Sennheiser EW 100 G4-835-S-G Rugged all-in-one wireless system

Product Overview

The Sennheiser EW 100 G4-835-S-G is a versatile, all-in-one professional wireless handheld system built around the MMD 835-1 dynamic cardioid capsule — the wireless expression of Sennheiser's industry-standard e 835 microphone. Designed for singers, speakers, and presenters who need a natural, balanced vocal character across a wide range of live and AV applications, the 835-S pairs seamlessly with the EM 100 G4 half-rack receiver in the complete G-band (566–608 MHz) kit. Fourth-generation EW 100 platform features — including 1,680 switchable UHF frequencies, true diversity reception, and HDX compander technology — deliver the wireless reliability and audio transparency that professionals have come to expect from the EW 100 series. At $749, the EW 100 G4-835-S-G is an outstanding entry point into fully professional wireless vocal performance.

Product Description

The MMD 835-1 cardioid capsule in the SKM 100 G4-S transmitter is the defining character of this system. Based on Sennheiser's legendary e 835 — one of the most widely used dynamic vocal microphones in live sound — it offers a natural, slightly presence-lifted frequency response that flatters a broad range of voices without excessive coloration. The cardioid pattern captures sound in a wide front arc, making it forgiving of movement and mic technique while still providing meaningful rejection of rear-sourced noise. For house-of-worship pastors, corporate presenters, versatile vocalists, and event emcees who move between speaking and singing, the 835-S capsule is a reliable, neutral choice.

The lightweight aluminum SKM 100 G4-S transmitter body fits comfortably in the hand and includes an integrated mute switch for discreet on-stage silencing. The MMD 835-1 capsule module threads securely onto the transmitter and can be swapped for other MMD capsule options in the field, giving you flexibility to reconfigure the system as application needs change.

The EM 100 G4 true diversity half-rack receiver anchors the system at the mix position or in a touring rack. Its full-metal housing, backlit LCD display, and front-panel controls give engineers complete command of RF scanning, audio level, squelch, and display modes. Infrared frequency sync makes transmitter setup fast and reliable, and the RJ10 linking port lets a single receiver push its frequency settings to up to 12 additional units simultaneously — a powerful feature for multi-channel event builds. G-band operation (566–608 MHz) with 42 MHz of tunable bandwidth and 1,680 selectable frequencies ensures you can find clean spectrum in dense RF environments, supporting up to 20 compatible simultaneous channels.

Frequently Asked Questions

Q: How does the 835-S compare to the 845-S and 935-S — which should I choose?

All three share the same SKM 100 G4-S transmitter platform and EM 100 G4 receiver, differing only in the capsule. The 835-S (MMD 835-1) is a dynamic cardioid based on the e 835 — a neutral, versatile all-rounder ideal for varied vocal styles and mixed speaking/singing use. The 935-S (MMD 935-1) is also a dynamic cardioid but based on the higher-output e 935, offering a bit more presence and projection — a step up for more demanding lead-vocal applications. The 845-S (MMD 845-1) is a dynamic super-cardioid based on the e 845, with a tighter polar pattern that rejects more off-axis sound and provides greater gain-before-feedback — best for loud stage environments with significant monitor bleed. If you're unsure, the 835-S is the safest starting point for versatile, all-purpose use.

Q: Is the G-band (566–608 MHz) available for use in my region?

G-band availability varies by country and region. In the United States, portions of the 566–608 MHz spectrum may be subject to FCC licensing or coordination requirements. Always verify local spectrum regulations before purchasing a frequency-specific wireless system.

Q: How many EW 100 G4 systems can I run simultaneously?

Up to 20 compatible EW 100 G4 channels can operate in the same RF environment simultaneously without mutual interference, making this platform suitable for mid-to-large multi-channel live events.

Q: Can the SKM 100 G4-S transmitter use rechargeable batteries?

Yes. The transmitter accepts standard AA NiMH rechargeable batteries in addition to alkaline AAs. Battery runtime up to 8 hours is based on standard alkaline batteries; NiMH runtime may vary slightly depending on battery capacity.

Q: Can I replace the MMD 835-1 capsule with a different Sennheiser capsule?

Yes. The SKM 100 G4-S transmitter is designed for capsule swapping across the MMD range. You can replace the 835-1 with other MMD cardioid, super-cardioid, or condenser capsules to repurpose the system for different applications.

Q: What is the difference between the EM 100 G4 and the EK 100 G4 receiver?

The EM 100 G4 included in this system is a half-rack rackmount receiver intended for FOH or installed audio rack use. The EK 100 G4 is a compact bodypack-style camera receiver designed for mounting on a camera hot shoe or boom. This product ships with the EM 100 G4 rackmount unit.

Q: Does infrared sync work in all lighting conditions?

Infrared sync works best in typical indoor lighting. Strong direct sunlight or bright stage lighting aimed directly at the IR windows can interfere with the sync process. In those cases, simply shade the IR windows briefly during the sync operation for a reliable connection.

Q: Is the EW 100 G4-835-S-G a good choice for a rental inventory?

Yes. The rugged all-metal construction, simple operating concept, swappable capsule system, fast IR sync, and broad application range make the EW 100 G4-835-S-G an excellent workhorse for event rental companies. Up to 20 simultaneous channels and the multi-unit linking function further simplify large event deployments.
