1 Technical highlights

CH products are proudly designed and manufactured in Switzerland by CH Precision Sàrl. Our engineers have put all their knowhow into bringing you the D1, a highest quality modular SACD/CD unit based on slot-in boards and USB flash-drive firmware update. In its base version the D1 is a pure digital two channel SACD/CD drive to be used with a high quality external Digital to Analog Converter (DAC). It includes a DIGITAL_OUT board and a CONTROL board. Highest quality playback is ensured when the D1 is paired to the matching 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. Up to four output boards can be placed in the D1. Any combination of stereo (L/R, Ls/Rs or C/Sub) digital (DIGITAL_OUT), main channels monaural (L + R) analog or stereo (L/R, Ls/Rs or C/Sub) analog (ANALOG_OUT) output boards are allowed. Finally, the SYNC_IO optional board provides advanced clock synchronization capabilities for use with external clock generators or to enslave the D1 to the C1's master clock for zero-jitter connection.

1.1 SACD/CD drive (VMK-5)

The D1 SACD/CD unit is built around the high-quality Esoteric VMK-5 SACD/CD mechanism featuring VRDS-Neo disc clamping. The VRDS disc clamp covers the whole disc (not only its central part) ensuring vibration and error free digital data reading. CH has further improved the vibration immunity of the SACD/CD mechanism by mounting it on a heavy steel rails directly assembled to a massive steel base plate weighting over 15kg.

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 power supply is isolated from the audio section in its own compartment to avoid any contamination of the audio circuits by noise radiated from the supply. Pin assembly of all chassis elements provides smooth joints between elements while screws every 6cm ensures protection against electromagnetic interferences. First class mechanical and chemical surface treatments provide the luxury finish of the D1.

Four steel feet support the unit. Each feet ends with a elastomer ring to sit on delicate surfaces but is also equipped with a height adjustable steel spike to fine tune unit positioning. Horizontal adjustment is done with the provided screwdriver through the four adjustment shafts accessible from the top of the unit. In addition to providing convenient horizontal adjustment from the top of the unit, the shafts also serve as vibration evacuation channels for any stacked unit. Special shaft covers are provided to interface with the spikes of the stacked unit. Any vibration from the upper unit is transmitted by the shaft cover to the shaft and from the shaft to the lower unit feet or spike, forming a privileged path for vibrations evacuation.

1.3 Modular architecture and slot-in boards

The D1 benefits from a fully modular architecture. It features separated sections for power-supply, disc mechanism and related control, front panel, central host processor and slot-in boards. This modular architecture combined to the USB plug for all firmwares (MCU, DSP, and FPGA) update allows for easy servicing and upgrade should one section become faulty or obsolete.

The slot-in boards section consists in a vertically mounted mother board with optional boards plugged into it. Optional boards provide audio functionality and connectivity to other equipment. There are five types of slot-in boards:

• CONTROL board: provides a USB port for software upgrade and an Ethernet port for command

8 D1 User Manual Rev 3.0

• DIGITAL_OUT: provides two channels of digital audio output. Specific back panels for L/R, Ls/Rs or C/Sub channels

• Stereo ANALOG_OUT: provides two channels of analog audio output. Specific back panels for L/R, Ls/Rs or C/Sub

channels

• Monaural ANALOG_OUT: provides one fully balanced channel of analog audio output. Specific back panels for Left or Right channel

• SYNC_IO: provides advanced clock synchronization options (1 clock in, 2 clock out)

There are 6 slots in the D1. A CONTROL board is always installed inside the D1, leaving space for 5 optional boards. One of these slots is reserved for the SYNC_IO board. Note that optional boards MUST be installed by a qualified technician. Failure to do so will void any warranty. Following table shows the typical recommended configurations for D1:

1.3.1 Multi-channel support

True multi-channel SACD playback is achieved by means of optional boards. The Stereo versions of D1 are delivered with a single DIGITAL_OUT board and/or a single ANALOG_OUT board configured for L/R channels. They can be extended to multi-channel by simple addition of DIGITAL_OUT or ANALOG_OUT boards for the Ls/Rs and C/Sub channels. No other action is required as the D1 firmware will automatically sense the presence of the additional boards and enable true multi-channel reproduction.

When a D1 has multi-channel capability (either digital, analog or hybrid outputs), it will always select multi-channel DSD layer on SACDs whenever available. User can then manually change to another available layer (stereo DSD and/or CD layer) from a given disc.

