Sennheiser electronic GmbH & Co. KG · Am Labor 1 · 30900 Wedemark · Germany · www.sennheiser.com
Sennheiser‘s best dynamic mic for live vocals just got better. The super-cardioid MD 431 II has a custom-tailored frequen-
cy response to achieve added transparency. A nearly frequency-independent polar pattern offers incredibly high gain be-
fore feedback and provides uncolored off-axis response. Its new rugged housing has a steel-mesh grille, a shock-suspen-
ded capsule, and a hum-bucking coil. It features a noiseless, magnetic reed on/off switch which is recessed in its handle,
and internal electronics for refining proximity effect.
FEATURES
• Exceptionally good feedback rejection
• Shock mounted capsule provides very good rejection of
handling noise
• Hum compensating coil
• Integral pop filter
• On/off switch (reed switch) can be locked in the ‚ON‘
position if required
