Sennheiser EW 100 G4-935-S Rugged all-in-one wireless system

Product Overview

The Sennheiser EW 100 G4-935-S is a rugged, all-in-one professional wireless handheld system engineered for singers, presenters, and live-sound professionals who demand reliability on stage. It pairs the battle-tested MMD 935-1 dynamic cardioid capsule — the same character as Sennheiser's legendary e 935 — with the compact EM 100 G4 half-rack receiver in one complete, ready-to-perform package. Built on the fourth-generation EW 100 platform, the system delivers 1,680 switchable UHF frequencies, true diversity reception, and HDX compander technology for transparent, high-fidelity wireless audio. Whether you're running a single-channel club gig or expanding to a multi-channel festival setup, the 935-S gives you a professional foundation at an accessible price point.

Product Description

At the heart of the EW 100 G4-935-S is the SKM 100 G4-S handheld transmitter — a lightweight aluminum-bodied microphone housing the MMD 935-1 dynamic cardioid capsule. The cardioid pickup pattern captures sound directly in front while rejecting off-axis noise from monitors and audience, making it an ideal all-rounder for lead vocals, speeches, and presentations. The capsule's dynamic element handles high SPLs without distortion, and the integrated mute switch lets performers silence the mic discreetly between takes or segments.

The companion EM 100 G4 receiver is a true diversity, half-rack unit in a full-metal housing. Its backlit LCD display gives you real-time visibility of RF signal strength, audio level, battery status, and frequency at a glance. Setup is fast: simply place transmitter and receiver in line-of-sight and use the infrared sync function to clone frequency data from receiver to transmitter in seconds. The system supports up to 20 compatible channels simultaneously, and the new linking function lets one receiver master push frequency assignments to up to 12 units at once — a huge time-saver for multi-channel events.

Frequency agility is a core strength of the G4 platform. With up to 42 MHz of UHF bandwidth and 1,680 selectable frequencies, you have the flexibility to find clean spectrum even in congested RF environments. RF output power reaches up to 30 mW (region-dependent), delivering a transmission range of up to 100 meters (300 feet) in typical conditions. Two AA batteries power the transmitter for up to 8 hours of continuous use. The EM 100 G4 receiver accepts both rack power and portable power options, fitting into touring racks and portable field rigs alike. The included rack kit, RJ10 linking cable, and mic clip mean you have everything needed to go live right out of the box.

Frequently Asked Questions

Q: What is included in the EW 100 G4-935-S box?

The system ships complete with the SKM 100 G4-S handheld transmitter (with MMD 935-1 capsule), the EM 100 G4 half-rack receiver, a rack-mount kit, an RJ10 linking cable, and a mic clip. Batteries and an XLR cable are not included.

Q: Which frequency band should I choose — A, A1, or G?

Band selection depends on the RF environment in your region. In the US, Band A (516–558 MHz) and A1 (470–516 MHz) are common choices; Band G (566–608 MHz) may be restricted in some markets. Check current frequency coordination guidelines or consult a local RF engineer before purchasing.

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

Up to 20 compatible channels can operate simultaneously in a single RF environment, making the 100 G4 platform suitable for mid-scale multi-channel live events.

Q: What is the difference between the 835-S, 845-S, and 935-S capsules?

All three are dynamic capsules on the same SKM 100 G4-S transmitter platform. The 835-S uses the MMD 835-1 cardioid capsule (based on the e 835) — a neutral, versatile all-rounder. The 935-S uses the MMD 935-1 cardioid capsule (based on the e 935) — a step up in presence and output, still cardioid. The 845-S uses the MMD 845-1 super-cardioid capsule (based on the e 845) — a tighter pickup pattern that rejects more off-axis sound and provides greater feedback rejection before gain, making it preferable for loud stage monitor environments. Choose the 835-S or 935-S for versatile vocal use; choose the 845-S when stage volume or feedback is a primary concern.

Q: Can I replace or swap the capsule on the SKM 100 G4-S transmitter?

Yes. The SKM 100 G4-S transmitter accepts Sennheiser's MMD capsule range, allowing you to swap between cardioid, super-cardioid, and condenser capsule modules without replacing the transmitter body.

Q: Does the EW 100 G4-935-S work with older EW 100 G3 receivers?

The G4 and G3 systems are not cross-compatible for wireless audio transmission. However, both generations use the same MMD capsule thread, so capsules are interchangeable between G3 and G4 transmitter bodies.

Q: How do I sync the transmitter frequency to the receiver?

Point the transmitter's IR window toward the receiver's IR sensor and press the sync button. The receiver clones its active frequency to the transmitter in seconds. No manual frequency entry is required.

Q: Is the EM 100 G4 receiver suitable for camera mounting?

The EM 100 G4 is a half-rack receiver designed for rackmount or tabletop use. For camera-mount applications, Sennheiser offers the EK 100 G4 camera receiver as a companion unit. The EM 100 G4 in this set is optimized for FOH rack or stage-box installations.
