Sennheiser EW-D ME2 Wireless Lavalier Microphone System (R4-9: 552-607MHz)

The Sennheiser EW-D ME2 SET with ME 2 Omnidirectional Lavalier delivers high-quality 24-bit digital audio with an impressive 134 dB dynamic range, a precise equidistant tuning grid, and Bluetooth setup via a smartphone app, creating a professional wireless microphone system that is simple to use. Designed for both first-time and experienced users, it meets the needs of presenters, lecturers, clergy, and live performers alike, providing reliable performance in business, educational, worship, or stage environments.

Its ultrawide dynamic range eliminates the need for input-sensitivity adjustments on the transmitter, while the equidistant tuning grid, based on Sennheiser’s Digital 6000/9000 systems, allows operation of up to 90 channels simultaneously without frequency conflicts. The UHF transmission extends the range up to 330 feet, and the 56 MHz bandwidth ensures access to clean frequencies across 2240 options. Intelligent Switching Diversity minimizes RF interference, and the system’s ultralow 1.9 ms latency ensures live performance audio is immediate. Bluetooth connectivity allows seamless pairing and remote control via the Smart Assist App, automatically managing mic levels and securing reliable signals within seconds.

The set includes a single-channel EW-D EM receiver, the unobtrusive ME 2 omnidirectional lavalier mic optimized for speech clarity, and the lightweight, rugged EW-D SK bodypack transmitter. The transmitter pairs with the receiver via Bluetooth Low Energy from up to 120 feet, and provides up to eight hours of operation on AA batteries or up to twelve hours with a separately available BA 70 lithium-ion pack. The half-rack EW-D EM receiver features a durable all-metal chassis, removable antennas, a high-contrast OLED display, and intuitive front-panel controls. It offers balanced XLR and unbalanced 1/4" outputs for direct connection to any PA system or mixer, with auto-scan functionality to locate the cleanest available frequency.

The system’s equidistant tuning grid maximizes channel capacity while preventing intermodulation issues in congested RF environments. Intelligent Switching Diversity monitors two antennas and circuits to maintain optimal audio quality, and the UHF operation avoids interference from 2.4 GHz Wi-Fi networks. Using the Smart Assist App, users can pair and control up to sixteen channels from a single mobile device, access automatic or manual frequency allocation, monitor battery status, mute channels, and organize systems without prior wireless expertise.

Additional options enhance reliability, including longer detachable antennas, front-mount kits, directional remote antennas, and active antenna splitters for multi-receiver setups. The EW-D system is compatible with a variety of Sennheiser microphones, including subminiature MKE 2 omnidirectional lavaliers, ME 4 and ME 3 cardioid lavaliers and headsets, handheld SKM-S transmitters with multiple mic capsules, and CI 1 instrument cables for guitars, keyboards, or bass. The system’s versatility, durability, and professional-level performance make it ideal for anyone requiring a dependable wireless microphone setup.
