Franklin Audio MP-10 Mic to Inst Pre-Amp

Franklin Audio MP-10 Mic preamp for running microphones into guitar pedals (with +48V)

Balanced XLR in + Mic Thru · Mic level to instrument level conversion · 12–60 dB gain · −20 dB pad · GND + polarity switches · Switchable +48V phantom · 9V center-negative · Made in Australia

The Franklin Audio MP-10 is a compact microphone preamp built for one purpose: letting you plug any microphone into any pedal with proper level, impedance, and gain staging. It converts low-level mic signals into instrument-level output for pedals, and provides switchable +48V phantom power for condenser mics when needed.

It’s made for both stage and studio workflows. Run vocals or mic’d instruments through your pedalboard (delay, chorus, fuzz, anything), while preserving a clean feed via the balanced Mic Thru—perfect for sending a dry signal to FOH or capturing a clean track alongside your effected chain in the studio.

MP-10 offers 12–60 dB of gain, with clear status LEDs and practical utility switches: −20 dB PAD for hot sources, GND to reduce hum from ground loops, and polarity (Ø) to invert phase when required. Power it from standard 9V center-negative pedal power.
