Description

MICROPHONE AMPLIFIER - A KIT FOR INDEPENDENT INSTALLATION

The universal microphone amplifier can work directly with popular 2- and 3-terminal electret microphones. Very good sound quality has been achieved: thanks to the use of high-performance components: tantalum capacitors and the NE5532 low-noise operational amplifier. Thanks to this, the module has such good parameters that it is perfectly suited to working with good quality dynamic microphones.

The device is especially recommended for electroacoustics and musicians
