CRY3543 1/4" Preamplifier, IEPE, Microdot Connector
CRY3543 1/4" Preamplifier, IEPE, Microdot Connector
The CRY3543 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.
By converting high-input impedance to low output impedance, the CRY3543 allows the use of longer extension cables. It offers exceptionally low background noise, ensuring minimal impact on the microphone’s performance. Its TEDS functionality further enhances efficiency by reducing test time. With a robust design and high durability, it is well-suited for a broad range of environmental conditions.
