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
Upgrading a CD72 to CD82

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. 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.

CD72, CD82 & CD92 (text)
Circuit Description
Summary
The main Motherboard/Display PCBs for the Diva CD players
may be assembled as three different versions:
! DiVA CD62 (text) - With alternate components fitted
and the 92DAC upgrade connections omitted
(L933AY).
! DiVA CD72 (text) - With the standard set of
components fitted (L899AY).
! DiVA CD82/92 (text) - With analogue components
and connectors omitted, for use as a host motherboard
for the plug-in 82 or 92DAC (L934AY).
The CD72T version may be converted for use with an upgrade
plug-in DAC board by changing on-board jumpers.
All systems are based on a Sony kit, comprising CDM14BL-
5BD25 CD transport / loader / laser mechanism, micro-controller
and fluorescent display.
Power Supplies
The CD72, CD82 & CD92 transformers :-
! 230/115VAC - part number L866TX
! 100VAC only - part number L851TX
The mains transformer has three secondary windings:
1. 13.7V – 0V – 13.7V to provide ±12V(A) supplies
(IC201 and IC205) for the audio output circuitry via
regulators IC201 and IC205.
2. 9V-0V-32V to produce the digital, motor drive and
fluorescent display grid supplies:
+11V(U) Unregulated supply for relay drive and
+5V(D) supply
+7V (IC200) Mechanism and motor driver
supply
+5V(D) (IC202) General digital logic supply
+5V(A) (IC203) Supply to DAC
-30V (IC204) Display grid voltage.
3. 0-5V to provide an AC supply for the display
filament.
All of these supplies are delivered also to the optional CD82 or
CD92DAC upgrade board via the DAC power connector SK203.
The supplies are conventional and are linearly regulated by 3-
terminal voltage regulators.
When the DAC upgrade board is used, analogue regulators IC201
and IC205 can be bypassed by removing JP203 and JP205, and
fitting JP202 and JP204
since regulation is contained on the
DAC board itself. Soft-charging resistors R204 and R205 are
bypassed similarly.
Relay Mute Control
This circuit drives a relay to un-mute the analogue output ~5
seconds after the unit is powered on, and quickly mutes the
output when the unit is switched off. The circuit works
effectively as an “AND” gate.
If AC is present on the transformer secondary winding and the 5-
second timer composed of R222 and C221 has reached the
threshold voltage (Vbe of TR200 + Vbe of TR201 - Vce of
TR202, or ~1.0V), the relay coil is connected to +11V
(referenced to 0V_3 as required by the DAC’s internal circuitry)
via TR204.
When AC is removed, C231 discharges quickly through R225,
the base voltage of TR204 rises and the relay coil voltage is
removed, muting the output.
TR203 resets the ‘timer’ by discharging C221 quickly at turn-off.
Remote Control/PIC Micro
Remote controldata is received from the IREye on the displayPCB
and buffered by TR300 and TR301. The Programmable Interrupt
Controller converts the RC-5 format data into the NEC format
required by the Sony micro. The PIC also controls the configuration
of the digital filter/DAC on the DAC board.
Motor Driver
The status of the drawer is indicated to the micro by two micro
switches ‘INSW’ and ‘OUTSW’ on SK205. The micro controls
the drawer motor via driver IC303.
Clock Buffering
The clock and data signals LRCK, ADATA and BCLK from the
mechanism connector SK300 are double buffered by IC300
before being delivered to the DAC.
Power-On/Reset
The power-on reset signal XRST (or RESET) is generated by
R409, C410 and IC404. When the power is turned on, C410 is
initially uncharged and pin 11 of IC404 is at high voltage, and
thus the output is low. After a short time, C410 is charged via
R409; IC404 pin 11 is then low, and the output switches high
(RESET is de-asserted).
DAC & System Clock
The DAC is a Burr Brown PCM1716E, the DAC is configured
for hardware control.
Digital audio is input on pins 1, 2 & 3 in standard Red Book
Audio format, i.e. Word Clock, Bit Clock and Data.
The system clock is based around 16.9344 MHZ crystal X400
and transistor TR402. This produces a stable clock with low
jitter. IC404A & B buffer the clock as linear buffers. IC404C &
D buffer the individual mech & DAC clock lines.
The CD82 & CD92 system clock is generated on the DAC board.
The clock and data signals LRCK, ADATA and BCLK from the
mechanism connector SK300 are double buffered by IC300 before
being delivered to the DAC. The system clock is delivered to the
mech via two-position jumper PL300. The clocksource is selected
to be either from the main board (CD62/72) or from the DACboard
(CD82/CD92) by the position of JP300.
When the 82 or 92DAC is fitted as an upgrade to aCD72,removing
JP400 disables the main board clock

Analogue Output
Left channel:
IC400A and IC400B are cascaded 69kHz 2nd order low-pass
Bessel filters. The output devices internal to both op-amps in
IC400 are “pulled down” to the negative supply rail to force
operation in class A (one output device is conducting at all times
and crossover distortion is eliminated).
IC402A is a DC servo with a very low cut off frequency, acting
to impose a non-zero voltage ‘virtual earth’ at the non-inverting
input of IC400B, thus eliminating the offsets caused by the pull-
down resistors and DC-coupling the output.
The right channel is the same as the left channel. IC401A & B
are used as the buffer and filter.
Microcontroller & Display Board
The system microcontroller IC100 serves the following functions:
! Control of the mechanism & decoder on the CDM14
mechanism
! Control of mute, attenuation and de-emphasis for the
DAC
! Direct drive of the fluorescent display
! Remote control decoding
! Keyboard scanning
! 82/92DAC muting
The keyboard scanning works by connecting the keys to a resistor
ladder on an ADC input to the micro. Pressing a key presents a
unique voltage to this input, which the micro is pre-programmed
to interpret accordingly.
The remote control data contains a ‘Customer Code’ that
identifies this as an Arcam product. The diode network D100 to
D106 configures the micro to accept this code.
Remote Bus Carrier Filter & Demodulator
Remote control commands can be delivered over wire to SK500
for multi-room applications. Incoming signals are attenuated and
clipped by resistors and D500. L500 and C508 form a parallel
resonant circuit at approximately 37kHz. This demodulates the
incoming signal and the output is passed to IC501A where it is
‘chopped’, low pass filtered and fed to IC501B to provide the
RC5 output signal.
Digital Output
The decoder on the mechanism assembly generates an SPDIF
format digital output signal. This is passed to buffer IC500A.
IC500B through E are used in parallel to provide a transformer
less 75-ohm source impedance to a single phono socket SK501.
Optical digital output via IC502 is also tapped off the digital
output signal via IC500F.
