CCP stands for “Constant Current Power” and describes G.R.A.S. power supplies that maintain a constant level of current for driving CCP transducers such as G.R.A.S. Preamplifiers Type 26CB (¼") and Type 26CA (½"), as well as the G.R.A.S. Array Microphones.
Since current is constant, the only thing that can vary with an CCP transducer under excitation is the supply voltage.
Furthermore, since power is supplied via the same line as that used by the signal, only a co-axial cable is needed for connecting the transducer to the power supply and subsequent analyzer.
