AS3098KT - Mono Preamplifier Board (Electret MIC, Audio & Guitar Versions)
Pre-Assembled and Kit versions availableMade in Britain

This preamp board can be used with the electret microphone supplied or to bring a small input signal up to a suitable level to drive an audio power amplifier. Use with our 3017 - 1W Mono Audio Amplifier Board to produce full power output or our 1052 - 3-Input Mono Mixer Board or your own equipment.

Delivering a minimum gain of 40dB, this is normally more than enough for most applications. Gain can be increased by simply changing a single resistor value. See kit documentation below for full details.
