Sennheiser MZH Drums

A Legendary Sound Capture, Modernized in a "Kompakt" Format

For over five decades, the MD 421 series has been a professional sound recording standard, heard on countless productions and performances. The MD 421 KOMPAKT continues this legacy by retaining the sonic DNA that made the model famous, while adopting a more compact form factor and a revised mounting system to meet the demands of modern setups (TV sets, stage, studio, live sessions).

This "Drum Clamp" version adds the accessory that changes everything daily: the MZH DRUMS, designed to mount the microphone cleanly on a drum shell without makeshift solutions and with true mechanical security.

Who and What It's For: Toms, Snare, Amps, and Demanding Close Miking

This microphone is aimed at drummers, sound engineers, home studio users, and live professionals seeking a precise, dense, and controllable capture of powerful sources. On a kit, it excels in close miking of toms and snare drums, especially when space around the drums is limited and mounting stability is critical.

Beyond drums, its character is well suited for capturing a guitar cabinet, wind instruments, or spoken vocals, whenever the goal is to obtain a clear, focused signal with good resistance to feedback and bleed.

Design and Features: Stability, Quick Placement, and Faithful Reproduction

Integrated Clip + MZH DRUMS Clamp: A Mounting System Designed for the Field

The integrated mounting clip on the microphone simplifies setup and reduces delicate handling. With the MZH DRUMS, the attachment is neat and reliable: the clamp positions on the drum hoop (toms, snare), and the screwed assembly provides a true "lock" to prevent slipping during play, even with strong vibrations.

Extended Response and Solid Bass Thanks to the Internal Tube

The MD 421 KOMPAKT is designed to reproduce both the impact and body of the instrument. Its internal bass tube promotes a more extended and stable low-frequency response, useful for achieving deep, clear toms without losing attack definition.

Cardioid Directivity: More Control in a Busy Mix

The cardioid pattern helps maintain focus on the targeted source, with better isolation from bleed (cymbals, other drums, stage monitors). The result: a more usable signal that fits more easily into the mix, both live and in the studio.

Built to Last

Designed to withstand intensive use, the microphone features robust construction and field-oriented choices: quick placement, mechanical stability, and professional 3-pin XLR connectivity, ideal for integrating into any standard audio chain.
