Power
Hub Power Requirements:
48VDC, 150 Watts (each external power supply powers up to 16 Mixers). Hub is capable of powering up to 32 Mixers with an additional power supply.
Mixer Power Requirements:
Power over Ethernet (PoE) 36–52 volts DC, 15 Watts max provided by Hub through CAT6 network cabling
Cabling, Mixers and HBUS
Unshielded CAT6 cables used for Mixers or for HBUS can be run up to 500 feet in ideal conditions (one piece of solid conductor CAT6 with no breaks or couplings). The more breaks/connections/couplings in a cable run, the more limited this distance will be. Poor quality cabling will also limit the maximum distance.
