CD72/CD92 Circuit Description
SUMMARY
The Main PCB for the DiVA CD72/92 player may be built as two different versions: ! ! With all components fitted for the Alpha CD72 (L887RS) With audio components and connectors omitted, for use as a motherboard for plug-in DAC module L816 (L888RS) for CD92
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. The remote control data contains a `Customer Code' that identifies this as an Arcam product. The diode network D291 to D297 configures the micro to accept this code.
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 Z210.
The CD72 version may be converted for use with a upgrade plug-in DAC board by removing a configuration connector. The system is based on a Sony kit, comprising CDM14-5BD10 laser mechanism & loader, micro-controller and fluorescent display. The PCM 1716, as per the 1710, can be operated in either Software or Hardware mode. The default for the CD72 is hardware mode.
DAC & System Clock
The DAC is a Burr Brown PCM1716. Mute, attenuation and deemphasis functions can be controlled via a 3-wire serial link from the system micro to pins 26, 27 & 28 via resistors R31 R32 & R33 respectively. Currently resistors R31 to R33 are not fitted and the DAC is configured for hardware control. Digital audio is input on pins 1, 2 & 3 in standard Sony format, i.e. Word Clock, Bit Clock and Data. The system clock is based around 16.9344 MHZ crystal X1 and transistor Q2. This produces a stable clock with low jitter. Z202E & D provide amplification and buffering to the DAC.
Power Supplies & Reset/Mute
Selection for 230V or 115V mains operation is made by inserting a fuse into the appropriate position. The mains transformer has three secondary windings: 1. Provides +12V and -12V supplies for the audio output circuitry via regulators Z204 and Z205. This produces the digital, motor drive and fluorescent display grid supplies: (Z206) (Z208) (Z207) (Z203) (Z209) Mechanism and motor driver supply General digital logic supply Supply to DAC Supply to system clock generator Display grid voltage.
Analogue Filters
Z1A (& Z101A) provides the basis for a 2-pole filter. Z1B (& Z101B) buffer the audio and set the output level.
2.
Digital Output
An SPDIF format digital output signal is generated by the decoder on the mechanism assembly. This is passed through isolating transformer T202 to a single phono socket SK5. Optical digital output via Z2 is also tapped off the digital output signal. Power is supplied to Z2 via Z3 a 78L05 regulator.
+7.3V +5V +5V +5V -30V 3.
Provides an AC supply for the display filament.
Upgrade to CD92
The CD72 includes a configuration PCB connected to PL1. This provides power to the DAC and clock generator, connects the digital audio and system clock signals to the DAC and provides additional clock buffering with Z4 A&B . Removing this board removes these connections and allows the system clock generated on the DAC board to pass through to the CDM14.
The power-on reset signal XRST is generated by R17 and C29. When the power switch is turned off one of its poles discharges C29 quickly. This, along with the AMUTE signal from the micro, controls the output mute transistors via level shifter Q3.
Remote Control/PIC Micro
The PIC micro 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.
Micro controller & Display Board
The system micro controller Z212 has the following functions: ! ! ! ! ! Control of the mechanism & decoder on the CDM14 Control of mute, attenuation and deemphasis for the DAC Direct drive of the fluorescent display Remote control decoding Keyboard scanning
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.

Hints & tips
! ! ! !
When upgrading from CD72 to CD92 remember to fit the steel plate to the transformer, this reduces noise. The CDM14 mech ( part no. B2009 ) is interchangeable between the Alpha7 series and the DiVA CD72/92 non text version. Please note that the CD72/92 TEXT units use a different mech ( part no. B2012 ), the display and main boards are also different and therefore are not interchangeable parts. Voltage conversion 230/115VAC by changing the internal fuse position and fitting the correct rated fuse. 100VAC requires a different transformer.
