This example of a back panel has three pairs of RCA inputs and two pair of RCA outputs.
————————————————————————————
Wire the Input Jacks to the RAKK Input board
Each input jack will be individually connected to the RAKK Input board so there is no common
input grounding on the panel. However, XLR jacks will have their shield (pin 1) connected to the
chassis at the connector.
Repeat each instruction for each jack. Use a #22 blue/black twisted pair for the left channel and a
#22 orange/black twisted pair for the right channel.
It takes a lot of heat to solder the shell of the Cardas RCA jacks – you may want to use a
soldering gun to solder the shell.
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 a 1¼” twisted pair to each XLR jack. Solder the blue (orange) wire to pin 2 and the
black wire to pin 3.
3.
For each RCA jack, make a twisted pair from a 1¼” blue (orange) wire and a 1¾” black wire.
Solder the blue (orange) wire to the center post and the black wire to the shell of the jack.
4.
Dress the left channel wires toward the top of the panel and the right channel wires towards
the bottom of the panel.
5.
Install the 1” standoffs on the RAKK Input board on the same side of the boards as the
relays.
♪
6.
Mount the RAKK Input board in its location on the back panel.
•
Orient the board such that the input connector is closest to the center of the panel.
•
Secure with four 6-32 x ¼” screws.
