The SENNHEISER's MMD 945-1 supercardioid dynamic voice microphone delivers high-performance audio and road-tested dependability at an affordable price. This dynamic microphone cartridge promises crisp, clean sound and strong gain before feedback even on loud stages, as it can tolerate high sound pressure levels and is effective at rejecting feedback. The MMD 945-1 is a good choice whether you're setting up a single live mic for a small event or using multiple mics onstage in a huge concert venue. Sennheiser SKM 100/300/500 G3, SKM 2000/6000/9000, SKM D1/AVX, and SL portable wireless transmitters are compatible with this cartridge.
