Microphone capsule Sennheiser MMD 845-1 supercardioid — compatible with EW 335, SKM 300-835 G3

Sennheiser MMD 845-1 is a supercardioid microphone capsule designed for handheld wireless transmitters such as EW 335 and SKM 300-835 G3. The capsule offers a focused polar pattern and tailored frequency response for clear vocal reproduction, reducing pickup of ambient noise and stage bleed. It functions as a direct replacement or upgrade for compatible Sennheiser handheld systems and is suitable for live performance, presentations and broadcast use.

Advantages

The supercardioid polar pattern provides enhanced off-axis rejection and improved feedback resistance compared with cardioid designs. The capsule delivers consistent vocal clarity and presence across typical speech and singing ranges, while its mechanical and acoustic design minimizes handling noise. Compatibility with common wireless transmitters allows quick installation and straightforward interchangeability.

Suitable for

• Live vocal performances on stage
• Spoken word and presentations in conferences or houses of worship
• Broadcast and streaming applications requiring focused pickup
• Replacement or upgrade of compatible handheld wireless transmitters

Key specifications

• Polar pattern: supercardioid for tight frontal pickup and reduced side/rear sensitivity
• Intended use: handheld vocal capsule for wireless transmitters
• Frequency response: tailored for vocal clarity (neutral-to-present midrange)
• Construction: robust metal capsule housing designed for stage use
• Noise control: designed to minimize handling noise and vibration artifacts

How to use

To install the MMD 845-1 capsule, remove the existing capsule from the compatible handheld transmitter following the transmitter manufacturer’s instructions, then securely attach the replacement capsule until it is seated. Position the microphone capsule 5–15 cm from the mouth for spoken voice or adjust distance according to desired proximity effect for singing. Maintain a consistent angle toward the sound source—on-axis placement provides the best tonal balance and rejection of background noise.

Usage recommendations

For optimal results, pair the capsule with a properly adjusted wireless transmitter gain and use basic stage microphone technique: keep the capsule pointed at the sound source, avoid covering the grille, and allow a short warm-up before critical use. When used in high-SPL environments, monitor for potential proximity boost and adjust distance or EQ as needed.
