The RC4Magic-900SX DMX2dim is a reliable and secure battery-powered 2-channel wireless DMX dimmer for LEDs, lamps, and motors in small props, costumes, and more. Operating in the 900MHz range, which is free of wireless congestion, the 900SX is the fastest and most secure 2 channel dimmer exclusively available for customers only in the USA, Canada, Brazil, Australia and New Zealand.
