Sennheiser EW-D ME4 SET (Q1-6) Digital Wireless Cardioid Lavalier Microphone System (Q1-6: 470 to 526 MHz)

The Sennheiser EW-D ME4 SET is a complete digital wireless system integrating a cardioid lavalier microphone with a bodypack transmitter and a portable receiver, engineered for professional vocal capture in presentations, broadcast, theater, and live event applications. Operating within the Q1-6 frequency range of 470 to 526 MHz, this system leverages 24-bit/48 kHz digital wireless transmission to deliver pristine, uncompressed audio quality with exceptional dynamic range and negligible latency. The core of the system is the ME4 miniature cardioid condenser microphone capsule, renowned for its intelligibility and ability to minimize background noise, making it ideal for spoken word in challenging acoustic environments. The microphone connects to the slim, ergonomic bodypack transmitter, which is designed for discreet and secure concealment under clothing, providing presenters, performers, and speakers with complete freedom of movement without compromising audio integrity.

The system's portable receiver offers remarkable flexibility, capable of operating as a stand-alone desktop unit or integrating seamlessly into larger setups via its comprehensive output options. It features a clear OLED display that provides real-time monitoring of audio levels, RF signal strength, and battery status for both the receiver and the paired transmitter. A significant advancement in this digital generation is the inclusion of an integrated Ethernet port, enabling direct connectivity to Sennheiser's Wireless Systems Manager software for advanced frequency coordination, remote control, and monitoring of multiple systems—a critical feature for broadcast engineers and large-scale event production. The receiver's robust metal construction and intuitive interface make it equally suitable for fixed installations, rental inventories, and mobile production kits.

Designed with the user in mind, the EW-D system incorporates several intelligent features that simplify operation and enhance reliability. The transmitter and receiver feature automatic frequency synchronization, allowing for quick, error-free setup. The system employs advanced encryption for secure transmission, preventing unauthorized interception—a paramount requirement for corporate and government use. With a robust operating range, long battery life from standard AA batteries, and professional-grade components throughout, the Sennheiser EW-D ME4 SET provides a reliable, high-performance wireless solution that combines broadcast-quality audio with the operational simplicity and future-proof networking capabilities demanded by today's audio professionals.
