Sennheiser MKE 40-4 Cardioid Lavalier Microphone (3-Pin Lemo)

High Gain-Before-Feedback Speech Audio: Sennheiser MKE 40-4

The Sennheiser MKE 40-4 is a professional cardioid clip-on lavalier microphone designed for presenters, speakers, broadcast journalists, and live theater performers operating in acoustically challenging or loud environments.

Unlike omnidirectional lavaliers that pick up surrounding ambient room noise and stage monitor bleed, the MKE 40-4 features a directional cardioid pickup pattern. This provides maximum side and rear attenuation, ensuring high gain-before-feedback when performing close to PA speakers. Available now in our Sennheiser pro audio store catalog, this version is terminated with a 3-pin Lemo connector specifically tailored for Sennheiser high-end wireless transmitters.
