    CH C1 Digital to Analog Controller using the proprietary high definition CH Link interface. Optional boards allow to extend the functionality of the base version of the D1 SACD/CD drive. By adding two monaural ANALOG_OUT boards or a stereo ANALOG_OUT board the D1 becomes an integrated stereo SACD/CD player. Seamless migration to multi-channel is achieved by adding further output boards for the additional surround channels.

    1.2 Mechanical construction The D1 SACD/CD unit is assembled from high-quality aluminum and steel elements with no visible screws on the front, top and side panels. The base of the unit is made of a heavy steel plate whereas the front panel, the side panels and the top cover are machined from aluminum.

    The SYNC_IO board provides advanced clock synchronization options for D1 when used with an external clock generator such as the CH Precision T1 10MHz time reference or matching CH DAC (C1). It includes a clock input on BNC connector with selectable 75 Ohm or high input impedance.

  • Page 11: Power Supply

    stability external clock source is available but both C1 and D1 are equipped with a SYNC_IO board, the optimal configuration is to set the C1 as the clock master (C1 clock source: INTERNAL), and D1 as the clock slave (D1 clock source: SYNCHRO BNC 75). In that case, connect one of C1's BNC clock out to D1's clock in configured as a 75 Ohm input with a 75 Ohm BNC-terminated cable.

    2.5 Transport and packaging The D1 SACD/CD unit must always be stored in its original packaging for transportation. Doing so will ensure optimal level of protection of your unit. Therefore, keep all the packaging material in a dry and clean place for future use.

  • Page 14: Cleaning

    2.7 Maintenance and service The D1 SACD/CD unit contains no user serviceable parts. Do not try to open, modify or repair your D1 by yourself. This will void any warranty. Your D1 SACD/CD player must be checked by a qualified technician in any of the following cases: The unit is not functioning properly •...

  • Page 15: Installation

    3.1 Unpacking Unpack the D1 SACD/CD unit and store the packaging for future transportation. Be careful when lifting the D1 as the unit is heavy (over 30kg). Get someone to help you if necessary. When unpacking and installing the D1, take care not to damage the high quality surface treatments.
  • Page 16 If no CH Precision unit is to be stacked on top of the D1, screw the four top covers back. Otherwise, screw the four polymer stacking caps instead, and gently lay down the unit to be stacked on top of it. Be very careful that both units are perfectly aligned in order not to scratch the D1's top plate with the other unit's feet.

    3.3 Connections This section provides information about how to connect your D1 SACD/CD unit to your system. As the D1 is a modular design with different optional boards, the description applies to the example configuration presented below. If your options do not match the example or you don't feel secure with the connections to be applied to your configuration, please contact your authorized dealer for assistance.

For more information on unit firmware update, please refer to the corresponding section of this manual. 3.3.1.2 Ethernet port The Ethernet port on the CONTROL board is dedicated to network based control of the unit.

  • Page 20: Standard Digital Outputs

    3.3.2.1 Standard digital outputs Each DIGITAL_OUT board provides three standard digital outputs: AES-EBU (carrying consumer encoding), Coaxial (S/PDIF) and Optical (TOSLINK). Digital output is fixed at 16bits/44.1kHz on all standard outputs. If an SACD is played in the D1, the DSD stream is down converted to 16bits/44.1kHz on the standard digital outputs.

  • Page 23: Operation

    Operation The D1 SACD/CD unit is operated either from the front panel or from the IR remote control. Feedback to the user is provided by a high-definition AMOLED display with customizable colors. Setup operations are exclusively handled from the front panel.

  • Page 24: Operating Modes

    4.2 Operating modes The D1 SACD/CD unit has two main operating modes: Normal mode and Menu mode. Normal mode is used to access standard playback controls whereas Menu mode is used to configure the unit. The D1 also includes Shortcuts for quick access to selected Menu mode items.

  • Page 25: Normal Mode

    4.2.1 Normal mode Normal mode is used for SACD/CD playback control. When powered-on, the D1 SACD/CD unit starts in Normal mode. The display looks as follows: Normal mode display elements (1) Disc layer selection for SACD (indicates 6ch if multi-channel layer is selected and player is equipped for multi-channel or DM if the multi-channel layer is read but the player output is stereo only) (2) Time display mode.

  • Page 26: Shortcuts

    4.2.2 Shortcuts The D1 SACD/CD unit is configured by a set of menus as described in the next sections. To allow quick access to the most frequently used configuration menu items, the D1 offers the concept of Shortcuts. Shortcuts are fully programmable and the user may choose any configuration parameter as a Shortcut.

    4.5 Advanced clocking When connected to the CH C1 DAC, different clocking scheme can be used, depending on the D1 and C1 options. Some are simply not working at all (no sound will come out of your DAC, e.g. because at least one unit doesn't lock its internal clock to the configured clock source), some others will work for some time before muting (e.g.
