AWA14602(A) High-Fidelity 1/2" Preamplifier

High-fidelity signal transfer: near-lossless gain (-0.2 dB) and low distortion ensure the microphone's true acoustic signal is faithfully preserved through the preamp stage

Superior impedance matching: extremely high input resistance combined with low input capacitance minimizes loading effects on the microphone capsule, maximizing measurement accuracy

Long-distance measurement capability: low output impedance supports driving long cables in field or industrial test setups without significant signal loss

Ideal for professional acoustic testing: well-suited for applications such as sound level metering, noise/vibration analysis, and acoustic calibration where accuracy and signal integrity are critical
