The MMD 945-1 cartridge from Sennheiser delivers high-performance audio and road-tested dependability at a competitive price. Able to handle high sound pressure levels and effective at rejecting feedback, this cartridge promises crisp, clean sound and high gain before feedback even on loud stages. Whether you're setting up a single live mic for a small show or using several mics onstage in a large concert hall, the MMD 945-1 is a solid choice. This cartridge is compatible with Sennheiser SKM 100/300/500 G3, SKM 2000/6000/9000, SKM D1/AVX, and SL handheld wireless transmitters.
