Audio, video and digital inputs and outputs

For optimum performance improvement with RCA jacks, connect a purifier at (or as close as physically possible to) the positive terminal of the jack, and a second purifier on the return leg. Treating only the positive leg will also enhance performance, but to a lesser degree. For XLR balanced input jacks, both hot and neutral must be treated. For XLR output jacks, best results will come from additionally treating the ground -- although here too, the purifier for the ground may be omitted, with some lessening of the performance improvement.

The best results come from treating inputs and outputs. However, if that approach is too expensive, excellent results can still be achieved. As a rule, placing the purifiers at inputs is slightly more effective than putting them on outputs. Note: When upgrading a preamplifier, the input modification should be placed after the selector switch, so that the input signals from all source components get the benefit. In addition to the standard modifications described above, there are other locations that can be modified to further improve performance. Bybee Technologies can provide consultation on these other performance-enhancing modifications if a schematic for the circuit is available.
