26 dB of clean gain boosts signal for ribbon and dynamic mics, ensuring optimal audio capture
Ultra-low noise and distortion for transparent, high-fidelity sound reproduction
High input impedance (10kΩ) preserves the natural audio spectrum of ribbon microphones
Buffered low-impedance outputs prevent noise and gain loss over long cable runs
Factory-matched LSK170 JFETs and metal film resistors deliver consistent, high-performance amplification

Get the most out of your ribbon and dynamic mics in the studio or for your podcast. The MB2 is a two-channel inline mic booster with better performance than more expensive competitors.
Boosted performance. Sometimes ribbon and dynamic mics need a little more gain than a typical mic preamp can provide. In these cases the MB2 provides 26dB

A pair of fancy ribbon mics can be pricy. Boosting them can be affordable!
As long as this kit is available, I'll keep buying it. This was my second time picking one up. Assembly couldn't be easier. The instructions make everything clear, but if I didn't have them I wouldn't worry, because the PCB layout has all the info on it as well.

Awesome kit. Instructions are well written and easy to follow. All components are quality. The end product works as it should and is 1/3 the cost of an assembled product from a trusted manufacturer. I own several different kits from this cendor and all are quality.
