Notice: Be sure to follow figures two and three
when making your own cables. Do not use the
ground lug on the XLR connector. Do not connect
the cable's shield conductor to the ground lug or
allow the shield conductor to come in contact with
the XLR's outer casing. Grounding the shield could
cause a short circuit and erratic behavior.

Special Note: Line Termination. When longer runs
of cable are used, you may need to use a termi-
nator on the last unit to avoid erratic behavior. A
terminator is a 110-120 ohm 1/4 watt resistor which
is connected between pins 2 and 3 of a male XLR
connector (DATA + and DATA -). This unit is inserted
in the female XLR connector of the last unit in your
daisy chain to terminate the line. Using a cable
terminator will decrease the possibilities of erratic
behavior.
