3. Place your DAC upside down on the white cleaning cloth with the rear panel facing
towards you.
4. With the Phillips screw driver, remove the four 4-40 head screws shown in circles
below. No need to save these screws your kit has new ones.

7. Uniformly push down on the sides of your DAC. The top will pop up as shown below.
8. Reach under the top cover and lift it out of the chassis, flip it over to the left and set it
down on the left side of the DAC as shown in the photo below.

come off the top cover and fallen into the unit. There
should be 9 pieces of gasket material on the top panel in
the locations shown below. Replace any loose pieces by
pressing them back onto the metal where shown below.

connector to prevent the rear panel from being scratched and use the ½” open end
wrench to remove the nut from the RCA connector.

Identify your Analog Output Board - Type A or Type B?
There are two types of analog output boards. The Analog Output Board is the larger
bottom board. How the Mark II Digital Input Processor board connects to the Analog
Output Board depends on whether it is an A or a B style of Analog Output Board. The
next step is to identify if you have either an A or a B style Analog Output Board. Once
you have identified the style, proceed to the A or B installation section to finish the
installation.
Type A Analog Output Board
21.You’ll note that the Type A Analog Output Board has a small black twelve pin
socket (J3 page12) adjacent to the two large power supply capacitors.
22.If your Analog Output Board has this socket you will use this short (3 inch/7.5cm)
I2S cable.
The I2S cable is labeled with four acronyms.
23.1. MCK (Blue) 2. BCK (Yellow) 3. DAT (Red) 4. LRCK (White).
24. These acronyms will correspond to the colour code on the new MKll Digital Input
Board I2S input coaxial sockets.

Type B Analog Output Board
25.You’ll note that the type B board has a 16 pin socket, labeled J2, on the right hand
side (looking from the rear of the unit) between the metal support posts.
26.If your Analog Output Board has this socket you will use the long (6 inch/15cm) I2S
cable shown below.
The I2S cable is colour coded and will correspond to the colour code on the new
MKll Digital Input Board I2S input coaxial sockets.
