The JMAZ CRMX USB is a compact, USB-powered wireless DMX receiver designed to add reliable CRMX and W-DMX connectivity to compatible lighting equipment. It supports one full 512-channel DMX universe and uses adaptive frequency hopping to maintain stable communication in theaters, concert venues, studios, installations, and event-production environments.
The JMAZ CRMX USB provides a compact solution for receiving professional wireless DMX signals through the 2.4 GHz frequency band. Powered by a LumenRadio QFN48 SMT chipset, it supports both CRMX and W-DMX workflows for integration into compatible fixtures, controllers, and lighting systems.
The receiver handles one DMX universe with up to 512 control channels and supports refresh rates from 1 to 830 Hz. DMX fidelity and connection-error monitoring help maintain accurate, responsive lighting control for live events, theaters, broadcast studios, houses of worship, and permanent installations.
Adaptive Frequency Hopping Spread Spectrum technology continuously manages the wireless connection to help avoid RF interference. With a rated range of up to 1,900 feet and receiver sensitivity of -90 dBm, the unit is suited for both compact venues and large production spaces.
The flame-retardant plastic housing features an internal copper structure, a black exterior finish, and an external antenna for dependable reception. Its fanless design operates silently, while direct 5V USB power allows fast installation without an additional external power supply.
