PROFESSIONAL SOUND CLARITY: with -70dB noise rating you'll be able to cut through the mix without adding feedback or unwanted hiss and hum. LIVE SOUND AT ITS BEST: The MB-1 preamp is durable enough for the stage, and quiet enough for the studio. For live sound, you can reduce line noise on long cable runs and improve the gain before feedback ratio for public speakers or singers. MIC PREAMP FOR STUDIO AND BROADCAST RECORDING: Boost the signal of quiet instrument sources like vocals, percussion or acoustic instruments, while maintaining the natural sound of your microphone. (DOES NOT WORK WITH CONDENSER MICROPHONES). USES 48V PHANTOM POWER: Professional dynamic microphone preamplifier that uses 48V phantom power to add 25dB of clean gain to dynamic and ribbon microphones while dropping the noise floor to an astonishing -70dB. (Note: phantom power is required and must be supplied by your audio interface or an external 48v power supply. The MB-1 does not supply phantom power).
