Sennheiser AVX-ME2 SET-4 Digital Camera-Mount Wireless Omni Lavalier Microphone System (1.9 GHz) - 505861

Product Overview

The Sennheiser AVX-ME2 SET-4 is a complete digital wireless lavalier microphone system engineered for videographers, video journalists, and content creators who need professional-grade audio without the complexity of traditional wireless setups. Operating on the license-free 1.9 GHz DECT frequency band, the system automatically selects clean frequencies and adjusts microphone levels without any manual configuration. The set includes a bodypack transmitter, a compact camera-mount receiver, and the ME 2-II omnidirectional lavalier microphone, delivering a ready-to-shoot wireless audio solution for DSLR and mirrorless cameras. SET-4 designates the specific frequency group for this variant, ensuring compatibility in regions where frequency group 4 applies.

Product Description

The AVX-ME2 SET-4 removes the traditional barriers to professional wireless audio by automating the tasks that normally require a dedicated sound engineer. The system powers on and pairs automatically, scanning the 1.9 GHz DECT band and locking onto a clean, interference-free channel without any user intervention. Automatic level control continuously monitors and adjusts the microphone gain in real time, preventing clipping during loud passages and maintaining an optimal signal-to-noise ratio during quieter moments. The result is consistently clean, broadcast-quality audio regardless of the presenter's vocal dynamics or proximity to the microphone. The ME 2-II omnidirectional lavalier captures natural-sounding voice from any direction, making placement forgiving and reducing handling noise from clothing and movement. The ultra-compact camera-mount receiver plugs directly into the 3.5 mm TRS input of DSLR, mirrorless, and camcorder cameras, fitting neatly in the camera's cold or hot shoe without adding significant bulk. A protected peer-to-peer digital connection between the transmitter and receiver eliminates dropouts and interference from other wireless devices in the 1.9 GHz band. Up to 8 AVX systems can operate simultaneously on the same set without frequency coordination, making it practical for multi-camera documentary or corporate video productions. The BA 30 rechargeable lithium-ion battery in the transmitter delivers up to 15 hours of continuous use, exceeding a full day of production. The system is designed for run-and-gun operation where simplicity and reliability are paramount, but audio quality cannot be compromised.

Technical Specifications

Frequently Asked Questions

Q: Does the AVX-ME2 SET-4 require a license to operate?

No. The AVX system operates on the 1.9 GHz DECT frequency band, which is license-free in most countries. No frequency coordination or regulatory approval is required before use.

Q: What cameras is the receiver compatible with?

The camera-mount receiver is compatible with any DSLR, mirrorless camera, or camcorder that has a standard 3.5 mm TRS microphone input. It is designed to plug directly into the camera without additional cables.

Q: Do I need to manually set frequencies or adjust microphone levels?

No. The AVX system handles both tasks automatically. It scans for a clean channel at startup and uses automatic level control to continuously adjust gain in real time, so you can focus entirely on your shot.

Q: What is the difference between the AVX-ME2 SET-4 and other AVX sets?

The SET-4 designation refers to frequency group 4, which determines the specific 1.9 GHz sub-band the system uses. The AVX-ME2 SET-4 includes the ME 2-II omnidirectional lavalier, whereas other AVX sets may include a handheld transmitter or a different microphone capsule.

Q: How many AVX systems can run simultaneously on the same set?

Up to 8 AVX systems can operate on the same set simultaneously without requiring frequency coordination, making the system practical for multi-camera productions with multiple talent on set at the same time.

Q: How long does the transmitter battery last?

The BA 30 rechargeable lithium-ion battery provides up to 15 hours of continuous operation on a single charge, which is sufficient for a full production day without needing to swap or recharge batteries.

Q: Is the ME 2-II lavalier a directional or omnidirectional microphone?

The ME 2-II is an omnidirectional lavalier, meaning it captures sound equally from all directions. This makes placement more forgiving and reduces sensitivity to head turns or microphone positioning variations during interviews or presentations.

Q: Can the AVX-ME2 SET-4 be used with a boom pole or mixer instead of a camera?

The receiver is specifically designed as a camera-mount unit with a 3.5 mm output. While it can technically connect to any device with a 3.5 mm input, it is optimized for camera-direct use rather than mixer or boom pole applications.
