AWA14600E Dual-Polarization 1/2" Low-Noise Preamplifier

Ultra-Low Noise Signal Amplification: With self-noise as low as ≤3 μV (A-weighted), ensures extremely clean and accurate signal transmission for precision acoustic measurements.

Wideband High-Fidelity Performance: Supports a broad frequency response up to 200 kHz, delivering accurate signal reproduction for advanced laboratory and high-frequency applications.

High Input Impedance Design: ≥10 GΩ ultra-high input impedance minimizes signal loading and ensures measurement accuracy and stability.

Low Distortion, High Linearity Output: Total Harmonic Distortion (THD) ≤0.1% guarantees faithful signal amplification with minimal distortion.

Compatible with Multiple Microphone Types: Supports both 1/2-inch prepolarized microphones and 200V polarized microphones, providing flexible system integration.
