MAX4466 based microphone amplifier breakout Lownoise, quality amplification: uses the MAX4466 opamp designed for delicate microphone signals with supply noise rejection for clearer sound and less hiss compared with many mic amp breakouts. Adjustable gain: backside small trimmer pot lets you set gain from 25x to 125x, enabling precise calibration for different mics and environments. Readytouse hardware: fully assembled and tested breakout with a 2020 kHz electret microphone soldered on, providing an integrated, readytorun mic solution. Compact, purposebuilt design: a purposebuilt electret microphone amplifier suitable for a range of audio applications, with reliable performance from a small breakout board. Practical applications: ideal for voice changers, audio recording and sampling, and audioreactive projects that require a reliable mic preamp. Key attributes: MAX4466 based preamp, low supply noise, adjustable gain, premounted electret microphone, 20 Hz–20 kHz frequency response, fully assembled and tested. Use scenarios Voice changer or voice effects device: use with DSP or microcontroller workflows to capture clean voice signals and apply processing with adjustable gain to suit different voices and distances. Portable audio recording or sampling: provides a clean mic input with configurable amplification, helping to optimize signal level for recording or field sampling. Audioreactive installations: captures a wide frequency range for responsive lighting, art installations, or interactive projects that react to sound.
