  • Page 6: Technical Highlights

    CH Precision units. An X1 fitted with two regulation boards can be used to power two CH Precision devices simultaneously (such as a C1 controller, a D1 disc transport, a L1 line preamplifier or a P1 phonostage), with the advantage of dedicated transformers for analog and digital sections, and cascaded voltage regulation.
  • Page 7: Electrical Characteristics

    1.1 Electrical characteristics The X1 is a high grade linear power supply delivering the analog and digital DC power supplies required by a C1, D1, L1 and a P1 on high current capable M23 19-poles connector(s). Input AC voltage can be set to 100V, 115V or 230V AC to accommodate local mains supply.
  • Page 8: Mechanical Construction

    When the X1 external power supply is connected to a CH Precision device, the latter's internal power supply is turned off (only the standby transformer remains active, requiring its mains lead to remain plugged in). Turning the internal power supply off ensures that no power supply induced noise or radiations are generated inside that unit, thus permitting optimal operating conditions for the circuitry.
  • Page 9: Before Use

    Please store the packaging for future transportation. Check your X1 external power supply for apparent damages. In case of damage, please contact your authorized dealer. If your X1 is still very cold following transport, please let it warm up to room temperature before powering it up (in order to avoid condensation inside the unit).

    2.7 Maintenance and service The X1 external power supply contains no user serviceable parts. Do not try to open, modify or repair your X1 yourself. This will void any warranty. Your X1 must be checked by a qualified technician in any of the following cases: The unit is not functioning properly •...
  • Page 12: Installation

    If no CH Precision unit is to be stacked on top of the X1, 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 X1's top plate with the other unit's feet.
  • Page 13: Connections

    This section provides information on how to connect your X1 external power supply to your system. As the X1 can be configured to power one or two CH Precision devices, it can be fitted with a single or two POWER SOURCE boards (the picture below shows an X1 with two POWER SOURCE boards).

    3.3.2 POWER SOURCE board As an X1 can be used to power one or two CH Precision units, it can be fitted with one or two Power source boards. Each board has its own set of discrete regulators for analog and digital voltage rails. The following drawing shows the layout of the back panel of...
  • Page 16: Power Cord Receptacle And Voltage Selection

    Make sure that the voltage selection is set to the correct value with respect to the AC mains voltage in your location. Connect the power cord to the power cord receptacle and plug the power plug to an AC wall socket only after all the other connections were made. X1 User Manual Rev 2.1...
  • Page 17: Operation

    The standby LED lights up when the unit is in standby, i.e. when no connected CH Precision unit is being powered. It normally turns off when the X1 is on, i.e. when at least one connected CH Precision unit is being powered. The LED can also be programmed to remain on during operation.
  • Page 18: Configuration

    Each button has two different functions: a main function and an alternate function. The main function is called if the button is pushed while the X1 is in standby or on (i.e. powering a CH unit).
  • Page 19: Firmware Update

    Make sure this file is present at the root of your USB stick, and that only one version of this file is present. If multiple versions of the same unit's firmware are present at the root of the USB stick, it can not be guaranteed which one will be loaded as the new X1 firmware.
