Power/Data Cable
The Power/Data Cable uses 4-pin XLR connectors on either end and consists of two 14
AWG conductors and a 22 AWG twisted, shielded pair. The shells of the two XLR
connectors are not electrically connected together -- this prevents large power currents
from flowing from chassis to chassis of the equipment. The twisted pair shield is
connected at male XLR connector end only.
