A general purpose AC coupled amplifier with a selectable modulation ...
These G.R.A.S. microphone preamplifiers are small robust units optimised for acoustical measurements with condenser microphones.
Connections to preamplifiers are most often made via a 7-pin LEMO series 1B connector; unless its a CCP* Preamplifier. These connectors (see diagram on the right) are widely used, ensuring compatibility with a wide range of power supplies, analyzers ...
