The Sennheiser AVX Camera-Mountable Handheld Wireless Set is designed for plug and record operation with fully self-configuring operation and consists of their EKP receiver and AVX-835 handheld microphone
transmitter. The system provides a variety of automatic functionality
aimed at flexibility and speed.
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. 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. The receiver also detects your
recording input's sensitivity level and adjusts automatically, reducing
distortion and eliminating the need to adjust your mic's level.
The AVX-835 adapts Sennheiser's popular 835 handheld mic for use with the EKP receiver.
