12 CD5 XS In Use
12.1 Signal Output Selection
The CD5 XS 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 CD5 XS must be switched off before the output selection
switch is operated. Ensure the correct cables are connected
before switching the
CD5 XS back on.
Note: Your local retailer will be able to offer advice on digital
output cables.
12.2 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 CD5 XS
will automatically recognise and decode it. The display will read
HDCD for a few seconds after play is pressed.
12.3 Power Supply Upgrade
The CD5 XS analogue output stage can be upgraded through
the addition of an external Flatcap or Hi-Cap Power Supply.
The external supply works with the internal power supply of
the CD5 XS to offer both a greater number of separate supplies
and more sophisticated voltage regulation. The Power Supply
is connected to the CD5 XS via a five pin DIN cable. Switch off
both the power supply and CD5 XS when making connections.
Remove the link plug and connect the supply cable ensuring
that the connectors are securely attached. Switch on both the
CD5 XS and the power supply from their respective power
buttons.
12.4 Player Maintenance
It is important for reliable operation of the CD5 XS 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.
