Clear and Detailed Audio with 24-Bit Digital Performance

At the core of the EW-D ME 4 is Sennheiser’s renowned 24-bit digital audio engine, offering studio-quality sound with exceptional clarity. The system boasts a wide 20 Hz to 20 kHz frequency response and a 134 dB dynamic range, capturing everything from soft speech to powerful vocals without distortion or manual gain adjustment.

With ultralow latency of just 1.9 ms, the system ensures real-time audio transmission, perfect for live performances and speaking engagements.

Reliable UHF Wireless Technology with Simplified Frequency Coordination

Operating in the UHF band, the EW-D avoids interference from common Wi-Fi networks, ensuring a stable connection in even the most congested environments. The 56 MHz bandwidth provides access to 2240 frequencies, while the equidistant tuning grid, borrowed from Sennheiser’s higher-end systems, eliminates intermodulation issues and allows you to run up to 90 wireless channels simultaneously.

With Intelligent Switching Diversity, the receiver constantly compares signals from two antennas and automatically switches to the strongest one without interrupting the audio, ensuring maximum stability and clarity.

ME 4 Cardioid Lavalier Microphone and Durable Bodypack Transmitter

Included in the set is the ME 4 cardioid lavalier mic, designed to isolate your voice in noisy environments. Its directional polar pattern makes it ideal for use in crowded spaces like trade shows, sports arenas, or auditoriums.

The mic connects to the EW-D SK bodypack transmitter, built with a rugged metal housing for daily use. The transmitter includes:

• A lockable mute button with remote override

• Bluetooth Low Energy pairing from up to 120 feet away

• Up to 8 hours of battery life on AA batteries or 12 hours with the BA 70 rechargeable battery (sold separately)

Half-Rack Receiver with OLED Display and Easy Controls

The app also includes video tutorials and a support hub to help new users get started. If your phone isn't available, all functions remain accessible directly on the receiver.

Scalable Wireless for Complex Setups
