Low Voltage Microphone Preamplifier with Variable Compression and Noise Canceling

https://www.electronics-lab.com/project/low-voltage-microphone-preamplifier-with-variable-compression-and-noise-canceling/

This is a complete microphone signal conditioning project. Designed primarily for voice-band applications, this project provides amplification, limiting, variable compression, and noise gate. User-adjustable compression ratio, noise gate threshold, and two different fixed gains optimize circuit operation for a variety of applications. This is a complete and flexible solution for conditioning condenser microphones for personal […]
