Rear Panel Connections - D.W. Fearn VLC Operating Instructions Manual

Figure 1. The VLC rear panel connectors
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 (with the Phase Reverse switch set to Normal).
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. With
most microphones, this shield must also be connected to pin 1 at the microphone end of the cable.
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.
