What is Wireless Dimming?

Check out our informative tutorial and demonstration videos.

Using batteries for power and wireless DMX for control, RC4Magic wireless dimming puts lighting in costumes, props, set pieces, turntables, and more. Controlled from your DMX console, seamlessly integrated into your scenes and cues, RC4Magic devices are transparent to the lighting designer, as responsive and robust as any other fixture in your show.

“Inspired by the Apple iPhone and the Leatherman multitool,
RC4 Series 3 technology delivers unparalleled versatility
to propmasters and show electricians around the world.”

RC4Magic Series 3 DMXio Transceivers

Unique IDs Ensure Superior Data Protection

As a system transmitter, the DMXio decodes the incoming DMX universe, encodes and encrypts it with your unique digital system ID, and broadcasts it using Direct Sequence Spread Spectrum (DSSS) digital radio. Unlike wired DMX, the broadcast signal includes error checking and correction codes, and is not affected by minor interruptions and interference.

As a receiver, the DMXio decodes the rf signal from the transmitter, rebuilds the DMX universe, and regenerates a standard DMX signal with the same number of channels and the same packet rate as the data going into the transmitter. DMX in and out are compliant with USITT DMX512/1990.
