Arcam rDac Service manual Andy Moore ‐ issue 1

Overview The rDac is a D to A convertor featuring Optical / Coaxial and USB inputs and utilizes a simple push button to cycle between the input option – when locked on to data the LED in front of the relevant source will light Green and audio should be present if the LED is RED in color the input is not locked onto relevant data. Compatible formats include. All PCM 2 channel Input / bit depth 32kHz 44.1kHz 48kHz 88.2kHz 96kHz 176kHz 192kHz USB 16 & 24 Bit Yes Yes Yes Yes Yes No No Optical 16 & 24 Bit Yes Yes No No No No No Coaxial 16 & 24 Bit Yes Yes Yes Yes Yes Yes (1) Yes (1) Wireless 16 Bit No Yes No No No No No (1) Source may not be capable of resolution Power supply circuit page 5 A external 6v 600ma D.C power supply is used to supply the required power to the Connector at location CON400 this is then switched by the rear panel mounted power switch at location SW400, D400 is used for PSU monitor by associated circuitry formed by IC105 and IC104, D401 is used to prevent reverse bias of the PSU, the supply is then filtered by the network of L400 and C400 to form the main PSU source of +6v D.C. The rDac features 7 separate regulated powers supplies details appear in the table below Regulator locations Voltage (d.c) Components associated REG400 +5v Kleer option, optical input rec, LED array via IC102 REG401 +3V3 IC 100, 103, 104, 108, 107, 200, 201, 202, 203, 204, 205, 206, 301 mute circuit REG402 +3V SPDIF receiver REG403 +5v Output stage +5v REG404 +3v3 Oscillator REG405 +5v DAC IC400 ‐5v Output stage ‐5v IC107 +1.8 Main micro core voltage

Main micro circuit page 2 The main micro at location IC107 (on the diagram this is split into two area these are micro power and config + Micro I/O) we will deal with Micro power and config 1st. Micro power and config Two separate power supplies are required by the AT91SAM these are taken from 3V3 and 1V8 for the processor core – the micro is programmed with bespoke Arcam code the oscillator for the micro is at X101 and runs at 4MHz the TDI TDO TCK TMS ERASE NRST pins are for development Debug use and the connecter at location CON103 is not fitted to production items Micro I/O Pin descriptions Pin name Description SPDIF INT Interrupt flag from the SPDIF receiver Source To source select TACT switch Mute RLY Control of mute relay via TR100 DAC MUTE DAC MUTE signal to Pin 25 of Wolfson DAC at location IC301 ENABLE KLEER To MUX at location IC205A ENABLE SPDIF To MUX at location IC202A SERIAL UC to KLEER Serial control to KLEER wireless option SERIAL KLEER to UC Serial data from KLEER to UC SCL To EEprom at location IC108 / DAC at location IC301 / USB receiver at IC103 SDA To EEprom at location IC108 / DAC at location IC301 / USB receiver at IC103 Enable LEDS LEDs on control LED 0 Binary select for LED control via 3 – 8 line decoder at location IC102 LED 1 Binary select for LED control via 3 – 8 line decoder at location IC102 LED 3 Binary select for LED control via 3 – 8 line decoder at location IC102

Input Stages and switching Circuit pages 2 and 3 The inputs are split into two groups with the Wolfson SPDIF receiver at location IC201 dealing with Optical and Coaxial selection whilst the MUX at locations IC202A IC202B and IC205A switch between SPDIF (opt or coax) and USB or KLEER under control from main micro. SPDIF input The Wolfson WM8805 SPDIF receiver supplies data in a format of Data , LRCLK, BCLK and MLCK, the output of IC201 runs directly to the DAC via the MUX at location IC202A with exception of the MCLK this take a path thru IC203 as part of the MCLK MUX between USB / KLEER and SPDIF MCLK’s. USB input The USB data arrives at CON100 before traveling to the USB streaming control chip at location IC103 via the ESD protection Chip at location IC101 the chip is loaded with the DCS asynchronous/isochronous input system from IC100 at boot up. IC103 has it own MCLK source at location IC204 another WM8805 this time used as an adaptive clock source the output is buffered by IC203C The Data , LRCLK, BCLK are switched to the DAC via IC202B with the MCLK coming via IC203. DAC and Audio Stages circuit page 4 The Wolfson 8741 DAC can be found at location IC301 and takes its supplies from 3V3D and 5VDAC, data enters the chip on pins 1 – 5 and should be seen as below. Analogue audio leaves the DAC as balanced pairs on pins 16 / 17 (left) and 12 / 13 (right) audio then travels thru and filter network enters the Op‐amp at location IC300 a/b (L/R) and then onto IC302 a/b (L/R) output muting is twofold with both DAC mute (transistor mute) and full mute (relay) the DAC mute is provided by transistors TR302 and TR305 switching the audio down to 0v this under the control of the DAC MUTE line from IC107, the relay mute is provided by RLY300 and triggered from 2 lines one being the power detect sourced from D400 at power In – under low power the relay will close at 5.3v D.C and is flipped by IC105 in combination with IC104 the output of IC104 is low to mute the relay is switched by TR300.
