1 LPH // SERVIE MNUL rcam lpha // Service Manual Issue Serial No (Paul Newton July ) ircuit escription The following notes describe the operation of the lpha // players. They include the circuitry on the main, and display Ps but not that on the servo P attached to the mechanism. Power Supplies The mains input is fitted with inductors L,,, to filter electromagnetic interference coming out of the player. Mains transformer T0 has three secondary windings supplying two separate power supplies and an supply for the display filament: nalogue Supply ridge rectifier,,, and reservoir capacitors 0- produce unregulated split rails of about /-V. Z0 and Z0 provide regulated outputs of V and -V respectively that power the opamps in the audio output stage. Since there is no power switch on this secondary, the analogue supplies are always connected. igital Supply Switch SW0- disconnects the digital secondary winding when the 'Power' switch is out. n unregulated supply of about V is produced by the bridge rectifier,,0, and reservoir capacitor. This is then regulated to provide three volt supplies (Z0 general logic supply, Z0 supply, Z0 system clock generator supply) and a.v supply for themechanism and motor drive circuits(z0). -0v supply is formed by Z0 and associated components to power the display grid. Muting When the unit is turned off SW0- discharges capacitor quickly. This along with the signal from the microprocessor, controls the output mute transistors,0 via level shifter. lock Generator The system clock is generated by a discrete oscillator based around and.mhz oscillator X. The output of is amplified and buffered by inverters Z0-E & and sent to the clock input of the Z0. & udio Outputs (lpha only) The is a elta-sigma design from urr rown, the PM0U. The serial digital data from the decoder Z0 is input to pins to. The system clock is input to pin. The is powered entirely from one V supply, although it is split and decoupled between the analogue and digital sections of the device. The analogue outputs from each channel are processed identically.three poles of filtering are provided by the active filter based around Z-. Z- buffers the audio output and sets the output level. Muting is provided by turning on and 0. & udio Outputs (lpha only) This is a similar circuit as the one used on the rcam lpha P but designed for Sony format input data and a better digital filter, the SMP, Z.The digital filter is used with a SMP 0-bit chip, Z, (described here as a PWM noise shaper to avoid confusion with the -bit Latch which follows it). The output from this is re-latched by Z, Z. igital Filter PI micro on the mother board controls the filter with the signals R0 to R. The SM filter has internal pull-up resistors on its inputs resulting in R & R being logic. The SMPT requires several control lines from the PI... R FSEL, Selects sampling rate for de-emphasis.

R MLEN, Serial data latch input for volume control. R MK, Serial clock input for volume control. R0 Not connected. No ither On Silence The digital filter adds dither to the output signal. This improves the low-level performance of the. The PWM filter normally mutes when it detects digital silence to prevent any unwanted noise and idle-tones on the audio outputs when no music is playing. slight click is audible when this happens. Unfortunately, the added dither prevents this mute from operating because it holds it open. detects digital silence on the data input to the filter. When silence is detected, the dither function is switched off

2 LPH // SERVIE MNUL allowing the PWM filter s mute to operate as normal. Mute Relay The mute relay is controlled from the PI micro via R0 after switch-on. In Standby mode, XRST is low which interrupts the relay via. R0 is low when the player comes out of standby mode and goes high after a short settling delay. The power rail, RLYPWR, is un-regulated and has a small reservoir capacitor (on the mother board) so that the relay is released very soon after the mains is disconnected from the player before the other power supply rails collapse. PWM noise shaper To reduce EM, the clock signal going into this chip, Z, is very weak on the XTI pin () pin, taken directly off. This is amplified so that there should be a larger signal on the KO pin (). The PWM output on pins,, and can be resolved into an audio waveform on a scope simply by measuring them through a 00K resistor. The same is true for the PWM signals through the latch and the level shifter. latches, Z and Z.The power supply for these chips is the voltage reference and the output drives the analogue filter stage directly. The latches reduce any edge-timing jitter induced on the PWM signal coming from Z. nalogue filter The first half of the analogue filter, Z and Z is balanced. The signal through one side of the op-amp, pin, should be phase inverted with respect to the other, pin. These signals should be viewed on a scope through a 00K resistor since there may still be quite a lot of RF noise on the signal. Z and Z filter the audio signal further and also convert the balanced signal into a single ended signal. Z acts as a servo to reduce the output offset voltage. This has a very large time constant so an offset as high as 0mV is possible when the unit is first plugged in. This reduces to less than mv after 0 minutes and stays low if the unit is switched off and on with the Standby button.

This is passed through an isolating transformer, T0, to the digital output socket SK. System ontroller The XPP system controller (Z) is a combined player controller, keyboard scanner, remote control decoder and fluorescent display driver. It's clock is generated by.00mhz resonator X0. The controller detects the position of the disc drawer from the status of two microswitches, INSW & OUTSW, on socket SK0. The drawer motor is controlled via motor driver Z0. Unplug the unit from the mains.. Push the tray front upwards to remove it from the tray. Push the tray in manually.. Remove the screws holding the front panel to the chassis and release the locating tabs.. Unplug the flexfoil from the display board where it enters the main pcb.. Remove the screws holding the remote receiver pcb in place.. The front panel can now be pulled off the unit.. To remove the display pcb remove the screws holding the board in place. To remove the main pcb first remove the board if it is an lpha or player.. Remove the screws holding the audio output sockets to the rear panel and screws holding the aluminium extrusion in place.. Squeeze the tops of the pcb pillars and lift the board up slightly to clear them.. Remove the flexfoils from the board. The board, still attached to the extrusion, can now be removed from the unit. To remove the main pcb remove the pcb securing screws and the screw holding the digital ouput socket to the chassis. (On lpha s also remove the screws securing the audio ouput sockets in place). Release the cables which connect the mechanism to the main board. The main pcb can now be slid out of the case. The keyboard scanning works by connecting the keys to a resistor ladder on an (analogue to digital convertor) input to the microcontroller. Pressing a key presents a unique voltage to this input. The signal from the remote control receiver is input to RMIN (pin ) after first passing through the PI microcontroller, Z, on the small remote receiver pcb. This PI ic converts the R- format codes from the remote control handsets to NE data, suitable for the Sony chipset. It also controls theconfiguration of the digital filter/ on the lpha and boards the The remote control data contains a customer code that identifies it as an rcam product.the microcontroller is confiqured to accept this code by means of the diode network to. isassembly For Servicing To remove the boards within the players follow the instructions below.. Remove the top cover.. Press load to eject the tray.
