The RC4Magic‑900 is a wireless DMX control system built for props, costumes, scenery, and other mobile elements in live entertainment, using the less‑congested 902–928 MHz band for faster, stronger, and more reliable operation than typical 2.4 GHz systems, and approved only in the USA, Canada, Australia, and New Zealand. It uses RC4’s DMXio transceiver and compact battery‑powered dimmers to provide secure Frequency Hopping Spread Spectrum wireless DMX with private system IDs that prevent interference between productions, while features like OneTouch channel assignment, RDM configuration, Digital Persistence for smooth incandescent‑style fades, and effects tools such as ColorMatch, HSL control, and the Flkr Effects Engine make it well‑suited for controlling LEDs, lamps, motors, and small FX elements in demanding theatrical and event environments.
