The Mx005 is a unit which comprises a preamplifier fed by a constant current ICP® (PA-05) + microphone (P-05).
The CESVA PA-05 is fed by 2-20 mA of constant current.
The PA-05 has been specifically designed to condition the CESVA P-05 microphone. Because of its low output impedance the PA-05 allows you to use very long low cost coaxial BNC-BNC connection cables.
The Mx005 has an excellent frequency response and low noise.
