9. CDX2 In Use

9.1 Signal Output Selection
The CDX2 can provide either analogue or S/PDIF format
digital signal output. The analogue output is carried by
either a single DIN socket or a pair of RCA phono sockets.
The digital output is carried by a single 75Ω BNC socket.
Digital and analogue outputs may not be used
simultaneously. Selection is achieved by using the rear panel
mounted switch. The CDX2 must be switched off before
the output selection switch is operated. Ensure the correct
cables are connected before switching the
CDX2 back on.
Note: Your local retailer will be able to offer advice on
digital output cables.
9.2 Disc Loading
To load a compact disc pull open the CD drawer using the
handle on the left hand side of the player. Place the disc
on the platter followed by the magnetic puck. Do not use
a puck from any other Naim CD player. Different Naim CD
players use dissimilar pucks.
Note: If an HDCD® encoded compact disc is loaded the
CDX2 will automatically recognise and decode it. The
display will temporarily read HDCD after play is selected.
Note: If a CD 555PS Power Supply is used to power a
CDX2 player use only power supply output Socket 1.
E7
Note: When used with an external power supply the CDX2
player must be disconnected from the mains. Disconnect
the player from the mains before connecting the power
supply.
9.3 Power Supply Upgrade
The CDX2 can be upgraded by the addition of a CD 555PS,
XPS or XP5 XS Power Supply. The external supply takes
over from the internal power supply of the CDX2 and offers
both a greater number of separate supplies and more
sophisticated voltage regulation.
The external supply is connected to the CDX2 via a heavy
duty "Burndy" cable. Switch off both the power supply and
CDX2 when making connections and remove the CDX2
mains cable. Remove the CDX2 link plug and connect the
Burndy cable ensuring that the connectors are securely
attached and their twist lock mechanisms are engaged.
Switch on the power supply from its front panel power
button. After a short while the CDX2 will function as normal.
9.4 Player Maintenance
It is important for reliable operation of the CDX2 to ensure
that the surfaces of the transport platter and the underside
of the puck are free of dust or debris which can prevent the
disc from sitting properly and cause it to slip.
To clean the transport platter, take a piece of Blu-Tack and
lightly apply it to the top surface of the magnetic metal hub,
picking up any material attached to it. Brush the plastic
outer edge lightly with your finger or a soft brush to ensure
that it is dust and particle free. Similarly, clean the puck
with Blu-Tack, to remove debris from its underside. Do not,
under any circumstances, use any solvents or fluids for the
cleaning process.
