Input Wiring
Balanced Connection
Use this wiring when the source equipment supplies a balanced,
For either input, connect the shield wire of the source sig- nal to the “G” terminal of the input. If the “+” signal lead of the source can be identified, connect it to the plus “+” ter- minal of the input. If the source lead polarity cannot be identified, connect either of the hot leads to the plus “+” terminal. Connect the remaining lead to the minus
Note: If polarity of the output signal versus the input signal is important, then it may be necessary to reverse input lead connections to correct the
Unbalanced Connection
Use this wiring when the source equipment supplies an unbalanced,
For either input, short the input minus
