CRY3541 1/4″ Preamplifier, IEPE, SMB Connector
The CRY3541 is a constant-current power preamplifier that can be used with the CRY3000 series 1/4 inch prepolarization measuring microphone and is widely compatible with other brands.
Seamlessly converting high input impedance to low output impedance, the CRY3541 enables the use of longer extension cables without compromising performance. Its low background noise ensures minimal impact on the microphone, while TEDS functionality speeds up testing processes. Designed for durability and resilience, it performs reliably across various environmental conditions.
