Overview

The Sennheiser MMD 945-1 is a replacement and upgrade capsule designed for use with Sennheiser's evolution wireless handheld transmitter systems, including the SKM 2000. It features a super-cardioid dynamic element that delivers a tightly focused pickup pattern, capturing the vocalist's voice with clarity while aggressively rejecting ambient noise and monitor bleed from off-axis sources. This makes it particularly effective in loud live environments where feedback control is critical.

The capsule threads onto compatible transmitter bodies in seconds without tools, making it ideal for touring situations and multi-act events where quick changeovers are essential. Its smooth, uniform frequency response — both on-axis and off-axis — ensures that the vocal tone remains natural and consistent even as performers move around the microphone. With a rugged dynamic element rated for high sound pressure levels, the MMD 945-1 is built for the demands of professional sound reinforcement, from concert stages to conference halls.
