBV ICP constant current source: 24V/4mA Gain: 0dB(×1)，+20dB(×10)，+ 40dB(×100) Port type: BNC, DB9 Operating voltage: 4V～8V Dimension (mm): 69×154×120（L×W×H) Applicable temperature range: -30°C ~+70°C
