AWA14601L Wide-Dynamic-Range 1/2" Preamplifier

Exceptional dynamic range coverage: 123 dB span (20–143 dB) allows accurate capture of both very quiet and very loud acoustic events within a single measurement chain

True signal fidelity: unity gain (0 dB) ensures the impedance conversion introduces no level distortion, preserving an accurate representation of the original acoustic signal

Excellent low-noise floor: single-digit A-weighted self-noise supports precise low-level sound measurement in quiet environments such as anechoic or noise-critical testing

Extended high-frequency capability: response up to 200 kHz broadens suitability beyond standard audio range into ultrasonic and specialized acoustic research applications

Purpose-built for precision acoustic instrumentation: ideal impedance-conversion front-end for sound level meters, acoustic calibrators, and other measurement-grade instrumentation using standard 1/2" condenser microphones
