1.1 cables and connections

PPlease do not modify the standard interconnect cables supplied with your Naim
equipment. This is important for safety as well as performance. One end of each
cable is marked with a band to establish its correct orientation. The band always
marks the end that connects to the signal source.

Loudspeaker leads are also very important. Naim loudspeaker cable is correct for
your system and your dealer will make up leads to suit your equipment
installation. The leads should each be at least 3.5 metres long and of equal
length. The recommended maximum is 20 metres. Loudspeaker leads are, like
interconnect leads, directional, and should be connected so that the printed
arrow points towards the speakers. Using alternative loudspeaker cable will
degrade performance, and may even damage your amplifier. An exception to
these loudspeaker cable constraints is the nap 6-50 multi-room power
amplifier. The nap 6-50 is designed to be tolerant of both a wide variety of cable
types, and cable runs well in excess of 20m. The loudspeaker connectors supplied
with all Naim amplifiers and loudspeakers have been specifically designed to
make a robust mechanical connection. It is essential that these are used in order
to comply with current European safety regulations.

All the plugs and sockets supplied with your Naim equipment have been chosen
because they make the best possible connection for their purpose. A poor
contact will degrade the signal substantially and plugs and sockets should look
clean and free from corrosion. The easiest way to clean them is to switch off the
equipment, pull the plugs out of their sockets, and push them back in again.
Special contact cleaners and contact enhancers should not be used as they tend
to deposit a film which is very difficult to remove and may degrade the sound.

2.0 Getting Started

2.1 switching on and off

Source components and power supplies for cd players, tuners, preamplifiers and crossovers
should be switched on before switching on the amplifier(s). Always switch the amplifier(s)
off and wait about a minute for its power supply capacitors to discharge before
connecting or disconnecting any leads. Always use the power switch on the product rather
than a mains outlet switch.

2.2 running in

Your Naim equipment will take a considerable time to run-in before it performs at its best.
The duration varies, but under some conditions you will find that the sound continues to
improve for as much as five weeks. Better and more consistent performance will be
achieved if the system is left switched on for long periods. It is worth remembering
however that all electronic equipment can be damaged by lightning. Please read the
warnings section.

2.3 mains supply

Where fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail
after a period of use.

A hi-fi system usually shares a mains circuit with other household equipment some of
which can cause distortion of the mains waveform. In some Naim equipment such
distortion can lead to a mechanical hum from the transformers. The hum is not
transmitted through the speakers and has no effect on the performance of the system but
is purely local to the transformer itself. A separate fused mains circuit (like that reserved
for electric cookers) may reduce transformer hum. Such a circuit (ideally with a 30 or 45
Amp rating) will also have a lower impedance, supply cleaner power, and consequently
improve system performance.

Do not wire voltage dependent resistors or noise suppressors into mains plugs. They
degrade the mains supply and the sound.

2.4 siting the equipment

Power supplies and amplifiers should be located a reasonable distance away from other
equipment. This separation will stop transformer radiation causing hum audible from the
loudspeakers. The minimum recommended distance is 300mm (12 inches), and that
allowed by the standard interconnect lead is the maximum.

Some Naim equipment is extremely heavy. Ensure than your equipment rack or table can
easily support the weight and is stable.

2.5 if you have a problem

Legal consumer protection varies from country to country. In most territories a dealer
must be prepared to take back any Naim equipment he has sold you if he cannot make it
work to your satisfaction in your own home. A problem may be due to a fault in any part
of the system or its installation so it is essential to make full use of your local dealer’s
diagnostic skills on site. Please contact your local distributor, or Naim at the address in
the back of this manual, if any difficulties cannot be resolved. Some Naim equipment is
made in special versions for different territories and this makes it impracticable to arrange
international guarantees. Please establish the guarantee arrangements with your own
dealer at the time of sale. We are always available to offer help and advice.

It is essential that repairs and updates are only carried out by an authorised Naim dealer,
or at the factory by Naim itself. Many components are made, tested or matched specially
for Naim and appropriate replacements are often unobtainable from non-specialist
sources.

3.0 Warnings

Naim equipment is designed to offer the finest sound quality that can be achieved,
avoiding compromise wherever possible. This can lead to circumstances that may be
unfamiliar. The material that follows contains advice specifically related to Naim
equipment as well as more general warnings about the use of domestic audio products.
Please read it carefully.

The transformers in Naim power amplifiers and power supplies may sometimes make a
mechanical noise caused by distortion of the mains waveform. Naim transformers are
large in size and have heavy gauge secondary windings making them relatively sensitive
to such distortion. A separate mains circuit for your hi-fi system may reduce the effect
while also giving an overall improvement in sound quality. It may be necessary however
to take account of mechanical transformer noise when siting your equipment.

