ETMC Technologies :: G.R.A.S. Sound & Vibration :: Type 26CA - A 1/2" preamplifier for connection to G.R.A.S. CCP input channel , e.g. see Type 12AL. The Type 26CA has a standard BNC output connector and is for use with prepolarised microphones. It is delivered without a cable. The built-in TEDS2 chip enables it to be programmed as a complete unit together with a microphone.
