  • Page 2 L123AY– Connection board and PSU This PCB provides the power for the unit through CON203: +5V_STBY – 5V standby supply L118 RS232, L126 display (on in standby) +3V3 PW338 – L122 PW338 supply (on in standby) 1V8D – L122 PW338 supply (on in standby) +5V_1 –...
  • Page 3 L113AY Component Input – Output board This PCB selects between one of five component video inputs & also provides the output connector for Zone 3 audio. IC100, IC101 & IC104 (LT1675CGN video buffers) require +5V & -5V. The +5V comes direct from L123 & -5V is generated locally from the -15V supply (from L123).
  • Page 4 L114AY – Video input – output This PCB selects between one of five s-video & composite video inputs for the main input & zone 2 video. It also controls the volume control for Zone 2 & 3. The main input video is selected using IC200 (LA73031V video mux) under the control of IC205 &...
  • Page 5 L115AY Digital Input – Output board This PCB selects on of 8 external digital inputs or one of two internal digital inputs & generates BClk, WClk & MClk for the DSP (see L156) & DAC (see L117). It also generates the clocks for the ADC (see L116) when the unit is in ADC mode.
  • Page 6 L116AY Analogue input board This PCB selects the analogue input for the main zone & Zone 2/3 and also digitises the analogue input for processing by the DSP / transmission over SPDIF. One of seven phono inputs (Tape, CD, AV, DVD, SAT, VCR, PVR), Aux (external) input (see L127), AM/FM &...

  • Page 8 L117AY Analogue output This PCB converts the digital audio from the DSP (see L156) to analogue audio. It also configures the use of channels 6 & 7, has the headphone amp, has the RIAA equaliser for the Phono input and handles the multi-channel analogue input.

  • Page 11 EU FM transmissions carrying RDS data. VSM goes to an ADC on the PW338 and provides a signal strength indication. The AM/FM module gives an analogue output which is buffered through a ground balancing circuit (IC302 NJM2114 op amp). IR from the front panel comes onto this board from L126 and goes through a re-modulator circuit (IC200 LMC555) as it has been demodulated on the front panel.
  • Page 12 The FLASH memory is also used to store settings, such as the Arcam specific Cardea keys & MAC address. Note: if the FLASH device is ever changed, it is essential that the original MAC address be programmed into the unit so that the user does not lose and internet radio stations/favourites groups.
  • Page 13 L121AY – Connection board This PCB provides the connections between all the daughter cards, plus the main PCB (L122). IC300 & IC301 (74HC244 buffers) take the clock signals (WClk, BClk & MClk) from L115 & DSP WClk Out & DSPBClk Out from L156 and buffer them to the ADC, DSP &...
  • Page 14 L122AY Main Board This is the main PCB with the PW338 handling the control of the entire unit, as well as video processing. HDMI Rx & Tx functions are performed on this PCB as well as video encoding & decoding. IC200 is main PW338 micro/video processor.
  • Page 15 video outputs active, resolution & copy protection limits apply. Also, when displaying 408i/576i the colour space requirements of the ADV7310 & SiI9134s are incompatible, so if an HDMI display is connected the analogue outputs are muted. The PW338 can only output one clock pulse per pixel, so for 480i & 576i resolutions, a video clock doubler is required (IC504 ICS2402MLF) to convert the 13.5MHz pixel clock (Display Clk) to 27MHz (Display Clk2) under the control of Vid_Clk_Sw.
  • Page 16 Sheet 10 shows the ESD protection devices (IC1000 & IC1004 CM2020) for the two HDMI outputs. There is also provision for turning off the 5V signal to the display device through FETs M1000 & M1001. The two 120 way connectors on sheet 11 show all the connections between the L122 PCB and L122.
  • Page 17 L124AY – Speaker board This conducts the output signals from the power amplifiers on both L125 and L129 to the speaker terminal blocks LS100 – LS103 inclusive, via 4 double pole relays RLY100 – RLY103. The 24V dc supply from the relays is fed from L129 via CON101 pin 18, returning to ground via pin 17.
  • Page 18 Additionally the 3 power amplifier channels in L125 share a common pair of power MOSFET lifters (the part of the block diagram shown as U_Lifter_C) which control the amount of output voltage fed to the collectors of the power transistors in the 3 power amplifiers. The Centre channel Driver Stage starts with the balanced to unbalanced converter IC700B (one half of an NJM2114) which rejects common mode noise on the input when grounded to AGND_FF via the handbag link...
  • Page 19 (equivalent to about 30Watts rms into 8 ohms) then the lifters (fed from Vcc and Vee) are progressively powered on to maintain a constant 5V or so across the collector-emitter junctions of the output transistors. Note that on L125 the lifter outputs are shared between all three power amplifiers for reasons of economy and space –...
  • Page 20 a Zobel network (sometimes called a Boucherot cell) to help compensate for inductive loads at high frequencies. The Class G Lifters are in two complimentary halves – TR600, TR601 and TR602 plus p-channel power MOSFET M601 for the positive half, and TR603, TR604 and TR605 plus n-channel power MOSFET M603 for the negative half.
  • Page 21 L129AY – Power Amp lower This contains the power amplifier electronics for the Left (L), Right (R), Surround Back Left (SBL) and Surround Back Right (SBR) channels. It also contains housekeeping logic for the amplifier protection system and power drive circuits for the protection relays and cooling fans. The power amplifiers are essentially identical to those in L125, except that the lifter circuits are only shared between pairs of power amplifiers (L and SBL, R and SBR respectively) rather than all three channels in L125.
  • Page 22 The micro is an Atmel AT91SAM7S32 (IC101) which must be initially programmed via the Atmel/Segger debugger via CON101. Subsequently, the micro can be reprogrammed from the PW338 using the Arcam upgrader utility over RS232. The bootloader should never need to be updated and as such will not be included in the standard upgrading application.
  • Page 23 L127AY Front Input This PCB handles the auxiliary input & headphone output. SKT101 carries the headphone output from L117 (Analogue output). There is also a switch to sense the headphones being inserted. The pullup resistor for this is on L122, so if L127 PCB is not fitted or the cable not fitted, the unit will sense the headphones are permanently inserted.
  • Page 24 Power for the DSPs comes from two regulators 3V3 (REG300), further regulated to 1V2 (REG301). Both are heatsinked.
