CRY3502 1/2″ Preamplifier, IEPE, SMB Connector, Very Short
CRY3502 is a short constant current power preamplifier. It can be used with the CRY3000 series 1/2 inch prepolarized measurement microphone and is widely compatible with other brands.
CRY3502 converts high input impedance to low output impedance, allowing the use of a longer extension cable. The advantage is that the background noise is low and it hardly causes a load on the microphone. It supports the TEDS function and reduces test time. The compact design enables it to measure in environments with limited space.
