B-4 A UDIO C ONNECTOR W IRINGBalanced Analog Inputs and OutputsThe analog audio inputs are direct-coupled, differential stages with 6k ohminput impedance (each leg). The three-pin XLR connec<strong>to</strong>rs are wired pin 2hot. Balanced analog inputs should be wired as shown in Figure B-4.AnalogOutputXLR-3MXLR-3F<strong>Sonic</strong>Analog Input100 pfOut ---31k004k994k99Out +++21k004k99-+Out gnd1CaseSee NoteShield1Case2x220 pf4k992x220 pf100 pfFigure B-4Connecting Balanced Analog InputsNote that whether or not you connect the shield at the source end of thecable depends upon the output configuration and grounding of the sourceequipment.For example, if the source equiment signal ground is not connected <strong>to</strong>earth, then you can carry the shield through <strong>to</strong> pin 1 of the source output.If the source signal ground connects <strong>to</strong> earth, however, then carryingthrough the shield will increase the likelihood of ground loops. In this case,you should leave the shield unconnected at the source, forming atelescoping shield.
