You may have as few as two pairs or as many as six pairs of input jacks. You may have as few as
one pair or as many as three pairs of output jacks. The jacks may be RCA jacks, XLR jacks or a
mix of the two. Here are some general guidelines for mounting the jacks:
•
Mount the jacks from the inside of the panel.
•
The XLR jacks are secured with two 4-40 x
⅜
” screws and nuts.
•
Orient XLR jacks such that the center pin is on the bottom.
•
XLR inputs use female jacks (with a tab), XLR outputs use male jacks.
There is a switch associated with the output jacks that selects the proper grounding for the jacks.
If all of the output jacks are RCA, then the switch will be labeled “Ground/Lift.”
If there is a mix of RCA and XLR output jacks, then the switch will be labeled “XLR/RCA.”
If all of the output jacks are XLR, then the switch is not needed and will not be present.

Mount the jacks and hardware:
1.
Install the analog input jacks. For RCA jacks, position the red washer on the outside of the
right jack and the white washer on the outside of the left jack.
2.
Install the analog output jacks. For RCA jacks, position the red washer on the outside of the
right jack and the white washer on the outside of the left jack.
3.
If you have chosen to have unused input holes for future expansion, install filler plugs in
those locations.
4.
Install the DPDT toggle switch in the “RCA/XLR” (“Gnd/Lift”) location.
Position the switch so the toggle alternates between the “RCA” and “XLR”.
5.
Install the fuse in the power connector. Note that there is also a place for the spare fuse in the
fuse holder.
6.
Install the power connector from the outside of the panel. Orient the connector such that the
fuse is on the bottom, and secure with two 4-40 x
⅜
” screws and nuts.
7.
Install the solder lug on the inside of the panel, in the hole adjacent to the power connector.
Secure with a 4mm screw and nut. Orient the solder tab away from the power connector and
form the solder tab at a 90-degree angle away from the panel.
