Encrypted 24 Bit Audio From 100 Feet. The Sennheiser AVX Digital Wireless Handheld Set transmits wireless handheld microphone audio in 24 bit quality up to about 100 feet in normal operation conditions. The kit is designed for simple, plug-and-play set up with automatic sensitivity adjustment and automatic frequency switching to ensure clean audio is sent through a clean channel. With its focus on simplicity the AVX kit lacks the finer RF background options of the Sennheiser G3 system. The AVX kit works in the 1.9 GHz band. It’s license free, and theoretically the only other kinds of products that use this range are cordless telephones.

AVX-835 Handheld Microphone Transmitter. The AVX 835 hand held microphone is a high quality microphone capsule with an integrated transmitter contained within a rugged metal housing. A frequency response from 50 to 20,000 Hz ensures accurate sound reproduction and 154 dB SPL handling keeps distortion of loud sources at a minimum. The mic’s rechargeable BA 10 battery will last you anywhere from 10 to 15 hours dependant upon the working range of your project.

AVX EKP Wireless Receiver. The EKP receiver will be the most interesting change for those coming from the Sennheiser G3 system. An XLR connector is built into the unit and gets rid of the need for an additional cable and mounting solution for receivers. Just plug it into the XLR port of your camera or recorder, and voila. You’re now mounted and ready to record. The XLR port twists to make attaching easier, and the unit can read the phantom power output of your device to turn on and off automatically. You don’t have an XLR port on your camera? No worries. We include an XLR to 1/8" (3.5mm) adapter cable for plugging in to mirrorless and DSLR cameras with mini plug audio ports. Expect four hours of continuous use before having to swap the receiver’s BA 20 battery.
