Sennheiser MD 441-U Super-cardioid dynamic with low and high equalization switches - 000762

Product Overview

The Sennheiser MD 441-U is the reference-grade dynamic microphone in Sennheiser's professional wired microphone line—a super-cardioid dynamic with a five-position low-frequency contour switch, a two-position high-frequency switch, critically damped internal shock suspension, and a hum bucking coil. It is the engineer's choice when a dynamic microphone must perform at a level comparable to a high-quality condenser, without phantom power dependency and with full-SPL handling and EMI rejection. Broadcast studios, orchestral recording engineers, and demanding live productions have relied on the MD 441-U for decades.

Product Description

The MD 441-U achieves a near-ideal super-cardioid polar pattern that remains consistent across the full audible frequency range, providing off-axis rejection that minimizes bleed from adjacent sources and maximizes gain before feedback in monitored stage environments. The five-position low-frequency contour switch provides progressive high-pass filtering at the microphone itself, covering the range from flat broadcast response to tight low-cut for close-miked brass or vocals with heavy proximity effect. The two-position high-frequency switch offers a selectable presence lift calibrated specifically to the MD 441-U's frequency response, providing upper-midrange enhancement for vocals or instruments that need to project through a dense mix without EQ at the console. The critically damped internal shock suspension reduces the transmission of stand-borne and cable-borne mechanical vibration to the capsule, providing isolation without requiring a separate external shockmount. The hum bucking coil rejects EMI from lighting dimmers, power transformers, and nearby electronic equipment. The dynamic transducer requires no phantom power and handles high SPL without a pad—a practical advantage when the mic is used near loud acoustic sources where condenser pads would limit dynamic range. For engineers who need one microphone that can address a broadcast announcer, a close-miked brass section, and a loud guitar amplifier in the same session, the MD 441-U is the appropriate tool.

Frequently Asked Questions

Q: Why choose a dynamic microphone at this price point over a condenser?

The MD 441-U is the appropriate choice when SPL handling, EMI rejection, and phantom power independence are more important than the absolute noise floor of a condenser. Broadcast studios use it for announcers near computer monitors and lighting equipment. Recording engineers use it on brass, woodwinds, and amplifiers where condenser SPL handling would require a pad that limits dynamic range.

Q: What does the two-position high-frequency switch do?

The switch adds a presence lift calibrated to the MD 441-U's specific frequency response. It is useful for vocals and instruments that need to project through a dense mix or a loud monitored stage without adding global EQ at the console. The flat position is appropriate for broadcast voice and accurate instrument recording where coloration is undesirable.

Q: How does the five-position switch on the MD 441-U compare to the MD 421-II's switch?

Both microphones offer a five-position progressive high-pass filter. The MD 441-U adds the two-position high-frequency switch, providing additional on-mic EQ flexibility that the MD 421-II does not have. The MD 441-U also uses a super-cardioid pattern versus the MD 421-II's cardioid, offering higher gain before feedback in monitored environments.

Q: Is the MD 441-U suitable for close-miked musical instruments?

Yes. The dynamic transducer handles high SPL from guitar amplifiers, brass instruments, and drums without distortion and without a pad. The five-position low-frequency switch can be used to manage proximity effect or instrument fundamental resonance at the source, reducing the workload on the console EQ.
