Versatile Preamplifier Series | ICCP Tech for All-scenario Acoustic Testing
2026-05-22Excellent Signal Processing
Serving as signal converter, it reduces microphone impedance from GΩ level to under 30Ω, enabling sound cards and collectors to capture acoustic signals clearly.
Single coaxial cable realizes 24V constant current supply and signal transmission, getting rid of complicated 4-wire connection and external interference.
Performance Upgrade by ICCP Technology
ICCP (Integrated Constant Current Power) greatly optimizes preamplifier performance with integrated power and signal design.1
It integrates power supply and signal output into one cable for simpler wiring. Stable operation only needs 2-20mA constant current input, no extra polarization voltage required, lowering system complexity and cost.
Great long-cable compatibility keeps minimal signal attenuation even in hundreds-meter transmission, securing intact and accurate data for remote distributed measurement.