Rev 3.0 D1 User Manual 9

When a D1 is purely stereo (either drive or player), it will first select stereo DSD layer on SACDs whenever available. User can then manually change to another available layer from a given disc, including a down-mixed version of the multichannel DSD layer if this layer exists.

Four channel configurations are not supported. Multiple output boards of the same type (DIGITAL_OUT or ANALOG_OUT) on any channel pair (L/R, Ls/Rs or C/Sub) are not supported.

1.3.2 Digital outputs and CH Link: DIGITAL_OUT board

The DIGITAL_OUT board provides digital output for an audio channel pair. Three different DIGITAL_OUT boards are available, corresponding to L/R, Ls/Rs and C/Sub channel pairs. Each DIGITAL_OUT board provides standard digital outputs in AES-EBU, Coaxial RCA (S/PDIF) and Optical TOSLINK (S/PDIF) formats as well as in the CH Link high-definition proprietary format. CH Link uses a dedicated connector to carry high resolution audio and control data over a single link between CH units. It supports both PCM (up to 768kHz, 32bits) and DSD. To comply with high definition digital content protection, DSD signals are cyphered when transported over CH Link from the D1. Standard digital outputs down-convert DSD signals to 16bits/44.1kHz PCM audio.

1.3.3 Stereo analog outputs: ANALOG_OUT board option

The ANALOG_OUT board provides analog line level output for two audio channels. Three different ANALOG_OUT boards are available, corresponding to L/R, Ls/Rs and C/Sub channel pairs. Each ANALOG_OUT board provides both balanced (on XLR connectors) and single-ended (on RCA connectors) outputs. Digital to analog conversion is handled by two WM8742 DACs (one per channel) combined with a discrete dual mono output stage. A choice of digital filters is available to the user. Filters for PCM and DSD audio can be selected independently.

1.3.4 Monaural analog outputs: Mono ANALOG_OUT board option

The monaural ANALOG_OUT board pair provides analog line level output for the two main audio channels (Left and Right). Each monaural ANALOG_OUT board provides both true balanced (on XLR connectors, with a dedicated analog output stage on each – warm and cold – point) and single-ended (on RCA connectors) outputs. Each board (i.e. each channel) has its own dedicated voltage regulators. Digital to analog conversion is handled by one WM8742 DAC on each board combined with a discrete dual mono output stage. A choice of digital filters is available to the user. Filters for PCM and DSD audio can be selected independently.

1.3.5 External clock synchronization: SYNC_IO board option

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. Supported input frequencies on this connector are all standard audio Wordclocks (44.1, 48, 88.2, 96, 176.4, 196, 352.8 and 384 kHz), audio Masterclocks (22.5792 and 24.576 MHz), DSD bitclock (2.8224 MHz) and atomicclock multiples (100 kHz and 10 MHz). When fed with an audio Wordclock, the D1's internal clock will lock its VCXO internal clock in frequency and in phase (phase accuracy of +/- 2.5 us), tracking below 0.1 Hz with 0.1 PPM corrections for optimal jitter rejection.

Two 75 Ohm Wordclock outputs completes the input/output capabilities of the SYNC_IO board.

When a T1 time reference clock generator is available, ultimate result is achieved when connecting both the C1 and the D1's clock input to two different clock outputs of the T1, and setting both C1 and D1's clock source to SYNCHRO BNC 75. If no ultra-high

10 D1 User Manual Rev 3.0

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.

1.4 Power supply

The power supply of the D1 is a linear supply with multiple independent local regulations. It is based on an oversized magnetically shielded toroidal mains transformer and includes a mains filter. A secondary (also toroidal) transformer is used as Standby transformer to ensure green Standby mode, meeting the latest energy saving regulations. Both transformers have static shields between primaries and secondaries. They are mounted on a separate steel plate which is isolated from the main base steel plate by silent blocks.

Discrete (power-transistor and op-amp based) ultra low noise regulators are used throughout the power supply and special care has been paid to the master clock power supply. The master clock benefits from its own dedicated supply, completely decoupled from the noisy digital and motor sections. This ensures an ultra-low jitter clock source for the whole system.

Input AC voltage to the power supply can be set to 100V, 115V or 230V AC depending on your local mains voltage.

1.4.1 Optional external power supply

The D1 is equipped with an external power supply input. This input is dedicated to the CH X1 external power supply. When the external power supply is connected, the internal power supply of the D1 is turned off (only the Standby transformer remains active). Turning the main internal transformer off ensures that no power supply induced noise or radiations are generated inside the D1 unit, thus permitting optimal operating conditions for the circuits. Moreover, the D1's internal voltage regulation stage are still active, cascaded with the X1's regulation stages, significantly lowering the noise floor.

