Overview

The Sennheiser EW 500 G4 with Neumann KK 205 capsule is a professional wireless microphone system that combines Sennheiser's proven G4 UHF platform with a Neumann-designed super-cardioid condenser capsule head — a pairing that elevates the system's sonic ceiling well above standard wireless configurations. The KK 205's super-cardioid polar pattern provides meaningful off-axis rejection while maintaining the forward presence and transient accuracy that Neumann capsules are known for, making it equally suited to live vocal performance, broadcast interview work, and studio tracking sessions where the anchor talent mic needs to stand apart in a mix. The EM 300-500 G4 receiver adds True Diversity dual-antenna reception — an architecture that eliminates multipath dropouts by continuously comparing two independent RF paths and selecting the stronger signal before a null is ever heard.

The platform is built for multi-system professional environments. The 88 MHz bandwidth with 3,520 selectable frequencies gives the RF coordinator the channel density needed for large broadcast trucks, theatrical installations, and festival stages running 20 or more wireless systems simultaneously. The Ethernet-connected WSM software extends this coordination to remote monitoring and frequency management across a full rack of G4 units. Three-step RF power adjustment (10/30/50 mW) gives the system engineer fine control over the RF environment and transmitter battery life. The included NT 2-3 power supply, GA3 rack kit, and mic clip make it a complete, ready-to-rack professional system. The analog compander is the honest limitation of the G4 generation — it is broadcast-quality, not studio-silent, and engineers who need the lowest possible noise floor for music recording should evaluate Sennheiser's digital EW-D or EW-DX platform instead.

Frequently Asked Questions

The KK 205 is a genuine Neumann-designed super-cardioid condenser capsule — the same capsule heritage used in Neumann studio microphones, adapted for the Sennheiser G4 transmitter platform. Where standard wireless capsules are optimized for cost and handling noise, the KK 205 prioritizes transient accuracy and low-frequency body warmth. In practice, the difference is audible in upper-midrange detail and presence on close-mic vocal sources — speech intelligibility and musical resonance are both elevated compared to a generic wireless capsule.
True Diversity uses two independent receive antennas and two independent RF paths in the receiver, continuously selecting the better signal in real time. When a single-antenna receiver encounters a multipath null — a dead spot caused by RF reflections canceling — it drops signal. A True Diversity receiver switches to the second antenna before the dropout occurs. For live stage use where a performer is moving through complex RF environments, True Diversity is the difference between occasional crackle and a clean, uninterrupted signal all night.
The EM 300-500 G4 receiver supports up to 32 compatible channels operating simultaneously within its frequency range. This means a venue can run 32 independent wireless microphone systems in the same frequency band without intermodulation interference, provided channels are correctly coordinated. This is the Wireless Systems Manager (WSM) software's job — it calculates intermodulation-free frequency sets across all active G4 systems.
The SKM 500 G4 transmitter adjusts RF output power in three steps: 10 mW, 30 mW, and 50 mW. Higher power (50 mW) extends reliable range and fights RF interference but increases battery drain. Lower power (10 mW) is used in small venues or studio environments where range isn't required and you need to reduce RF density in a congested frequency environment. The adjustable power is a coordination tool for the RF engineer, not just a battery management feature.
Yes — the EM 300-500 G4 is a half-rack receiver that ships with a GA3 rack kit, allowing it to be mounted two-per-1U in a standard rack. The Ethernet connection enables Wireless Systems Manager (WSM) control, so a rack of G4 receivers can be monitored, scanned, and frequency-coordinated from a single connected computer — essential for multi-channel broadcast and theatrical setups.
