The CRY575 microphone power supply is a three-channel transducer power module. Channels 1 and 2 provide a constant current source required for IEPE (Integrated Electronic Piezoelectric) preamplifiers, while channel 3 provides power for single-ended preamplifier operation. It features high input impedance, low output impedance, low background noise, and a wide frequency response range.
The CRY575 microphone power supply offers gain options of 0dB (×1), +20dB (×10), and +40dB (×100) for the output signal. It utilizes a BNC interface for the output connection, making it easy to use.
