Preamp module designed to bring a small input signal up to a suitable level to drive an audio amplifier. Use with our 3017KT to produce full power output or our 3-Input Mono Mixer kit 1052KT.
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.
~ 100 mV RMS (gain = 27 dB)

~ 70 Hz to 45 kHz ±3 dB (Standard setup)
< 0.1 % at 1V 1kHz
40dB max. (see Product Documentation link below for details)