If, after reading this manual, you feel unsure about how to make connections or how to operate the unit, please contact your authorized dealer.

2.4 Mains supply

Make sure to use 3 terminals (phase, neutral and earth) power cords with ground conductor. Make sure that the mains voltage selection of the unit matches your mains voltage.

Make sure your D1 SACD/CD unit is disconnected from AC wall power in the following cases:

• When making connections (it is also recommended to disconnect the rest of the system from AC wall power)

• When cleaning

• During thunder storms

• When unused for a long period

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.

To avoid any damage to the SACD/CD mechanism, an optical disc must be inserted into the drawer for transportation. We recommend a blank CD-R.

In addition, the transformer base plate must be secured for transportation to avoid excessive constraints on the silent blocks isolating the chassis from transformer vibrations. This is done by the insertion of a security screw on the bottom of the unit. Do not forget to install this screw for transportation and to remove it at installation of the unit in its new location.

Rev 3.0 D1 User Manual 13

Finally we recommend to remove the adjustment spikes and to put them into the D1 box for transportation. Indeed, vibrations during transport may cause the adjustment spikes to move from their fully retracted position. There is risk of scratching the installation base if the spikes are not fully retracted when installing the unit.

2.6 Cleaning

Use a soft, dry towel or cloth for cleaning. Never use any solvent or liquids as they may damage the surface treatment or penetrate inside the unit.

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

• The mains cable or the power cord receptacle is damaged

• The unit has been dropped to the floor or presents external damage

• The D1 SACD/CD player has been exposed to liquids (such as rain) or unknown substances

3 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.

3.1.1 Removing the security screw

The transformer base plate must be secured during transportation to avoid damage to the isolating silent blocks. The security screw is located at the bottom of the unit. To remove the security screw, tilt the unit on its side and unscrew. Do not tilt the unit on the front or back panels as this may damage the user control knob or the connectors.

Security screw location

(1) Security screw. Must be mounted for transport and removed at installation

3.2 Unit positioning

When delivered from factory, the D1 SACD/CD unit's four feet sit on elastomer rings, ensuring both scratch-protection for the base on which the unit sits, as well as safe anti-slipping unit positioning.

But a more advanced vibration-channeling mechanical coupling can be implemented, thanks to the steel spikes and the polymer support discs provided with the D1. To use this optimal coupling, simply go through the following steps:

1. Place the D1 unit on a stable base at its approximate final position, for instance in your preferred audio rack. Make sure

cooling air is able to freely flow around the unit.

2. Gently lift the unit's corners and insert a support disc under each foot. The foot's elastomer ring should disappear in the

support disc's groove when properly placed. Carefully check all four feet perfectly fit in each support disc before pursuing any further. The unit should stably rest on its feet at that point.

Rev 3.0 D1 User Manual 15

3. Unscrew the four top covers from the D1's shafts with the provided suction cup. Be careful not to scratch their delicate

finish.

4. Insert the adjustment spikes into each adjustment shaft.

5. Softly screw clockwise each adjustment spikes into the shaft with the provided screwdriver, until any resistance is felt (just

before the unit's corner starts to lift).

6. Then screw clockwise each spike by the same amount (for instance two full turns).

7. If the base is flat, the unit should be stable and horizontal. If not, correct the unit's stability and horizontality by turning

clockwise or anti-clockwise the required spikes.

8. 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. Repeat steps 3 to 8.

Each D1 unit provides 5 expansion slots supporting any combination of the following optional boards (note that one slot is dedicated to the SYNC_IO board):

• Stereo DIGITAL_OUT boards for L/R, Ls/Rs or C/Sub channels

• Stereo ANALOG_OUT boards for L/R, Ls/Rs or C/Sub channels

• Monaural ANALOG_OUT Left and Right boards (must be used together as a pair)

• SYNC_IO board for external clock synchronization

Note that only one SYNC_IO board is allowed. Each pair of channels (L/R, Ls/Rs or C/Sub) can support a DIGITAL_OUT and/or an ANALOG_OUT board. Optional output boards can be placed in any slot. Installation of optional boards must be done by a qualified technician only. Do not attempt to install any optional board by yourself as this would void the unit's warranty.

