OSCA-DXVF Video Fader

Building on the success of the proven Nemesis DMXVF video fader the new OSCA-DXVF adds OSC and other advanced features  whilst still maintaining all the old favourites.

The OSCA-DXVF is a Dual Channel DMX and OSC Controlled Video Fader designed to allow users to restrict light emission levels from monitor screens - particularly those mounted in an auditorium - when darkness is required during a production.

The OSCA-DXVF maintains video sync signal during a blackout avoiding ugly 'Signal Lost' messages which would otherwise be shown on modern LCD screens.

The exact brightness can be faded directly via OSC or DMX from 0 to 100% in 1% increments, effectively treating the video screen brightness like a conventional lighting fixture.

The OSCA-DXVF can form part of an extensive OSC network allowing lighting, sound, stage management and other departments to all control screen brightness if required.


With the addition of a OSCA-R5 button box different presets or states can be controlled at the push of a button allowing, for example, a musical director to dim certain screens as-and-when they wish.

Under DMX control the OSCA-DXVF can directly interface with all modern lighting consoles.
