At NAB in Las Vegas, Sennheiser [Booth C2055] is introducing its AVX wireless microphone systems for video cameras. The compact AVX receiver plugs directly into the XLR of a camera, where it automatically pairs with the microphone and switches on when the camera does. The system automatically adjusts the correct audio levels and transmits using a specially protected link in the license-free 1.9 GHz range.
“Whether you’re a journalist compiling a show report, a professional videographer filming a documentary or an in-house marketing specialist making a product video – AVX gives you the room to concentrate on your creative work”, says Sven Boetcher, portfolio manager broadcast & media at Sennheiser. “No licensing is required, the system automatically selects a suitable transmission frequency and also makes all necessary settings – that’s true ease of use.”
AVX comes in ready-to-use systems that contain everything required to go live. Alternatively, systems can be put together from a wide choice of individual components.
Ease of use right from the start
Convenience starts with not having to register the system or pay for its use: AVX operates in the license-free 1.9 GHz frequency range, which can be used in many countries worldwide. The convenience continues in operation: the plug-on receiver automatically switches on with the phantom powering of the camera, and automatically pairs with the transmitter. The system immediately sets the correct audio level, matching it to the camera’s input sensitivity, selects a free frequency – and is ready for the job at hand. If a source of interference appears, AVX will inaudibly shift to a new frequency.
Range on demand
AVX is equipped with adaptive transmitting power, meaning that the system always uses the power that is required to maintain a reliable connection between the microphone and the camera receiver. This not only provides a stable link, it also reduces battery power consumption – as does the automatic on/off function.
Energy management
The AVX receiver and transmitter are powered by special lithium-ion batteries, which can be recharged via a USB port. To avoid nasty surprises when filming for a long time, the transmitters display the amount of battery life remaining.
DSLR accessories included
For DSLRs with a jack audio input, the AVX systems include an XLR-3/mini-jack adapter cable and the mounting accessories needed to attach the receiver to the camera hotshoe.
Sets or individual components
AVX is available in three different sets: with a handheld transmitter (evolution microphone head), with a bodypack transmitter and ME 2 clip-on microphone and in a special professional version with a bodypack transmitter and an MKE 2 clip-on microphone, for film and TV productions.
For the USA, a special combo pack is issued, which includes both a bodypack and a handheld. The microphone head is an MMD 42, the capsule of Sennheiser’s MD 42 reporter’s microphone.
All system components ‑ plus additional items such as a handheld transmitter with on/off switch ‑ are available separately so that users can put together their own AVX systems.
The AVX systems and components will go on sale from June 2015.
