PS Audio PerfectWave DAC Mk II Upgrade Kit - page 12
The first step in the process of the Type A analog board is to connect the new Mark II digital Input board to
the Type A analog board. To do this you will connect the supplied short I2S cable between the Digital Input
board and the analog board. The short I2S cable looks like this:
It is important to make sure the 4 wires are connected properly for the upgrade to work. Each of the wires
are labeled to match the corresponding connections on the new Mark II Digital Input board.
The black long connector of this cable inserts into the analog board and the individual wires connect to the
matching connectors on the Digital Input board.
33. The I2s cable has a small tab or key on its plug so it will only insert one way into the analog board.
34. Orient the cable so the tab is facing the rear panel.
35. Once you get the cable aligned with the header below use the tweezers to push the cable into the
header on the analog board. This connection is only a snug fit so you do not need much force to mate
the connectors. When you start to push down if you feel the cable start to rock your alignment is not
correct.
36. Nothing more than light pressure will be needed to secure the cable.
37. Plug in each individual coaxial connector to the new MK II digital processing board. It is essential that
the coaxial cables are connected to the correct corresponding
coaxial input on the MKll digital Input board.
38. Plug back the two ribbon cables J10 and J11
39. Now reinstall the MKll digital board using the three 6-32 screws removed earlier
or using the new ones provided with your kit. Replace all of the interface screws
connecting the board to the rear panel. Ensure that all of the ribbon cables are
secure.
40. Copper Tape. (see photograph on page 12)
41. Take one piece of copper tape, the other is a spare, and peel the backing off the self-sticking adhesive
copper tape, form the tape to an “L” shape, and press the tape into the gap between the USB connector
and the rear panel as shown below to ensure the gap is sealed.
Caution: the edge of the copper is sharp, be careful not to cut yourself!
The Internal installation is now complete.
