Wiring the Inputs
Connecting a turntable to the PPA-2 Phono preamp
Phono 1 is Unbalanced only (RCA jacks), Phono 2 can be either Balanced (XLR jacks) or Unbalanced.
Cables from the turntable to the PPA-2 should be as far as possible from AC Mains cables wherever possible. If
they must cross, do so at right angles if you can.
Typically a balanced connection will be more immune to hum, so it would be the preferred connection.
However, you must be careful that the shell of the XLR is not connected directly to the ground line within the
XLR connector. They SHOULD be independent. The shell is the external shield of the cable and connector, and
should be the CHASSIS connection. The ground wire within the XLR is twisted with the (+) and (-) balanced and
should be the signal or tonearm ground. This can all be confirmed with an Ohm meter.
Whichever style you choose, please use the very best cable you can in this location due to the very low signal
levels coming from your phono cartridge.
After you make your audio connections refer to Page 8 to correctly set the DIP switches.
