Low Noise Microphone Preamplifier

Low Noise Microphone Preamplifier

This is a design for a low noise microphone preamplifier, which is ideally suited to low impedance microphones. One limitation is that it is not balanced, which is not a problem in a home recording environment, but will allow the mic lead to pick up noise with long cable runs or in a hostile environment.

Portable Microphone Preamplifier

Portable Microphone Preamplifier

This circuit is mainly intended to provide common home stereo amplifiers with a microphone input. The battery supply is a good compromise- in this manner the input circuit is free from mains low frequency hum pick-up and connection to the amplifier is more simple, due to the absence of mains cable and power supply.
