Designed for plug and record operation with fully self-configuring digital operation, the AVX Camera-Mountable Digital Wireless Handheld and Lavalier Set from Sennheiser is well suited for film and video production, as well as electronic news gathering (ENG) and A/V rental houses. The system consists of the EKP receiver, SK bodypack transmitter, an ME2 lavalier microphone, and an AVX-42 handheld transmitter with an MD42 omnidirectional capsule. The AVX system provides a variety of automatic functionality aimed at flexibility and speed including auto-dynamic range settings, which automatically adjusts the audio level to a recording device's input sensitivity, reducing distortion and eliminating the need to adjust your mic's level. The system also offers link protection, a feature that quickly scans available frequencies and will automatically switch before any interference becomes audible.

The EKP receiver has a compact design that plugs directly into the XLR input on your camera or recording device and includes the necessary adapters for use with DSLR cameras. Additionally, the EKP can swivel, allowing it to be used with other attachments mounted to a camera. It powers on and off automatically when it senses 48V from your recording destination, for fast recording and saving battery life when not in use.

It should be noted, that while this system includes 2 transmitters, only 1 can be used at a time.
