Cable Connectors
Cabling must have a male XLR connector on one end and a female XLR connector on the other end.
Caution! Do not allow contact between the common and the fixture’s chassis ground. Grounding the
common can cause a ground loop, and your fixture may perform erratically. Test cables with
an ohmmeter to verify correct polarity and to make sure the pins are not grounded or shorted
to the shield or each other.
