Step 1 Mount the Audio Digital Power Amp IC (IC5000) to the
D-Amp P.C.B.
Caution: Ensure pins of the Audio Digital Power Amp IC 
(IC5000) are properly seated and soldered on D-Amp P.C.B.
Step 2 Screw the TR spring to the heatsink unit A.
Step 3 Use a blower to remove the minute particles that might
be caused after the process of the screwing TR spring to the
heatsink unit A.

Step 4 Solder pins of the Audio Digital Power Amp IC (IC5000)
on the solder side of D-Amp P.C.B.

Step 5 Position the bottom chassis portion in to the curves
according to the diagram shown. (Rotate the part at 180
degrees as compared to its original position)
Step 6 Screw the portion to the bottom chassis.

• Follow (Step 1) to (Step 3) of Item 6.3.
