Reliable Wireless Performance in Any Environment

This camera-mount wireless microphone system includes the ME 2-II omnidirectional lavalier mic, a bodypack transmitter, and a compact receiver that attaches easily to your camera using the included shoe mount adapter. The system's adaptive-diversity reception ensures a stable wireless connection with a range of up to 330 feet, even in challenging environments with high RF interference.

The auto frequency scan feature helps you quickly find the cleanest available frequency, while 1680 tunable UHF frequencies within a 46 MHz bandwidth give you the flexibility to operate up to 12 wireless microphones simultaneously.

Broadcast-Quality Sound with Natural Speech Clarity

At the heart of this system is the Sennheiser ME 2-II lavalier microphone, known for its natural sound reproduction and excellent speech intelligibility. The omnidirectional pickup pattern ensures consistent audio capture, even if the speaker turns their head during a shot.

With Sennheiser's proprietary HDX compander technology, your audio is transmitted without added noise or loss of clarity. This technology maintains high fidelity throughout the signal chain, delivering pristine, professional results.

Durable and Designed for the Field

Built with a rugged all-metal chassis, the EW 112P G4 is ready for demanding production environments. The bodypack transmitter is lightweight and discreet, offering rounded edges for comfort and easy concealment. A locking 3.5mm connector keeps your lavalier mic securely attached, and a mute switch provides quick control when needed.

The receiver's LED display shows real-time information like signal strength, audio levels, and battery status. Synchronizing the transmitter and receiver takes just seconds using the infrared interface, so setup is fast and frustration-free.
