Sennheiser EW 100 G4-ME3 Rugged all-in-one wireless system for presenters and singers

Product Overview

The Sennheiser EW 100 G4-ME3 is a complete all-in-one wireless system combining the ME 3-II cardioid headset microphone, SK 100 G4 bodypack transmitter, and EM 100 G4 compact receiver in a single package optimized for presenters, vocalists, and educators. Operating in the UHF band with up to 42 MHz tuning bandwidth and 1,680 selectable frequencies, the system delivers stable, interference-resistant RF performance in crowded spectrum environments. The EM 100 G4 receiver's compact form factor fits directly on a camera hot shoe or can be rack-mounted for fixed installations, while the full-metal housing ensures durability in daily use. HDX compander technology and up to 100 meters of transmission range make this an industry-standard choice for conference rooms, houses of worship, fitness studios, and live performance venues.

Product Description

The EW 100 G4-ME3 sits in Sennheiser's Evolution Wireless G4 100-series, the entry point into professional wireless audio with the reliability and feature set that demanding users require. The ME 3-II headset microphone is engineered for speech intelligibility, with a cardioid polar pattern that rejects off-axis noise and a sweat-resistant cable and capsule housing suited to vigorous activity. Infrared transmitter-to-receiver sync eliminates manual frequency entry — simply point the transmitter at the receiver and synchronize in seconds. The system supports up to 12 receivers linked for fast simultaneous frequency allocation, which is critical for larger events where multiple wireless channels must be coordinated quickly. Sennheiser's HDX compander provides clean audio with low noise and distortion across the signal chain. RF output power reaches up to 30 mW (country dependent), and the true diversity receiver design minimizes dropouts by continuously selecting the stronger of two antenna signals. The SK 100 G4 bodypack runs up to 8 hours on AA batteries, covering full-day conference and event schedules without mid-session battery changes. The EM 100 G4 receiver's intuitive LCD display provides real-time RF and audio level monitoring at a glance. Available in multiple frequency bands (A, A1, G) to comply with regional spectrum regulations.

Frequently Asked Questions

Q: What microphone is included in the EW 100 G4-ME3?

The system includes the ME 3-II cardioid headset microphone, which is designed for high speech intelligibility with sweat-resistant construction for daily stage and presentation use.

Q: What frequency band should I select for use in the United States?

For US operation, band A (516–558 MHz, SKU 509645) or band A1 (470–516 MHz, SKU 509644) are the primary UHF options. Always verify current FCC frequency availability in your region before purchasing, as spectrum allocations can change.

Q: How many simultaneous wireless systems can I run with the EW 100 G4?

Up to 20 compatible channels can operate simultaneously within a single frequency band, and the G4 linking feature supports fast frequency coordination across up to 12 receivers.

Q: Can the EM 100 G4 receiver be rack-mounted?

Yes. The EM 100 G4 is a half-rack receiver that can be rack-mounted with optional rack-mount hardware. It also fits directly on a camera hot shoe for mobile or ENG applications.

Q: How long do batteries last in the SK 100 G4 bodypack?

The SK 100 G4 provides up to 8 hours of operation on standard AA batteries, sufficient for most full-day events and conference schedules.

Q: Is the ME 3-II headset suitable for high-perspiration environments?

Yes. The ME 3-II headset is constructed to be sweat-resistant, making it appropriate for fitness instructors, active performers, and presenters in warm environments.

Q: Does the EW 100 G4 support Sennheiser Wireless Systems Manager software?

The EW 100 G4 series supports basic synchronization and frequency management. For advanced network-based monitoring and control, Sennheiser's higher-tier systems such as the EW-D or Digital 6000 series offer broader WSM integration.

Q: How does the infrared sync work?

The transmitter and receiver have built-in IR transceivers. After selecting a frequency on the receiver, hold the transmitter's IR port close to the receiver's IR port and initiate sync — the frequency and settings transfer automatically without manual entry.
