Product Overview

The Sennheiser AVX Wireless Vocal Set (SKU 509103) is a complete digital 1.9 GHz wireless system combining a handheld transmitter, bodypack transmitter, ME 2 lavalier, and the compact EKP AVX plug-on receiver in a single kit. Designed for broadcast, corporate video, filmmaking, and mobile production, the AVX system uses automatic frequency management and self-configuring digital transmission to eliminate manual RF setup entirely. Operating license-free in the 1.9 GHz band, it is suited for ENG, EFP, interview, and small conference room wireless deployments where speed of setup and audio quality are priorities.

Product Description

The AVX system is built around the EKP AVX plug-on receiver, a compact unit that mounts directly onto a camera or recorder’s XLR input and powers on and off automatically via P48 phantom power — no separate power cable required. Auto frequency management continuously scans the 1.9 GHz band and selects the cleanest available channel without user intervention, supporting up to 12 systems operating simultaneously in range. The SK AVX bodypack transmitter includes the ME 2 omnidirectional condenser lavalier microphone and is powered by the rechargeable BA 30 battery pack. The SKM AVX handheld transmitter ships with the MMD 835 cardioid dynamic capsule and is powered by the BA 10 rechargeable battery. All audio is processed at 24-bit / 48 kHz with AES 256 encryption and greater than 120 dB dynamic range, with a 19 ms system latency. The operating range is up to 30 meters (98 feet) line of sight, suitable for standard interview and conference settings. The included NT 5-10U USB power supply charges the accupacks, and the CI 400 adapter cable accommodates mini-jack connections where needed. No FCC license is required for US operation in the 1.9 GHz band.

No. The AVX system operates in the 1.9 GHz license-free band and can be used in the US without any frequency coordination or licensing.

How many AVX systems can operate simultaneously?

Up to 12 AVX systems can operate simultaneously within the same frequency range, suitable for small panel discussions, multi-presenter conference sessions, or multi-camera video shoots.

How does the EKP AVX receiver mount to a camera?

The EKP AVX plugs directly into any XLR input on a camera or field recorder. It powers on and off automatically with P48 phantom power from the camera, and the receiver body rotates around the XLR connector to prevent collision with other mounted accessories.

Can the ME 2 lavalier be swapped for a different microphone?
