CRY502 Preamplifier

1/2'', dual / single power supply, with cable and DB9 port

CRY502 Preamplifier is paired with a pre-polarization 1/2" measurement microphone for impedance conversion and preamplification. It is compatible with 1/2" measurement microphones from such suppliers as B&K and GRAS and can be connected to piezoelectric ceramic vibration transducers. The preamplifier can be connected to a 1/2'' measurement microphone and is featured by high input impedance, low output impedance, low noise, and wide frequency response range. It is suitable for electroacoustic test systems, multi-channel noise analysis and other applications.
