Product Overview

The Sennheiser EW 112P G4 is a complete portable wireless lavalier microphone system built for run-and-gun video production, electronic news gathering (ENG), and documentary filmmaking. It pairs the ME 2-II omnidirectional lavalier microphone with the SK 100 G4 bodypack transmitter and the compact EK 100 G4 camera-mount receiver in a single, ready-to-use kit. Operating in the A Band (516–558 MHz), this system delivers broadcast-quality audio with the field-proven reliability that Sennheiser's Evolution Wireless G4 platform is known for. At $649, it offers professional-grade wireless performance at a price point accessible to independent videographers and production teams alike.

Product Description

Designed from the ground up for mobility, the EW 112P G4 puts professional wireless audio within reach of any video crew. The ME 2-II lavalier microphone features an omnidirectional polar pattern optimized for natural speech reproduction, and its discreet clip-on design keeps it virtually invisible on camera. The SK 100 G4 bodypack transmitter is compact and lightweight, making it comfortable for talent to wear throughout long shoots. The EK 100 G4 receiver mounts directly to a camera's cold shoe or hot shoe via the included CA 2 adapter, eliminating the need for external mounting hardware. With up to 1,680 tunable frequencies across a 42 MHz switching bandwidth, finding a clean channel is fast and reliable in congested RF environments. The automatic frequency scan identifies open frequencies instantly, and wireless infrared sync pushes settings from the receiver to the transmitter without menus. A 330-foot (100 m) operating range gives talent freedom of movement, while up to 8 hours of battery life covers a full day of field production. The system supports linking up to 12 compatible receivers for multi-channel simultaneous setups. HDX compander technology ensures crystal-clear audio with minimal noise, and the pilot tone squelch eliminates unwanted RF noise when the transmitter is powered off. The EW 112P G4 is fully backward-compatible with Evolution G1, G2, and G3 systems, protecting your existing accessory investment. Included cables — CL 1 jack and CL 100 XLR — connect the receiver to any camera audio input.
