CRY547 Preamplifier
1/4'', IEPE power supply, SMB port
CRY547 Preamplifier is paired with a pre-polarization 1/4" measurement microphone,and featured by high input impedance, low noise floor, and a wide frequency response range.It can be used with CRY300 series 1/4'' pre-polarization measurement microphones and is also compatible with other brands of measurement microphones, such as B&K and G.R.A.S. CRY547 preamplifier is suitable for wide operating temperature and humidity.Its low output impedance can support long distance transmission.Preamplifier, cable and connector meet EMC requirements, bandwidth can up to 80kHz .
