Upgrading a CD72 to CD92
1. Disconnect the mains supply from the DiVA CD player.
2. Remove the top cover by taking out the 2 screws from the top edge of the rear
panel (marked 1) and on each side (marked 2).
3. Pull off the sticky plastic gasket between the digital output socket and the
audio output sockets to reveal the 4 audio output socket holes through which
the DAC board sockets will pass.
4. Any remnants of adhesive can be removed by rubbing it gently with your
finger and rolling it off. We do not recommend the use of solvents.
5. Fit the 2 supplied PCB (printed circuit board) pillars to the holes in the main
board on either side of the flexfoil coming from the display board. These are
marked 3 on the drawing overleaf. The big end of the PCB pillars goes into
the main PCB. These push in and clip home. Take great care not to damage
the main circuit board.
6. Remove the Configuration Module (the small vertically mounted PCB in the
centre of the main board). It will not be needed once the new DAC board is
fitted.
7. Note: The original nickel plated audio output sockets are no longer connected
after the upgrade and cannot be used. However the digital output still
functions.
8. Remove the following jumpers :- PL2, PL3, PL4, PL6. Fit the following
jumpers :- PL5, PL7.
9. Fit the magnetic shielding plate, by peeling off one side of (E923MC the
adhesive pad) and stick to (E922MC the shielding plate). Then peel the
backing off the other side of pad & Align the top edge with the top of the
transformer and fit centrally. It MUST align with the top edge of the
transformer, if it is fitted to low to the board it may cause shorting.
10. Take static precautions first. With the aluminium extrusion of the DAC
module uppermost fit the flexfoils from the module in to the appropriate
sockets in the main board, ensuring they are pushed fully home. If they are
not pushed fully home, the unit may not read discs. You may find it helps to
slide the module into the unit so that the audio output sockets fit through the
holes in the rear panel and angle the module slightly upwards to achieve this.
11. Push the module down firmly on to the support pillars.
12. Fit the supplied screws with integral washers to the 3 points marked 4 on the
drawing overleaf to secure the module in place. The 2 slightly shorter screws
and the shake proof washers should be fitted to the 2 points marked 6.
13. Refit the top cover, connect the unit to live mains and switch on. Press load to
allow the tray to come fully out and then remove the mains lead from the unit.
Remove the draw front and fit the new draw front with the CD92 / HDCD
logo on.
14. Check the unit functions correctly and if you have an HDCD disc check that a
red glow is seen behind the display window when it is playing.
