Note – When converting from 8SE to CD82 you will no
longer be able to decode the extra information on the few
HDCD discs available, however the sound quality offered by
the CD82 upgrade is significantly superior on all discs to
that of the original 8SE.

Upgrading an Alpha 7/7SE, 8/8SE to CD82 DAC
For 7/7SE follow steps 1,2,3A onwards (not 3B)
For 8/8SE follow steps 1,2,3B onwards (not 3A)
1. Disconnect the mains supply from the Alpha CD player.
2. Remove the top cover by taking out the 2 screws from the
top edge of the rear panel marked ! (Pozi no.1 driver
required and on each side marked " (Pozi no.2 driver
required).
3A. For Alpha 7/7SE to DiVA CD82 DAC upgrade only
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 sockets will
pass.
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.
Fit the 2 supplied PCB (printed circuit board) pillars to the
holes in the main board on either side of the flex foil
coming from the display board, these are marked # in
figure 1. The big end of each PCB pillar goes into the
main PCB, these push in and clip home. Take great care
not to damage the main circuit board.
Remove the Alpha 7/7SE 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.
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.
3B. For Alpha 8/8SE to DiVA CD82 DAC upgrade only
Remove the 5 screws holding the Alpha 8/8SE board in
place. Squeeze the top of the two PCB pillars supporting
the end of the aluminium extrusion and lift the extrusion
up and out of the unit. If the flex foils do not come away
with the DAC board then remove them as well.
4. Take static precautions first. With the aluminium
extrusion of the CD82 DAC module uppermost fit the
flex foils from the module into the appropriate sockets
in the main board, ensuring they are pushed fully home.
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.
5. Push the module down firmly on to the support pillars,
ensure it is latched in place.
6. Fit the supplied screws with integral washers to the 5
points marked $ in figure 1 (T10 Torq driver required)
to hold the module in place.
7. Refit the top cover and attach the CD82 authentication
label to the underside of the CD player

8. Remove the following jumpers: - PL2, PL3, PL4, PL6
Fit the following jumpers: - PL5, PL7
9. Take static precautions first. With the aluminium
extrusion of the CD82 DAC module uppermost fit the
flex foils from the module into 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.
10. Push the module down firmly on to the support pillars,
ensure it is latched in place.
11. Fit the supplied screws with integral washers to the 5
points marked $ in figure 1 (T10 Torq driver required)
to hold the module in place. Refit the top cover.
