Description
The Nevaton VR is an ambisonic microphone (four capsules in a tetrahedral arrangement), designed for 360° spatial recordings in the highest quality.
Decades of engineering experience in manufacturing top-of-the-range microphones are condensed in this new model.
The NEVATON VR features:
- Incredibly low self-noise (4dBA)
- Ability to handle very high sound-pressure levels (142dB)
- Switchable attenuation: -10dB
Note: The -10 dB reduction is achieved by decreasing the polarization voltage (from 60 V to 20 V).
—> This additionally allows the membrane to respond quickly to very loud sounds! - Switchable Low-cut filter (80Hz, 6dB/Oct)
- Heated capsules (for parameter stability in diverse climatic conditions): Two switchable heating modes:4mA or 8mA heating current
- Using the 8 mA switch position also allows to use long cable-runs (length of more than 200 meters)
- RF filter against radio interference
- Switchable LED – the LED can be switched off, useful for filmed stage performances etc.
The microphone comes with a 10pin -> 4 XLR3 cable, with a standard cable length of 3 m (longer cables upon request)
An additional cable (10pin->10pin) for the output from the windscreen is also available.
Dedicated filtersets for format conversion (Ambisonics A to B format) are available:
They have been developed by Professor Angelo Farina, a capacity on the field of Ambisonics and acoustic researcher at the University of Parma. You can download the filtersets here – DOWNLOAD
