The ADJ 4ST100 4 Stream DMX Bridge is a specialized wireless control interface designed to enable and expand the capabilities of the ADJ Airstream DMX Pro wireless lighting control ecosystem. This device acts as a central hub, translating between standard wired DMX512 signals and ADJ's proprietary Airstream wireless protocol. Its primary function is to receive up to four independent universes of DMX data via wired XLR connections and transmit them wirelessly to compatible Airstream receivers, which then output standard DMX to control fixtures. This eliminates the need for long, cumbersome DMX cable runs, providing exceptional flexibility for lighting setups in theaters, touring stages, event productions, and installations where cabling is impractical or time-consuming to deploy.

The bridge is engineered for reliability in performance-critical environments. It supports four separate DMX universes (often labeled A, B, C, D), allowing complex, multi-universe shows to be transmitted from a single unit. The wireless transmission uses a robust, license-free frequency band with advanced error correction to maintain data integrity and minimize dropouts. The unit typically features an LCD screen for status monitoring of signal strength, battery level (if battery-powered), and channel activity. It is designed for easy integration into existing setups, allowing lighting operators to use their preferred console to output standard DMX, which the bridge then converts and broadcasts.

Physically, the 4ST100 is built in a rugged housing suitable for road use and can be powered via AC adapter or internal batteries for complete mobility. By serving as the critical link between a traditional DMX console and wireless fixtures, the ADJ 4ST100 DMX Bridge provides significant setup time savings, reduces cable clutter and tripping hazards, and unlocks new creative possibilities for fixture placement, making it an essential tool for modern, adaptable lighting control.
