Input and Output Connections
Gold-plated XLR connectors are used for inputs and outputs. The input con-
nector is female and the output male.
All connectors are wired according to AES standard: pin 1 is ground (shield),
pin 2 is “high” or “+,” and pin 3 is “low” or “-.” A positive voltage on pin 2 of
the input will result in a positive voltage on pin 2 of the output
Grounding and Shields
A full discussion of proper studio wiring schemes is beyond the scope of this
manual, but, in general, the Input mating XLR connector must have the cable
shield connected to pin 1.
Whether the shield is connected to pin 1 of the output connector depends on
the standard in your studio. The shield should be connected to ground at only one
end of the output cable; however, although not recommended, the shields can
often be connected at both ends without a problem.
