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.

	($150/channel)	($90/channel)	MB2 ($50/channel)
Output Impedance	6.8kΩ	6.7kΩ	10kΩ
Distortion (THD+N)	.01%	.038%	.005%
Noise (EIN)	-122dBV	-122dBV	-127dBV
Gain	10-26dB*	12-27dB*	26dB
