The GP004 model features Gantom Pro Cable Trunk connectors for DMX and Power input and thru output. This distribution box pairs perfectly with our PP36 PowerPak Plug and Play 24VDC. There is a locking panel mount connector for each of the 8 branch outputs which run to the light fixtures. Pro Cable Branch Extension Cables are available in 1m, 2m, and 5m increments so the user can modularly extend the cable run as needed (up to 30m per branch). Since the GP004 does not require access to the internal circuit board, this model has a housing which is as compact as possible in order to fit into a wide variety of space-constrained applications. CB147 Branch connector caps can be used to make this item IP65 for outdoor installation.