3.3.1 CONTROL board

The CONTROL board is factory installed into the D1. It provides a USB port for software updates and an Ethernet port for controlling the unit over a network. Following drawing shows the layout of the back panel of the CONTROL board:

18 D1 User Manual Rev 3.0

CONTROL board back panel layout

3.3.1.1 USB port

The USB port on the CONTROL board is dedicated to the firmware update of the D1 unit. Do not use it for any other purpose. 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. This functionality is currently not implemented, thus leave the Ethernet port unconnected. A future D1 firmware release will provide this functionality.

3.3.2 DIGITAL_OUT boards

DIGITAL_OUT boards provide digital audio output capabilities. Additional DIGITAL_OUT boards for Ls/Rs and C/Sub channels can be added to the default factory installed DIGITAL_OUT L/R into D1 for full digital high-definition multi-channel support. DIGITAL_OUT boards provide both standard (AES-EBU, Coaxial and Optical) digital audio outputs and a proprietary (CH Link) highdefinition digital audio interface. Following drawing shows the layout of the DIGITAL_OUT board connectors and naming for the different channel pairs:

DIGITAL_OUT boards back panel layout for L/R, Ls/Rs and C/Sub channels

Rev 3.0 D1 User Manual 19

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. When a CD is played, the data from the disc is directly transferred to the standard digital outputs.

3.3.2.2 CH Link digital audio interface

Each DIGITAL_OUT board includes a CH Link proprietary digital audio interface. This interface carries both complete audio stream and control information. Use this link as the preferred interface when connecting your D1 to other CH units such as C1 converters.

The proprietary CH Link digital audio interface allows for high definition uncompressed digital audio transfer and supports both DSD and PCM (up to 705.6 / 768 kHz). For digital content protection reasons, the CH Link interface cyphers the native DSD stream from SACD when transferring such data.

3.3.3 Stereo ANALOG_OUT boards

ANALOG_OUT boards provide analog audio output capabilities. ANALOG_OUT boards for L/R, Ls/Rs and C/Sub channel pairs can be installed into D1 for analog stereo or multi-channel support. DIGITAL_OUT, stereo ANALOG_OUT and monaural ANALOG_OUT boards can be combined, providing for instance digital output on the main (L/R) channels and analog out on Ls/Rs and C/Sub channels. Stereo ANALOG_OUT boards provide both balanced (XLR) and single-ended (RCA) analog audio outputs. Following drawing shows the layout of the Stereo ANALOG_OUT board connectors and naming for the different channel pairs:

Stereo ANALOG_OUT boards back panel layout for L/R, Ls/Rs and C/Sub channels

3.3.4 Monaural main ANALOG_OUT boards

ANALOG_OUT boards provide analog audio output capabilities. Monaural ANALOG_OUT board pairs for Left and Right channels can be installed into D1 for analog support on main channels. DIGITAL_OUT, stereo ANALOG_OUT and monaural ANALOG_OUT boards can be combined, providing for instance monaural analog output on Left and on Right channels, and stereo analog output on Ls/Rs and C/Sub channels. Monaural ANALOG_OUT boards provide true fully-balanced (XLR), single-ended 75 Ohm (RCA) and single-ended 50 Ohm (BNC) analog audio outputs. Following drawing shows the layout of the Monaural ANALOG_OUT board connectors and naming:

20 D1 User Manual Rev 3.0

Monaural ANALOG_OUT board pair

3.3.5 SYNC_IO board

The SYNC_IO board is an optional clock synchronization board to be used with an external clock generator or together with other CH products, such as the C1 Digital to Analog Controller. The board provides one clock input and two clock output on BNC connectors. The VCXO digital PLL of the D1 is capable of frequency and phase locking. The frequency is tracked below 0.1 Hz with

0.1 PPM adjustments for optimal jitter rejection. When fed with an audio Wordclock, the D1's internal clock will always keep a phase accuracy below 2.5 us (equivalent to sub-millimeter position accuracy), thus enabling phase perfect match in a multichannel configuration. Following diagram shows the layout of the back panel of the SYNC_IO board:

SYNC_IO board back panel layout

3.3.5.1 BNC clock input

The SYNC_IO board provides a BNC clock input that can be configured as 75 Ohm input impedance or high input impedance through the D1's menu. Supported input frequencies on this connector are all standard audio Wordclocks (44.1, 48, 88.2, 96,

176.4 and 196 kHz), audio Masterclocks (22.5792 and 24.576 MHz), DSD bitclock (2.8224 MHz) and atomic-clock multiples (100 kHz and 10 MHz). Use this connector to synchronize your D1 unit to an external clock source (atomic clock generator or external DAC such as CH C1).

