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 of extra gain with ultra-low noise and distortion.

The MB2’s high input impedance is optimized to capture the full audio spectrum of ribbon mics without damping the ribbon. And MB2’s buffered, low-impedance outputs are great for driving long cable runs without noise or gain loss.

Superior specs. Don’t be fooled by the low price—the MB2’s premium parts and no-compromise design make for better specs than the leading inline mic boosters.

Simple and useful

Totally worth the time and money to gain up my ribbon mics for quiet sources.

Great studio tool

The build is quick and easy. The sound quality is great. Great value all around. The only downside is that the housing isn’t as robust as other offers, but it’s still good. If you take care of it, I’m sure it will serve you well for a long time.

MB2 Stereo Mic Booster

Just do what it does and does it perfectly. Good for dynamic mics but also for passive DI box like the FE2. Easy to build and sounding very quiet and transparent. Thank you !

Perfect

Great features, super easy to build. Great component quality. Eco friendly packaging.

As always, I am super happy with my DIY RE product. The only downside… lots of people love them and they tend to be often out of stock.

As always a great product

Amazing value and performance!

This kit was a breeze to build and sounds great. Paired with my AEA R88 it’s killer!
