Neumann KK 204 – Cardioid Capsule Module for Sennheiser Wireless

Product Overview

The Neumann KK 204 is a cardioid condenser capsule module engineered for Sennheiser SKM 500 G4, SKM 2000, SKM 6000, and SKM 9000 wireless handheld transmitters, as well as the EW G4 300/500 and EW-D wireless systems. It brings true Neumann studio-grade condenser capsule performance to the stage, with a tight, frequency-independent cardioid polar pattern that delivers high gain before feedback in demanding live environments. The KK 204 is the professional choice for lead vocalists, presenters, and broadcast talent who require studio-quality intelligibility through a wireless handheld transmitter. This nickel-finish version is mechanically and acoustically identical to the KK 204 BK black variant.

Product Description

The KK 204 cardioid wireless capsule is derived from Neumann's award-winning KMS wired stage microphone series, bringing the transient response and tonal accuracy of a studio condenser microphone to wireless live sound operation. Unlike dynamic capsules found in most stage handhelds, the KK 204 uses a true condenser element that captures vocal detail, consonant clarity, and upper-harmonic content without the need for aggressive EQ boosts — which itself contributes to improved feedback resistance.

The cardioid polar pattern of the KK 204 provides strong rear rejection (180°) while maintaining a wide, forgiving pickup angle from the front. This makes it well suited for performers who move the microphone or vary their distance from the capsule. A fixed low-cut filter compensates for proximity effect, ensuring accurate bass reproduction even with close-lip technique. The hardened steel headgrille incorporates an integrated internal pop screen that suppresses plosives and shields the capsule from moisture without introducing sibilance artifacts.

With a maximum SPL handling of 150 dB and a signal-to-noise ratio of 70 dB-A, the KK 204 is built to perform on the largest stages and in the most acoustically challenging broadcast environments without clipping or self-noise artifacts. The capsule screws directly onto compatible Sennheiser SKM transmitter bodies and requires no additional tools or configuration.

Key Features

• Cardioid Condenser Capsule — True condenser element based on the Neumann KMS series delivers studio-grade transient response and vocal clarity unavailable from dynamic stage capsules.
• High Gain Before Feedback — Frequency-independent cardioid pattern with strong rear rejection at 180° maintains stable operation at higher gain settings compared to wider polar patterns.
• 150 dB Maximum SPL — Handles extreme sound pressure levels without clipping, suitable for loud stage environments and high-output monitor systems.
• Fixed Low-Cut Filter — Built-in proximity effect compensation preserves accurate bass response during close-mic technique, eliminating the need for console EQ correction.
• Integrated Pop Screen — Internal hardened steel headgrille with effective moisture and plosive protection that does not introduce sibilance artifacts.
• Compatible with Sennheiser SKM 500 G4, SKM 2000, SKM 6000, SKM 9000 — Direct thread-on fit; no adapters or tools required.
• Nickel Finish — Standard nickel body finish; acoustically identical to the KK 204 BK black variant.

Typical Applications

• House of worship — lead vocals and pastoral speech in large sanctuaries with active monitor systems
• Auditorium — touring and theatrical vocal performance on high-SPL stages
• Broadcast studio — on-camera talent and presenter handheld use
• All-hands room — executive presentation in large corporate venues with wireless handheld systems
• Multi-purpose room — versatile speech reinforcement where a wide cardioid pattern suits varied presenter positions
