American DJ D4 Branch RM Single Rack 4-Way DMX Distributor/Booster w/XLR IO Jack

The D4 Branch RM takes one incoming DMX signal and splits it into four separate outputs, each electronically isolated from the others and each with a dedicated driver that boosts the signal back to full strength. Isolation is the part that saves shows: a fault, a bad cable or a failed fixture on one branch stays on that branch instead of taking down the whole universe.

Both 3-pin and 5-pin XLR connectors are provided on inputs and outputs, so it drops into a mixed rig without adapters. There are one 3-pin and one 5-pin isolated input, one 3-pin and one 5-pin passive loop output, and four 3-pin plus four 5-pin isolated outputs. A link/terminate button and a DMX status LED make troubleshooting a matter of pressing a button and watching a light rather than swapping cable by cable.

Boosting matters over distance and fixture count. Long runs and large daisy chains degrade DMX, and flickering fixtures at the end of a chain are usually a signal problem, not a fixture problem. Four boosted branches replace one overloaded chain.

The unit is a single rack space, 19" x 5.5" x 1.7" at 5.3 lb, with rack ears, screws and rubber pads included so it mounts or sits freestanding. It is fully DMX512 (1990) compliant, CE approved and FCC compliant. Good fits include touring racks, houses of worship, theaters, clubs and rental inventories.
