SAFETY INSTRUCTIONS

• 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 retailer, or your distributor.
• Unauthorised modifications will invalidate your guarantee.
• Equipment must not be exposed to dripping or splashing and no objects filled with liquid, such as vases, should be placed on the equipment.
• For your own safety do not under any circumstances open Naim equipment without first disconnecting it from the mains.
• Warning: an apparatus with CLASS I construction shall be connected to a mains socket outlet with a protective earthing connection.
• Where the mains plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable. To disconnect the equipment from the mains remove the mains plug from the mains outlet.
• The following label is attached to all mains powered equipment:

NOTE
This equipment has been tested and found to comply with the relevant EMC and Safety Standards, and, where applicable, also complies with the limits for a class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult your Naim retailer or an experienced radio/TV technician for help.

Introduction

Naim Audio products are conceived with performance as the top priority. Careful installation will help ensure that their full potential is achieved. This manual covers the CD555, CDX2, CD5 XS and CD5si CD players and their associated or upgrade power supplies. It begins with some general installation notes and statutory safety warnings. Product specific information begins in Section 4.

Connections
It is important for both safety and performance that the standard cables supplied are not modified.

Interconnect Cables
If options are available with your equipment and installation, DIN interconnect sockets should be used in preference to RCA Phono sockets. One end of each Naim interconnect cable is marked with a band to establish its correct orientation. The band denotes the end that connects to the signal source. Interconnect plugs and sockets should be kept 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. Contact cleaners and “enhancers” should not be used as the film they deposit may degrade the sound.

Mains Power

Where fused plugs are used 13 amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. Do not wire voltage dependent resistors or noise suppressors into mains plugs. They degrade the mains supply and the sound.

Mains Plug Wiring

In some territories a mains plug may need to be fitted to the supplied mains lead. As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in the plug proceed as follows:
The wire coloured GREEN-AND-YELLOW must be connected to the terminal in the plug marked by the letter E or by the safety earth symbol or coloured GREEN or GREEN and YELLOW.
The wire coloured BLUE must be connected to the terminal in the plug marked with the letter N or coloured BLACK.
The wire coloured BROWN must be connected to the terminal in the plug marked with the letter L or coloured RED.

Equipment Fuses
Mains powered Naim Audio equipment is fitted with a mains fuse on the rear panel adjacent to the mains input socket. Replace it if necessary only with the spare fuse supplied or with an identical fuse. Repeated failure of the fuse points to a fault that should be investigated by your retailer or Naim itself.

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

Mains Circuits and Cables

• A hi-fi system usually shares a mains circuit with other household equipment some of which can cause distortion of the mains waveform. This distortion can in turn lead to mechanical hum from mains transformers. Some Naim transformers are large in size, making them relatively sensitive to such distortion, and it may be necessary to take account of transformer hum when siting your equipment.
• Transformer hum is not transmitted through the speakers and has no effect on the performance of the system; however, a separate mains circuit may reduce it. Such a circuit (ideally with a 30 or 45 Amp rating) will also generally improve system performance. Advice on the installation of a separate mains circuit should be sought from a qualified electrician.
• Only use the mains leads and plugs supplied or alternative Naim Audio items.

General Installation

Naim equipment is designed to offer the finest performance possible avoiding compromise wherever practical. This can lead to circumstances that may be unfamiliar. The notes that follow contain advice specifically related to Naim equipment as well as more general warnings about the use of domestic audio products. Please read them carefully.

Siting The Equipment
In order to reduce the risk of hum audible from the loudspeakers, power supplies and power amplifiers should be located a reasonable distance away from other equipment. The maximum separation distance for connected equipment is that allowed by the standard interconnect lead. Some Naim equipment is extremely heavy. Check the weight of the equipment prior to lifting and if necessary use more than one person so that it can be moved safely. Ensure that your equipment rack or table can easily support the weight and is stable. Some speakers and stands are intended to be used with floor spikes fitted. Care should be taken when siting and moving them to avoid personal injury or damage to cables and surfaces. Floor protectors are available from your local dealer or distributor to protect non carpeted floors.

Switching On

• Source components and power supplies should be switched on before the power amplifiers. Always switch amplifiers off and wait a minute before connecting or disconnecting any leads. Always use the power switch on the product rather than a mains outlet switch.
• A “thump” may be heard from the loudspeakers as power amplifiers are switched on. This is normal, will not cause any loudspeaker damage and does not point to any fault or problem. A mild “pop” may also be heard shortly after equipment is switched off.

Running In
Naim equipment takes a considerable time to run in before it performs at its best. The duration varies, but under some conditions the sound may continue to improve for over a month. Better and more consistent performance will be achieved if the system is left switched on for long periods. It is worth remembering however that equipment left connected to the mains can be damaged by lightning.

Radio Interference
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. Susceptibility to radio frequency interference is related to the wide internal bandwidth necessary for high sound quality. 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.

Lightning Precautions
Your Naim hi-fi system can be damaged by lightning and should be turned off and disconnected from the mains when there is risk of lightning strike. For complete protection all mains plugs and any aerial cables should be disconnected when not in use.

Problems?
Consumer protection varies from country to country. In most territories a retailer must be prepared to take back any equipment he has sold if it cannot be made to work satisfactorily. A problem may be due to a fault in the system or its installation so it is essential to make full use of your dealer’s diagnostic skills. Please contact your local distributor, or Naim Audio directly, 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 local guarantee arrangements with your retailer. Contact Naim Audio directly for help and advice if necessary.

Service and Updates
It is essential that repairs and updates are only carried out by an authorised Naim retailer or at the factory by Naim itself. Many components are custom made, tested or matched and appropriate replacements are often unobtainable from other sources. Direct contact to Naim for service or update information should be made initially through Customer Services:

• fwd Fast forwards the cd.
• rev Fast reverses the cd.
• rpt Repeats the cd or programmed tracks.
• pause Pauses the cd.
• Soft Key s keys operate, in CD mode (selected by the System Component Keys), as follows:
• numeric : Directly selects tracks or, with the prog key, selects tracks for play order programming.
• prog : Confirms CD track play order selections.
• disp: Scrolls through the display options of track, time and display off.

Play Order Programming

To program a play order select a track number from the numeric keys followed by the prog key until the desired selection is complete. During selection, the track number indicated in the player display will be followed by either P or — or no display. P indicates that the track is already selected, — indicates that the track can be selected. The prog key can also be used to delete tracks from a play order. To delete a track, press and hold the prog key until the prog indicator in the CD display illuminates then delete the track or tracks using the numeric keys followed each time by a further operation of the prog key. During deletion the track number indicated in the player display will be followed by either C or — or no display. C indicates that the track is already deleted, — indicates that the track can be deleted while no display indicates that this is the only track remaining and therefore cannot be deleted.The CD player can be programmed with a random play order (from stop with no play order already in place) by pressing prog followed by 1. Similarly, to program a reverse play order, press prog followed by 2.
Play orders can be reviewed by pressing prog while the player is either stopped or playing. The player display will then scroll through the selected tracks. The prog indicator on the player display will illuminate when a play order has been programmed. To clear the program memory press and hold the stop key.
