Sennheiser EW 112P G4 Wireless Omni Lavalier Microphone System for Camera Mounting (566 to 608 MHz, G Band)

Sennheiser EW 112P G4 Wireless Lavalier Microphone System Overview

The Sennheiser EW 112P G4 is a camera-mount wireless lavalier microphone system trusted by videographers, journalists, and content creators around the world. With its proven combination of broadcast-quality sound, reliability, and flexible controls, it’s an ideal choice for capturing dialogue on location with professional clarity.

Whether you're filming documentaries, weddings, interviews, or corporate content, this wireless system gives you the tools to adapt quickly to changing environments while delivering crystal-clear audio directly to your camera.

Reliable Wireless Audio for Video Production

This system includes everything needed for two-point wireless audio recording: the ME 2-II omnidirectional lavalier microphone, a compact bodypack transmitter, and a camera-mount receiver. Both units are made from durable, all-metal chassis built to withstand the rigors of field work.

The transmitter is lightweight and comfortable for talent to wear, while the receiver mounts neatly onto DSLR or mirrorless cameras using the included shoe mount adapter. A locking connector keeps your mic securely attached, and the onboard mute switch gives you quick control on set.

Clean Signal and Easy Setup

The EW 112P G4 operates on a wide 42 MHz UHF bandwidth with 1680 selectable frequencies, allowing you to avoid interference even in busy RF environments. The auto frequency scan helps you instantly find the clearest channel in your location.

Syncing the transmitter and receiver takes just seconds using the infrared interface. Once connected, the daylight-readable LED displays show real-time information such as battery life, reception quality, and audio levels.

Clear, Natural Sound with the ME 2-II Lavalier Mic

The system includes the ME 2-II omnidirectional lavalier microphone, which captures sound in a natural, intelligible tone optimized for speech. Its 360-degree pickup pattern ensures consistent audio even when the speaker turns their head or shifts position.

To maintain audio quality during transmission, the system uses Sennheiser’s HDX compander technology, which minimizes noise while preserving dynamic range. This helps ensure your audio stays clean, even in noisy or unpredictable recording environments.

Professional Features for Demanding Workflows

• Adaptive-diversity reception provides a stable wireless connection up to 330 feet

• 20 frequency banks with up to 12 compatible channels each help prevent signal interference

• Pilot tone squelch mutes unwanted RF noise when the transmitter is off

• Adjustable receiver output lets you match the input levels of your camera or recorder

• Four-step battery indicators on both units help you monitor power in real time

• Auto-lock function prevents accidental changes during a shoot

• RF mute option available for silent pauses without turning off the system

Both units can run up to 8 hours on AA batteries or optional BA 2015 rechargeable Accupacks. When using Accupacks, they can be charged directly via side contacts using the L 2015 charger (sold separately).

Compatibility and Expandability

The EW 112P G4 is fully backward-compatible with previous Evolution Wireless generations, including G1, G2, and G3. You can mix and match with handheld, plug-on, or other bodypack transmitters, as well as receivers from the EW 100 and EW 500 series.

This flexibility makes it a great choice for growing production setups or for users who already own other Sennheiser wireless gear.
