Description

Sennheiser EW-D ME4 SET (S4-7) – Digital Lavalier Wireless System for Speech, Lectures, and Moderating

The Sennheiser EW-D ME4 SET (S4-7) is a versatile, digital UHF wireless system designed specifically for speech transmission in professional applications such as conferences, educational institutions, live presentations, and moderation. It combines ease of use with modern technology and delivers clear, interference-free audio transmission—ideal for anyone who requires maximum speech intelligibility and reliable performance.

Equipped with the proven ME 4 lavalier microphone with a cardioid polar pattern, a rugged pocket transmitter in a metal housing, and a digital receiver, this set is ready for immediate use. It operates in the UHF frequency range of 630–662 MHz (S4–7), which ensures high transmission reliability and range.

Optimized for speech in challenging environments

The ME 4 cardioid lavalier microphone provides focused speech pickup while suppressing ambient noise from the sides—ideal for noisy rooms, stages, or presentations in acoustically challenging environments. With a sensitivity of 40 mV/Pa and a maximum sound pressure level of 120 dB SPL, it ensures excellent intelligibility—even with dynamic speech patterns.

Digital UHF technology for clear transmission

Digital signal processing delivers crystal-clear sound without noise, interference, or static. With a latency of just 1.9 ms, the system is ideal for live events, presentations, or hybrid formats with video transmission.

Thanks to UHF transmission, the EW-D ME4 SET offers greater range and more reliable transmission than many 2.4-GHz systems. The 56 MHz switching bandwidth allows for the simultaneous operation of up to 90 channels —perfect for multi-channel installations and larger venues.

Intelligent Setup & Convenient Control

The EW-D Smart Assist app offers an intuitive user interface for quick setup and management of the system via Bluetooth®. The automated frequency search takes the technical work off your hands and ensures the system is ready for use immediately—ideal for presenters without technical expertise.

Long-Lasting Battery Solution for Maximum Runtime

With the included BA 70 Li-ion battery pack, the system achieves an operating time of up to 12 hours. Alternatively, the transmitter can also be powered by AA batteries (up to 8 hours of runtime). This makes the system flexible and ready for use at all-day events.
