PLACID preamplifier PNP2122-S

Design
All PLACID ICCP microphone preamplifiers are designed for ¼”, ½” and 1” condenser microphones. The preamplifiers are optimized to have a flat frequency response which will ensure high quality acoustic measurements.

Self Noise
The electrical circuit has especially been designed to ensure a low self‐noise level which typically be much lower than the self‐noise of the microphone cartridge.

Impedance
The PLACID PNP21 input impedance is over 5 Ω, the output impedance is less than 110 Ω .
