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.

An elegant solution to low output mics

Brings my ribbons to life. Bumblebee RM-5's through my custom nuvistor mic preamp. Must be heard to be believed. Well done, DIYRE!

Great kit

Super easy build, works great with my Beyer M160, nice boost with no noise.

Works as Advertised

This kit takes about 2 hrs to build. After that you have a two channel in line amp for use with dynamic and ribbon mics. I have been using it on a Shure SM7 and a Royer R10 for about a week and it works just as advertised.

Excellent!

I use the AEA R88 and R84 for most of my work. Typically I run them into the RPQ2, but the MB2 gives me the option of running the mics into my SCA J99 as well, with no mud or loss of high end. I may actually prefer these ribbons going through the MB2 into the J99 than straight into the RPQ2, though both options are excellent.

Hi Q in a Low Q world

It was so easy! Great parts and board layout, works exactly as it should.
The instructions are written in a casual conversational way, and that really adds a reassuring element to the build experience.
Of course as a first rate geek I’d enjoy a specs sheet.