3.3.5.2 BNC clock outputs

Two 75 Ohm output clock connectors are also provided on the SYNC_IO board. Use one of these connectors to synchronize an external device to your D1. Output clock is either a buffered version of input clock (if D1 is synchronized to it input clock), or

Rev 3.0 D1 User Manual 21

current audio Wordclock (if D1 is clocked by its internal high precision oscillator).

3.3.6 Power cord receptacle and voltage selection

Make sure that the voltage selection is set to the correct value with respect to the AC voltage in your location. Connect the power cord to the power cord receptacle and plug the power plug to an AC wall outlet only after all other connections have been made.

3.3.7 External power supply connector

The external power supply connector allows you to connect the X1 optional external power supply from CH. When the X1 is used, it completely replaces the D1's internal power supply, resulting in minimized noise and enhanced audio quality. Note that only the (small) standby transformer of the D1 remains active in this case to ensure the D1's wake up functionality.

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. Indicates TOTAL if time information is relative to the whole disc (3) Mute indication. If the 7 symbol is present, the output is muted (4) Repeat indication. If the symbol : is present, repeat mode is engaged (5) Repeat type. If repeat is for the whole disc, the indication ALL is activated (6) Current time. Negative time indicates remaining time (either for track or for disc) (7) Polarity (phase) indication. If the H symbol is present, polarity is reversed (8) External power supply indication. When an external power supply is connected and engaged, < symbol is displayed and internal power supply is

turned off

(9) Clock source indication (10) Playing status indication (11) Lock indication (J or K). Tells if the unit is locked to a clock source or not (12) Track number (13) Disc type (CD or SACD)

Displayed elements depend on the type of disc, installed optional boards and user settings. In the example above, the 7th track of a multi-channel SACD is played back on a unit supporting multi-channel output. Total elapsed time is 28min 34s, phase is inverted and the whole disc is repeated. The D1 powered through an external power supply and is locked to its internal clock but its outputs are muted. Displayed elements for other configurations and settings or when playing back a CD are similar.

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. There are up to 6 user programmable Shortcuts. To learn how to program individual Shortcuts, please refer to the SHORTCUTS menu item in the next section.

Shortcuts are accessed from Normal mode by a Normal Push [NP]. Additional Normal Push [NP] skips to the next Shortcut. The last Shortcut is always dedicated to entering the Menu mode (SETUP). On this last Shortcut, a Normal Push [NP] will return to Normal Mode and an External Rotate Right [E>>] (or Central Rotate Right [C>>]) will enter the Menu mode. The individual parameter for a given Shortcut is modified using External Rotate Left [<<E] (or Central Rotate Left [<<C]) and/or External Rotate Right [E>>] (or Central Rotate Right [C>>]). If there is no user action for 10s the unit will revert to Normal mode. Note that Shortcuts are dynamically loaded depending on the unit's state. For instance, the Shortcut for SEARCH will not appear if the unit is in STOP state as searching requires the disc to be playing.

the parent menu.

(2) A Parameter Value of '...' indicates that the menu items gives access to one or more further sub-menu(s). Further sub-menus have the same

structure as this example.

(3) This is the Parameter Value column. For each item in the Parameter column, the Parameter Value item on the same line indicates the current

value of the Parameter.

(4) This is the Parameter column. The currently active Parameter is highlighted. Use Central Rotate Left/Right [<<C]/[C>>] to navigate from

Parameter to Parameter.

(5) If the first or last item in the Parameter column is indicated by '...' it means that there are additional Parameters not displayed currently on-

screen. Use Central Rotate Left/Right [<<C]/[C>>] to navigate towards the '...' to make the corresponding Parameters appear on screen.

Once a terminal Parameter (e.g. a Parameter not giving access to a further sub-menu) is selected by External Rotate Right [E>>], the D1 displays the corresponding Parameter adjustment screen. Following example shows the AUDIO SETTINGS >> PHASE POLARITY Parameter adjustment screen. Other Parameters are similar but may show more (or less) choices for Parameter value. Once a Parameter is set to the desired value, a Normal Push [NP] saves the new Parameter Value and gets back to the parent level (save and exit). On the other hand, an External Rotate Left [<<E] gets back to the parent menu (in the case of this example: AUDIO SETTINGS), but possible modifications of the Parameter Value are discarded (exit without saving).
