The D4 Branch RM™ is a single rack space, 4-way distributor/booster with 3pin and 5pin XLR input and output jacks. This unit takes the incoming DMX signal and splits it to four (4) separate outputs that are electronically isolated from each other to ensure uninterrupted data. In addition, each output has dedicated drivers to boost the incoming signal, and the unit includes a link / terminate button for easy troubleshooting.
