Fast, Secure Wireless DMX Transmission and Distribution

The RC4Magic-900SX DMXio-HG transceiver is ideal for dimming lamps, LEDs and more, while providing state of the art security and best-in-class, congestion-free 900MHz wireless dimming for customers in the USA, Canada, Brazil, Australia, and New Zealand.

The 900SX DMXio-HG transceiver is a smart device that automatically detects other wireless transmitters, and will automatically switch to receive mode. Manually switching modes is as simple as a push of a button.  The 900SX DMXio transceiver—working with another 900 SX DMXio or with another RC4 900SX wireless DMX device- is the ideal hub for all wireless 900MHz dimming in theater, arenas, films, television and even in architectural applications.

900MHz avoids the congested 2.4GHz band and provides a fast, reliable, secure signal up to 600 feet (180m) or more inside theatres and other performance spaces, and to 1000 feet (300m) or more outdoors. Three DMX universes—and occasionally more- can operate safely and reliably in the 900MHz band, thanks in part to RC4 System IDs. This means interference-free operation anywhere, anytime.

Watch our hands-on tutorial video about DMX cable replacement using the DMXio.

RC4Magic-900 operates in the 902-928 MHz RF band, licensed ONLY for use in Canada, USA, Australia, Brazil, and New Zealand.  In other jurisdictions, including Europe, Asia, Africa and international tours, our 2.4GHz RC4Magic Series 3 system is ideal.


When they had to go wireless in the wilds of Oregon, the Darklight lighting team turned to the 900SX DMXio-HG Transceiver.
