Sennheiser EW 100 G4-ME4 Wireless Cardioid Lavalier Microphone System

Product Overview

The Sennheiser EW 100 G4-ME4 is a professional UHF wireless lavalier microphone system built for presenters, broadcasters, educators, and performers who demand reliable, hands-free audio. Centered on the cardioid ME 4 clip-on microphone, the SK 100 G4 bodypack transmitter, and the camera-mountable EM 100 G4 receiver, this all-in-one system delivers broadcast-grade clarity with straightforward wireless setup. With 1,680 selectable UHF frequencies across up to 42 MHz of tuning bandwidth, it operates cleanly in congested RF environments and scales to multi-system deployments with ease. Whether you're on a conference stage, in a house of worship, or recording training content in the field, the EW 100 G4-ME4 provides the dependability that professionals rely on.

Product Description

The EW 100 G4-ME4 builds on Sennheiser's industry-proven Evolution Wireless G4 platform — a system trusted by audio professionals worldwide for its stability, ease of use, and exceptional sound quality. At the heart of the kit is the ME 4 cardioid lavalier microphone, whose directional pickup pattern actively rejects off-axis noise and feedback, making it the superior choice over omnidirectional clip-ons in challenging acoustic environments like lecture halls, houses of worship, and live event stages. The SK 100 G4 bodypack transmitter is compact and rugged, with an ergonomic form factor that disappears under clothing. Infrared sync between the bodypack and receiver makes channel coordination fast and eliminates manual frequency entry. The EM 100 G4 receiver is designed specifically for camera mounting, fitting standard 3/8" and 5/8" threads, making it ideal for ENG videographers and broadcast crews. Sennheiser's HDX compander system ensures a clean, wide dynamic range with minimal noise floor artifacts. Up to 12 systems can be linked and coordinated simultaneously using the G4 linking function, and RF output power of up to 30 mW (country-dependent) delivers transmission range up to 100 meters. The system operates across three available frequency bands (A: 516–558 MHz, A1: 470–516 MHz, G: 566–608 MHz) to match your regional spectrum. Setup and monitoring are managed via an intuitive backlit LCD on both the transmitter and receiver, giving real-time visibility into RF signal strength, battery life, and audio level. The EW 100 G4-ME4 ships ready to use — a complete professional wireless solution in a single box.

Frequently Asked Questions

Q: What is the difference between the ME 4 and ME 2-II lavalier microphones?

The ME 4 is a cardioid (directional) microphone that picks up sound primarily from the front and rejects noise from the sides and rear, making it ideal when feedback rejection and ambient noise suppression are priorities. The ME 2-II is omnidirectional, capturing sound equally from all directions — better suited for quiet studio environments where natural sound pickup is preferred.

Q: Can I use the EM 100 G4 receiver with a mixing console instead of a camera?

Yes. The EM 100 G4 receiver includes both a 3.5 mm stereo output and a 6.3 mm (1/4") output, making it compatible with cameras, mixers, audio interfaces, and PA systems. Its camera-mount design is optimized for portability, but it functions equally well on a desk or in a rack setup.

Q: How many EW 100 G4 systems can I run simultaneously in the same venue?

Up to 12 EW 100 G4 systems can be linked and frequency-coordinated simultaneously using the G4 linking function, which automates channel assignment across all linked units. With careful manual frequency planning, even more systems may be possible depending on your RF environment.

Q: What frequency band should I choose?

Band selection depends on your geographic location and local spectrum regulations. In the US, Band A (516–558 MHz) and Band A1 (470–516 MHz) are common choices, while Band G (566–608 MHz) suits other markets. Check your local frequency allocation before purchasing to ensure legal operation.

Q: Is the EW 100 G4-ME4 suitable for outdoor use?

Yes. The SK 100 G4 bodypack and EM 100 G4 receiver are built with robust housings suited for field and outdoor environments. The RF output of up to 30 mW and transmission range of up to 100 meters make it practical for outdoor events, field interviews, and on-location productions.

Q: Does this system work with other Sennheiser G4 microphone capsules?

Yes. The SK 100 G4 bodypack features a standard 3.5 mm locking jack input compatible with all Sennheiser Evolution G4 clip-on and headset microphones, including the ME 2-II (omni lavalier), ME 4 (cardioid lavalier), and various headset options.

Q: What battery type does the SK 100 G4 transmitter use?

The SK 100 G4 operates on two standard AA batteries. Battery life and type vary based on usage, but the transmitter displays real-time battery status on its LCD for monitoring.
