The fine folks at Swisson had a lot to show at LDI this year, including a dead-sexy little sinewave dimmer designed for TV studios. The XSD-D Satellite Sine Wave Dimmer can be a switched or dimmable power source and is available in 4×2.5kW, 2x5kW or 1x12kW models. This could be the perfect choice for someone needing to dim one or two very large studio or motion picture fixtures. By using sine wave technology, the XSD-D avoids all the filament hum issues that arise with very large filament lamps, making this a viable option for quiet sets. The unit features onboard and DMX control, and can daisy-chain to link multiple units together.