In some circumstances, depending on where you live and the earthing arrangements in
your home, you may experience radio frequency interference. Controls on broadcasting in
some territories allow very high levels of radio frequency radiation and both the choice
and exact siting of equipment may be critical. If there is a known problem in your locality
it is advisable to arrange for a home demonstration before purchase to find out if Naim
equipment is likely to be affected. Susceptibility to radio frequency interference is related
to the wide internal bandwidth necessary for high sound quality. Systems incorporating
moving coil phono preamplifiers and active crossovers are more likely to suffer. A radio
frequency filter kit is available for some Naim equipment but sound quality will be
progressively compromised as more elements of the kit are fitted. In situations of extreme
radio interference Naim equipment may be unsuitable.

Your Naim hi-fi system can be damaged by lightning. Power amplifiers are particularly at
risk and should be turned off when there is risk of lightning strike. For complete protection
all mains plugs and any aerial cables should be disconnected when not in use.

Equipment must not be exposed to dripping or splashing and no objects filled with liquid,
such as vases, should be placed on the equipment.

important

In order to comply with current
European safety regulations it is
essential that the Naim loudspeaker
connectors supplied with amplifiers
and loudspeakers are used.

Do not under any circumstances
allow anyone to modify your Naim
equipment without first checking
with the factory, your dealer, or
your distributor. Unauthorised
modifications will invalidate your
guarantee.

For your own safety do not under
any circumstances open Naim
equipment without first
disconnecting the mains.

The following label is attached to
all mains powered equipment:

4.0 Connection

4.1 mains lead

As the colours of the wires in the mains lead of this apparatus may not correspond with
the coloured markings identifying the terminals in your plug proceed as follows:

The wire which is coloured GREEN-AND-YELLOW must be connected to the terminal in
the plug which is marked by the letter E or by the safety earth symbol or coloured green
or green-and-yellow.

The wire which is coloured BLUE must be connected to the terminal in the plug which is
marked with the letter N or coloured black.

The wire which is coloured BROWN must be connected to the terminal in the plug which
is marked with the letter L or coloured red.

4.2 non-rewireable mains plugs

If a non-rewireable plug is cut from a mains lead (for whatever purpose) the plug MUST
be disposed of in a way to render it totally unusable. Considerable shock hazard exists if
the cut-off plug is inserted into a mains outlet.

4.3 fuse carrier

Should the plug fuse carrier be damaged or lost, the correct replacement must be obtained
from your dealer or from Naim direct. Do not use the plug until the fuse carrier is replaced.

4.4 plug fuses

Replace only with ASTA or BS 1362 approved fuses.

note

CDS Player Operation

There are six buttons on the right hand side of the cds player front panel. Press to activate. Several of
these buttons operate differently depending on whether the player is in load condition (after a disc
has been loaded, but before the play button has been pressed). The player returns automatically to
load condition either at the end of the disc, or at the end of the last track of a programme, or when
the stop button is pressed or when the lid is opened and closed.

display

In load condition makes the player display alternate between showing:

(a) the total number of tracks, (b) total time and (c) display off.

In play condition makes the player display alternate between showing

(a) the number (and index number) of the track being played, (b) the time it has been played and
(c) display off.

previous

In load condition searches the table of contents backwards, either one track at a time, or sequentially if
you hold the button depressed. Then press PLAY to play the track chosen. In play condition mutes while
searching the table of contents backwards, and then plays the track chosen without further command.

next

The next function operates in the same way as the previous function, but moving forwards through
the disc instead of backwards.

pause

Mutes the sound, leaving the laser arm paused in its current position (and the disc still rotating).
Pressing a second time turns the sound back on. In between, you may choose to use the previous or
next functions to select a different track. To play the chosen track you will then need to undo the
pause with a second press of the button.

c d s

stop

Stops the disc rotating, returns the laser to its inner position, and resets the player to load condition.

play

Causes the player to enter play condition. The loaded disc will start to play, beginning with track one,
unless another track has been selected. If you press play while a track is already playing, the track will
be re-started. When an HDCD encoded compact disc is loaded the CDS automatically recognises it and
decodes the relevant information. The display will read HDCD for a few seconds after the play button
is pressed (from load condition).

These functions are duplicated on the remote control which also provides many additional facilities.
For further information please refer to the instructions on page 18.

On the far right of the display are three indicators.

track

When lit, the display shows the total number of tracks(in load mode) or track number selected (in play
mode).

time

When lit, the display shows total time (in load condition) or elapsed time of track being played (in play
condition). To the right of these indicators is an alphanumeric display for track and index numbers, OR
time in minutes and seconds, OR various system messages (eg: play, err etc). The full stop on the right
of the window comes on when the player receives a signal from the remote control.

repeat

Shows (when lit) that repeat has been selected from the remote control.

program

Shows (when lit) that a program has been stored. For further information please refer to the remote
instructions on page 18.
