7 CDX2 Introduction and Installation
The CDX2 CD Player can be operated either from its internal power supply or, for improved
performance, from an external Naim CD 555PS or XPS Power Supply. Connection of the XPS
Power Supply is illustrated in Diagram 11.2. CD player control and operation is described in
Sections 16, 17 and 18.
The CDX2 should be installed on a dedicated equipment stand intended for the purpose.
To improve sound quality the player has hard metallic feet which may blemish any delicate
surface on which it is placed. Do not stand the player directly on top of another item of Naim
Audio equipment. Care should be taken to ensure that the player is level.
The CDX2 is fitted with both analogue and S/PDIF digital output options selectable using a
rear panel switch.
A transit screw on the underside of the CDX2 should be removed before use and must be
replaced if the unit is to be moved or re-packed and shipped. The transit screw must not be
used in any other Naim product. Do not invert the player once the transit screw is removed.
The player (and external power supply if used) should be installed in its final location before
connecting cables or switching on. Ensure that power amplifiers are switched off and the
preamplifier volume is turned down before the player (or external power supply) is switched
on. The player power button is located on the rear panel. Power supply power buttons are
located on their front panels.
The player and power supply are heavy and care should be taken when lifting or moving
them. Make sure that the surface on which they are to be placed can support their weight.

Note: RCA phono and DIN output sockets should not be
connected simultaneously.
Note:
The power supply link plug should be fitted unless an
external upgrade power supply is in use.
Note
: The Remote Input is intended to accept external control
signals for multi-room applications. Contact your dealer or Naim
Audio directly for further information.
Note
: The optional RS232 Interface can provide external control
of the player in custom installations. Contact your dealer or
Naim Audio directly for further information.
