Wire the output jacks:
Even though you may have several pairs of output jacks of different types, they are electrically a
single pair of outputs. The multiple pairs of output jacks are wired in parallel. Use orange/black
for the right channel and blue/black for the left channel.
Observe the labeling on the RCA/XLR (Gnd/Lift) switch. The switch and the labeling may be
positioned in any orientation but will be wired in only one way – such that when the switch is in
the RCA (Gnd) position, the shells of the RCA jacks are grounded. The center two pins are
switched to either of the two outside pins. The switch is constructed so that the switch handle is
pointing in the direction of the two outside pins that are not connected to the center pins. For
example, if the switch is oriented vertically with RCA (Gnd) on the bottom, when the switch is
in the RCA (Gnd) position (down), then the center two pins are connected to the two pins that
are closest to the top of the panel. This orientation of the switch is assumed for these instructions
and your wiring should be adapted to match the orientation of your switch.
1. Notice that there is a metal tab adjacent to pin 1 on the XLR jacks. Connect a wire between
this tab and pin 1 on each jack.
2. Connect all of the positive pins together on the left channel jacks. The positive pin is pin 2 of
an XLR jack and the center pin of an RCA jack.
3. Connect all of the negative pins together on the left channel jacks. The negative pin is pin 3
of an XLR jack and the shell of an RCA jack.
4. Connect all of the positive pins together on the right channel jacks.
5. Connect all of the negative pins together on the right channel jacks.
6. Connect one of the two pins that is closest to the top of the panel on the RCA/XLR
(Gnd/Lift) switch to the shell of one of the left channel RCA jacks.
7. Connect the other of the two pins that is closest to the top of the panel on the RCA/XLR
(Gnd/Lift) switch to the shell of one of the right channel RCA jacks.
8. Prepare a 19" long #22 blue/black twisted pair. Attach this twisted pair to the left channel
output jack that is closest to the input jacks. Solder the blue wire to the positive pin (pin 2 of
an XLR or the center pin of an RCA) and the black wire to the negative pin (pin 3 of an XLR
or the shell of an RCA).
9. Prepare a 14" long #22 orange/black twisted pair. Attach this twisted pair to the right
channel output jack that is closest to the input jacks. Solder the orange wire to the positive
pin and the black wire to the negative pin.
