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.

Customer Reviews
I've got some less expensive MXL mics with re-tensioned ribbons. The only way I've ever gotten them to sound "good" in a mid-side configuration is with the MB2. It lowers the noise floor considerably, even when using with the CP5s in my Colour Duo!
I love mic boosters concept. I own Soyuz boosters, which adds lots of color and saturation. So this MB2 is a great addition to my mic tools arsenal as I wanted another clean mic booster. It was easy to solder / assemble it. As I said I compared it with my Soyuz boosters and remained very pleased with the result. It's same amount of gain boosting and different tone (uncolored). This is my my third DIY project after two re:amp boxes and two summing boxes. I can see my soldering abilities are getting better!
The MB2 is a quick and easy build. The documentation and labeling of the PCB aid in the build process. I look forward to future builds from DIY RE.
Got this recently and built it quickly (quality is great and soldering is very easy and forgiving on these boards). Used it fine for a few days until one of the channels started buzzing more than the other. Turns out a transistor had a internally shorted. I emailed the service dept. and they sent a replacement transistor priority mail, which arrived not 2 days later. Now the product is right back to service and sounding/working great with my R88 stereo ribbon. Just an absolute pleasure doing business with this company.
Fun & easy project with great results in use. Look forward to building more from DIYRE
