Sennheiser EW 112P G4 Overview

The Sennheiser EW 112P G4 camera-mount wireless lavalier microphone system is a reliable and flexible choice for videographers, journalists and content creators. This system provides broadcast-quality sound and has become an industry standard all over the world.

The EW 112P G4 gives you the tools to adapt and meet the wireless challenges that inevitably arise on set. The frequency scan function automatically searches for the cleanest frequency at your location, while the adjustable input sensitivity on the transmitter accommodates mic levels ranging from booming voices to quiet speech, and even line-level audio.

The system includes the improved ME 2-II omnidirectional lavalier mic, a bodypack transmitter, and a camera-mount receiver. It connects to a camcorder or a DSLR/mirrorless camera to capture crisp-sounding speech or dialogue for projects ranging from documentaries to wedding videos, corporate spots, and hands-free interviews.

The EW 112P G4 is backward-compatible with previous evolution systems, giving you the ability to mix and match G4/G3/G2/G1 receivers or bodypack, handheld, and plug-on transmitters. It is also compatible with EW 500 systems.

Built for Dependable Performance in the Field

  • The EW 112P G4 features rugged, all-metal chassis well suited for extended use on location. The lightweight, compact bodypack transmitter is easy to conceal and offers rounded edges that are soft to the touch and comfortable for the talent to wear. A locking connector ensures that your lav doesn't detach at a critical moment, while a convenient switch allows you to mute your mic.
  • Using the included shoe mount adapter, the equally compact receiver easily mounts your camera without adding much weight. The included cables allow you to connect the receiver to the 3.5mm or XLR audio input of any DSLR/mirrorless, camcorder, or recording device.
  • Both transmitter and receiver feature daylight-readable LED displays showing reception quality, battery status, and audio level. To get you going quickly, they synchronize via an infrared interface with the simple push of a button.

Proven Broadcast-Quality Sound

  • The EW 112P G4 ships with the popular ME 2-II omnidirectional lavalier microphone, which delivers a natural sound optimized for speech intelligibility. Its omnidirectional polar pattern ensures that the sound remains consistent, even when the speaker's head moves away from the mic.
  • To take full advantage of the ME 2-II's dynamic range, the system employs proprietary HDX compander technology, preserving your sound without adding unwanted noise during transmission, and delivering audio with remarkable accuracy and quality.

Additional Features

  • Operate up to 12 wireless mics at once on set
  • Unlike digital wireless systems, the SK 100 G4 transmitter can transmit to an unlimited number of EW Series receivers
  • A wide range of accessories adapts the system to a variety of applications
