CRY3503 1/2" Preamplifier, IEPE, Microdot Connector, Very Short
CRY3503 1/2" Preamplifier, IEPE, Microdot Connector, Very Short
CRY3503 is a 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.
CRY3503 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.
- High input impedance, low output impedance
- 10-32UFN(Microdot/M5) Interface
- Supports “Smart Transducer Interface” IEEE 1451.4 containing TEDS
- Low background noise
