Sennheiser ME 9004 Cardioid Condenser Microphone Capsule (Matte Black)

The Sennheiser ME 9004 (Article Number: 502588) is a reference-grade, permanently polarized condenser microphone capsule module engineered specifically for Sennheiser's premier digital wireless ecosystems. Tailored exclusively for use with the flagship SKM 9000 and standard touring SKM 6000 handheld transmitters, this master-tier capsule is built to deliver studio-quality vocal clarity under intense live concert and broadcast conditions.

Featuring a tight, feedback-defying cardioid polar pattern, the ME 9004 emphasizes vocal performance with absolute transparency while engineering out the pop and physical handling noise that usually challenges high-gain condenser capsules on stage.

Key Acoustic and Engineering Attributes

• Patent-Pending Internal Studio Shockmount: Unlike standard live vocal capsules that mount rigidly to the housing, the ME 9004 features a unique internal suspension design. It suspends the condenser element much like a large-diaphragm studio microphone, decoupling physical stage gestures and dropping mechanical handling noise to negligible levels.

• Acoustically Optimized Plosive Shielding: Built with an advanced multi-layered head basket array accompanied by specialized internal foam inlays. This network diffuses sudden wind spikes and explosive vocal plosives (p, b, t) without introducing any mud or dullness to the upper-frequency response.

• Flagship Digital Native Transducer: Specially voiced to work harmoniously with the uncompressed HD digital transmission architectures of the Digital 9000 and Digital 6000 lines, ensuring pristine transient response and flat tracking from 40 Hz up to 20,000 Hz.

• Massive Sound Pressure Threshold: Capable of tracking screaming vocal transients, sudden acoustic swells, and close-mic high-SPL delivery up to 145 dB SPL completely cleanly without squaring off, overloading, or introducing harmonic distortion.

Production Deployment and Modular Fitting Advice

Inspecting the Concentric Contact Plate: The ME 9004 uses a multi-ring concentric conductor plate at its base to send audio data and draw phantom voltage from the SKM handle. Before screwing the module down, verify that these gold paths are entirely free of oils or moisture. Thread the head gently onto the transmitter handle strictly by hand until it fits flush—never force it or employ mechanical tools, as over-torqueing can irreversibly warp the internal contact mechanism.

Maintaining Internal Foam Inlays: Because condenser diaphragms are highly sensitive to microscopic debris and moisture build-up, heavy touring use demands periodic maintenance. The capsule ships with a set of 5 replacement foam inlays. If the vocal track begins to show subtle high-end dullness due to moisture accumulation after consecutive energetic shows, carefully unscrew the mesh grille, swap out the damp or makeup-stained inner foam inlay for a fresh one, and store the old inlay to dry.
