Mono Preamplifier Board

AS3098KT - Mono Preamplifier Board
Ability Level 2: ModerateProduct Formats Available : Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

Preamp module designed to bring a small input signal up to a suitable level to drive an audio 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.

The circuit can also take its input from an electret microphone by simply adding a resistor, both of which are included with the kit.
