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.
