Description
ZT-507 ICP Preamplifier is powered by constant current source and featured by high input impedance, low noise floor, and a wide frequency response range. It can be used with ZT-300 series 1/2'' pre-polarization measurement microphones and is also compatible with other brands of measurement microphones, such as B&K and G.R.A.S. The output interface uses a BNC plug, which can be easily connected to the input terminal of a general instrument. This product is made of stainless steel, which gives it good toughness and makes it suitable for long-term storage. It is applicable to electroacoustic testers, multi-channel analyzers and the like.
