CRY512 Pre-amplifier CRY512 IEPE Pre-amplifier is a pre-amplifier powered by a constant current source. This pre-amplifier has the characteristic of high input impedance, low noise, and wide frequency response. It can be used with the CRY300 series 1/2-inch pre-polarized measurement microphone, and it’s also compatible with other brands of measurement microphones such as B&K, G.R.A.S. CRY512 pre-amplifier uses a SMB interface. With the SMB(M) to BNC(M) cable, CRY512 can connect to various kind of electroacoustic testers. The stainless steel material makes it sturdy and durable, also give it a long-term stability. CRY512 Pre-amplifier is suitable for electroacoustic testers, multi-channel analyzers and other instruments.
