Neumann KK 104 A Cardioid Condenser Capsule Head - Nickel

Neumann KK 104 A Cardioid Condenser Capsule Head

The Neumann KK 104 A cardioid condenser capsule head brings Neumann true-condenser vocal performance to compatible Sennheiser handheld wireless transmitters. Available in Black and Nickel, it combines a tight cardioid pickup pattern, 40 Hz to 20 kHz response, 154 dB maximum SPL capability, integrated shock isolation, and built-in pop protection for professional wireless vocals and speech.

Designed for touring vocalists, presenters, broadcast production, houses of worship, theater, and live events, the KK 104 A fits Sennheiser Spectera, EW-D, EW-DX, Digital 6000, and Digital 9000 handheld systems. Its cardioid response maintains strong rear rejection while remaining relatively forgiving of performer positioning and head movement. A fixed low-cut filter compensates for proximity effect during close vocal use.

The capsule uses technology derived from Neumann's KMS wired stage microphone series and is engineered for demanding performance environments. A hardened-steel headgrille surrounds an internal pop screen that reduces plosives, helps control sibilance, and limits moisture reaching the capsule. Both Black and Nickel versions share the same acoustic performance and wireless-system compatibility.

Key Features

• True Condenser Capsule: Delivers detailed transient response and extended vocal clarity for professional wireless performance applications.
• Tight Cardioid Pattern: Focuses pickup toward the performer while providing strong rejection of sound arriving from the rear.
• 154 dB Maximum SPL: Handles powerful vocal sources without exceeding the specified 0.5% distortion threshold.
• Fixed Low-Cut Filter: Compensates for proximity-effect buildup during close vocal miking for clearer low-frequency reproduction.
• Integrated Shock Mount: Reduces handling noise before vibration reaches the condenser capsule.
• Built-In Pop Protection: Controls plosives and sibilance while helping protect the capsule from moisture during stage use.
• Modern Sennheiser Compatibility: Supports Spectera, EW-D, EW-DX, Digital 6000, and Digital 9000 handheld wireless systems.
• Black and Nickel Finishes: Offers two manufacturer-confirmed color variants with identical core acoustic specifications.

True Condenser Performance for Wireless Vocals

The KK 104 A uses Neumann true-condenser capsule technology rather than a conventional dynamic element. Its 3 mV/Pa sensitivity and 40 Hz to 20 kHz response support detailed vocal reproduction, while the transient response suits singers and spoken-word performers who require articulation from a wireless handheld system.

Cardioid Pickup with High Feedback Resistance

The frequency-independent cardioid pattern provides substantial rejection at 180 degrees while maintaining controlled off-axis response. This directional behavior helps reduce unwanted stage bleed and improves usable gain before feedback with conventional stage monitors while remaining suitable for in-ear monitoring workflows.

Built for Close-Miked Stage Performance

A fixed low-cut filter counteracts the bass increase caused by close vocal positioning. The hardened-steel grille contains an effective internal pop screen that limits plosives, controls sibilance, and helps keep moisture away from the condenser element during demanding live performances.
