The Sennheiser EW-D ME4 SET (Q1-6) is a professional, fully digital wireless lavalier system designed for discreet, high-fidelity speech capture in broadcast, corporate, theater, and live production. Operating within the 470 to 526 MHz UHF frequency band, this system provides stable, interference-resistant RF performance suitable for complex spectral environments. The set includes a digital bodypack transmitter paired with the Sennheiser ME 4 omnidirectional miniature condenser lavalier microphone and a compatible true-diversity receiver, offering a complete, optimized solution for presenters, actors, and interviewees where clear, natural dialogue and concealment are paramount.

The system's key component is the ME 4 lavalier microphone, a successor to the renowned ME 2, known for its neutral, transparent sound quality and excellent speech intelligibility. Its miniature size and omnidirectional polar pattern ensure consistent audio capture even when the subject turns their head, making it ideal for dynamic presentations and interviews. The microphone connects via a secure, locking mini-jack to the digital bodypack transmitter, which is built with a durable metal housing. The transmitter converts the analog microphone signal to digital immediately, creating a clean, secure digital data stream for wireless transmission that is immune to the RF intermodulation issues common in analog systems.

The accompanying digital receiver features a clear color LCD display for comprehensive monitoring of system status, RF signal strength, audio levels, and transmitter battery life. It incorporates advanced professional features including automatic frequency management that scans and selects the optimal channel, 128-bit AES encryption for secure transmission, and Ethernet connectivity for networking multiple systems and enabling remote control via software. The digital transmission ensures audio quality with extremely low latency and a wide dynamic range. The receiver provides both balanced XLR and unbalanced 6.3 mm jack outputs for direct connection to mixing consoles, camera inputs, or recorders. As a complete set, the EW-D ME4 (Q1-6) offers a future-proof, reliable digital wireless lavalier solution that meets the highest standards for audio quality, operational security, and ease of use in professional applications.
