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

The Sennheiser EW-D ME4 SET with ME 4 Cardioid Lavalier delivers pristine 24-bit digital audio with a 134 dB dynamic range, an equidistant tuning grid, and convenient Bluetooth setup through a smartphone app, creating a professional wireless microphone system designed for ease of use. Straightforward to set up and operate, it offers advanced features that meet the demands of both newcomers and professionals, making it an excellent solution for presenters, educators, clergy, and live performers working in venues ranging from classrooms and houses of worship to theaters and concert stages.

The wide dynamic range eliminates the need for sensitivity adjustments on the transmitter, while the equidistant tuning grid allows operation of up to 90 simultaneous channels without frequency conflicts. UHF transmission extends range up to 330 feet, and a 56 MHz bandwidth provides access to 2240 selectable frequencies. Intelligent Switching Diversity minimizes RF interference, and an ultralow latency of 1.9 ms ensures real-time performance accuracy. Bluetooth connectivity makes pairing simple and enables full control through the Smart Assist App, which automatically adjusts mic levels and secures a reliable connection in seconds.

This configuration includes a single-channel EW-D EM receiver, the directional ME 4 cardioid lavalier mic designed to capture speech with clarity while rejecting background noise, and the rugged yet lightweight EW-D SK bodypack transmitter built with a durable metal housing. The transmitter pairs with the receiver via Bluetooth Low Energy from up to 120 feet and offers up to eight hours of operation with AA batteries or twelve hours with a BA 70 lithium-ion pack available separately. The receiver, housed in a robust half-rack all-metal chassis, can be tabletop or rackmounted and features detachable antennas, intuitive front-panel controls, and a high-contrast OLED screen for quick navigation even in low-light settings.

The system provides balanced XLR and unbalanced 1/4-inch outputs for flexible connections to mixers and PA systems, while its auto-scan feature locates the cleanest frequency automatically. With equidistant spacing across the bandwidth, the EW-D prevents intermodulation issues and maintains solid reliability even in crowded RF environments. Intelligent Switching Diversity continuously monitors signals across two antennas to ensure optimal wireless quality, while UHF operation keeps it free from 2.4 GHz Wi-Fi interference. The Smart Assist App adds streamlined setup and centralized control for up to sixteen channels per mobile device, with the ability to manage additional channels from more devices.

For greater reliability, the system supports antenna upgrades, front-mount kits for rack installations, directional antennas for stronger coverage, and active antenna splitters for larger multi-receiver configurations. Compatible with a variety of Sennheiser microphones and accessories, the system can be expanded with options such as the discreet MKE 2 lavalier, the ME 2 omnidirectional lavalier, the ME 3 cardioid headset, handheld SKM-S transmitters with interchangeable capsules, or instrument cables for guitars and keyboards. With its adaptability, professional performance, and rugged build, the EW-D ME4 SET is a dependable choice for any application requiring a reliable wireless microphone system.
