Sennheiser EW 100 G4-ME2 Wireless Bodypack

Product Overview

The Sennheiser EW 100 G4-ME2 is a professional Evolution Wireless G4 camera-mount lavalier microphone system designed for ENG, broadcast reporting, and corporate video production. The system bundles the SK 100 G4 bodypack transmitter, the ME 2 omnidirectional lavalier microphone, and the EM 100 G4 compact camera-mount receiver into a complete, field-ready package. Available in three frequency variants—A (516–558 MHz), A1 (470–516 MHz), and G (566–608 MHz)—the EW 100 G4 provides 100 selectable frequencies per band and UHF transmission with up to 100 meters of operating range. The HDX compander and analogue audio output via 3.5 mm jack make this system compatible with a wide range of cameras, field recorders, and mixing consoles.

Product Description

The EW 100 G4 series occupies the professional entry tier of Sennheiser's Evolution Wireless G4 platform, offering proven UHF analogue wireless performance in a compact, camera-optimized form factor. The EM 100 G4 camera-mount receiver is specifically sized for attachment to DSLR, mirrorless, and ENG cameras, with a standard shoe mount and a 3.5 mm unbalanced output that feeds directly into camera mic inputs. For broadcast and field recording scenarios requiring balanced audio, an optional XLR adapter connects the receiver to professional audio gear. The SK 100 G4 bodypack transmitter features a backlit display and keypad lock, allowing presenters and field reporters to operate the transmitter without accidentally changing settings during recording. The ME 2 omnidirectional lavalier capsule provides consistent sensitivity across a wide pickup angle, making it tolerant of head movement and suitable for talkers who are not accustomed to precise mic placement discipline. The HDX compander—Sennheiser's proprietary analogue noise reduction and dynamic range optimization circuit—minimizes analogue noise floor while maintaining natural audio character, delivering clean results into camera inputs that lack sophisticated preamps. Each frequency band offers 100 selectable frequencies with 25 kHz channel spacing, and the infrared sync system allows quick transmitter-to-receiver frequency matching without manually scrolling through channel banks. The EW 100 G4-ME2 is compatible with the Sennheiser Wireless Systems Manager (WSM) software for multi-channel frequency coordination, making it practical for multi-camera productions and conference setups running several simultaneous systems. The system is available in band A (516–558 MHz), band A1 (470–516 MHz), and band G (566–608 MHz); frequency availability varies by country, so customers should verify spectrum compliance for their region before purchasing.

Key Features

• ENG-Optimized Camera-Mount Receiver — EM 100 G4 compact receiver mounts directly on camera shoe; 3.5 mm output feeds camera mic input without additional equipment.
• ME 2 Omnidirectional Lavalier — Natural, full-range omni pickup tolerates movement; consistent sensitivity regardless of capsule orientation.
• SK 100 G4 Bodypack Transmitter — Backlit display, keypad lock, and 3.5 mm locking input for ME 2 and compatible Sennheiser lavalier microphones.
• HDX Compander — Sennheiser's proprietary high-dynamic analogue processing minimizes noise floor and preserves audio quality through the analogue RF chain.
• 100 Selectable Frequencies per Band — Manual or auto-scan frequency selection provides flexibility in occupied RF environments.
• Infrared Sync — Fast transmitter-to-receiver frequency matching via IR port; point and sync without navigating menus.
• Three Frequency Band Options — Available in band A (516–558 MHz), A1 (470–516 MHz), and G (566–608 MHz) to suit regional spectrum availability.
• 100-Meter Operating Range — Up to 100 m / 300 ft line-of-sight UHF range covers outdoor ENG, stage, and large venue applications.
• WSM Software Compatible — Integrates with Sennheiser Wireless Systems Manager for multi-channel frequency coordination in complex productions.
• True Diversity Reception — Dual-antenna diversity on the EM 100 G4 receiver reduces dropouts in multipath RF environments.

Frequently Asked Questions

Q: Which frequency band should I choose for the EW 100 G4-ME2?

Band selection depends on the UHF spectrum available in your country. Band A1 (470–516 MHz) and Band A (516–558 MHz) are common choices for North America and much of Europe. Band G (566–608 MHz) may face restrictions in regions where that spectrum has been reallocated to cellular or broadcast services. Verify local spectrum regulations before purchasing.

Q: Does the EM 100 G4 receiver connect directly to a DSLR or mirrorless camera?

Yes. The EM 100 G4 camera-mount receiver attaches to a standard hot shoe and outputs audio via a 3.5 mm TRS jack that connects to the camera's mic input. No mixer or additional preamp is required for typical camera-to-receiver signal flow.

Q: What is the HDX compander and why does it matter?

HDX is Sennheiser's high-dynamic compander circuit used in analogue wireless systems. It encodes the audio signal at the transmitter and decodes it at the receiver to achieve a lower noise floor and wider dynamic range than standard analogue transmission. It is designed to be transparent to the listener while improving signal-to-noise performance.

Q: How does the infrared sync work?

Point the front of the SK 100 G4 bodypack transmitter at the IR port on the EM 100 G4 receiver and activate the sync function on the receiver. The receiver transmits its current frequency to the bodypack via IR, instantly matching transmitter and receiver channels without manual frequency entry.

Q: Can I run multiple EW 100 G4 systems simultaneously?

Yes. Each frequency band offers 100 selectable frequencies. In practice, the number of interference-free simultaneous channels depends on local RF conditions. Sennheiser's free Wireless Systems Manager (WSM) software assists with multi-channel coordination to maximize compatible frequency sets.

Q: Is the ME 2 lavalier interchangeable with other microphones on the SK 100 G4 bodypack?

Yes. The SK 100 G4 accepts any Sennheiser Evolution Wireless compatible microphone with a 3.5 mm locking jack connector, including other lavalier models and headset microphones from the Evolution Wireless accessory lineup.

Q: How does the EW 100 G4-ME2 differ from the EW-D ME2 SET?

The EW 100 G4-ME2 uses analogue UHF transmission with the HDX compander and includes a camera-mount receiver, making it purpose-built for ENG and field video work. The EW-D ME2 SET uses fully digital UHF transmission with 24-bit audio, 134 dB dynamic range, Bluetooth setup, and a rackmount/tabletop receiver, making it better suited for fixed installations, theater, and high-density channel deployments.

Q: What batteries does the SK 100 G4 bodypack use?

The SK 100 G4 runs on a single AA battery. Battery life varies by battery type and transmit power setting; Sennheiser recommends alkaline or rechargeable NiMH AA cells. The EM 100 G4 camera receiver is powered by AA batteries or via a DC power input depending on the configuration.
