2. Features and Connections
Getting to know your product
Both NVC TT and NPX TT provide the foundations of a complete vinyl replay system. The
simple addition of a turntable is needed for before connection to an amplier. Diagrams
illustrating the connection are shown in Section 3.
The NVC TT has been designed for best performance when connected via DIN to Naim
amplication, but can be used with any amplier with a standard RCA line level input.
Your devices should be installed on a dedicated equipment. Do not stand them directly on
top of another item of equipment. Care should be taken to ensure that all elements are level.
Before switching them on and connecting the cables, the turntable, phono stage and power
supply should be installed in their nal location. Ensure that the volume on the connected
amplier is turned down before switching it on.

4. Tips on Installing and Using your Device
We know you are eager to enjoy your new Phono Stage and / or Power Supply, but it will
sound even better once these guidelines have been followed. They are designed to help you
experience your power amplier without compromise.
4.1 Unboxing and Positioning
Some Naim equipment is extremely heavy. Check the weight of the equipment prior to
lifting and if necessary, get some help to carry it safely. Ensure that your equipment rack or
table can easily support the weight and is stable.
For optimum performance, use your Naim products on a dedicated hi- equipment rack
ideally the Naim Fraim or Fraim Lite – to minimise vibrations that can aect sound. No
room for a rack? Consider placing your product on a Fraim glass shelf on a suitable piece
of furniture, to provide solid but discreet support.
Never stack Naim products on top of each other. If they are placed side-by-side, leave
some space between the units. Equally, connected products should not be too far apart:
the maximum distance is given by the supplied interconnect lead.
To reduce the risk of audible hum from the loudspeakers do not place power supplies or
power ampliers close to source components.

4.3 Connectors
For both safe use and performance reasons, do not modify the standard cables supplied.
4.3.1 Interconnect Cables
Naim interconnect cables that share the same connector on each end are marked with a
band to establish correct orientation. The band denotes the end that connects to the signal
source. Naim Super Lumina interconnect cable will provide the best results.
4.3.2 Signal Outputs
The NVC TT Phono Stage features audio outputs on 5 pin DIN and RCA outputs, and an 8
pin DIN power supply input (NSC 222, NAC 332 or NPX TT), making it easy to connect to a
variety of Naim and other manufacturers’ equipment. Always use high quality interconnect
cables to connect the phono stage to the amplier inputs.
4.3.3 Mains Connection
Connect the NPX TT Power Supply to a mains power socket using either the mains lead
supplied or a Naim Power-Line.
4.4 Powering Up/Down
Once all your input and output connections are made, connect the supplied mains lead to
your NPX TT and then to a mains power source.
Ensure your sources - your turntable, for example - and any associated external power
supplies are switched on before you switch on your NPX TT.
Always use the power switch on the product rather than a mains outlet switch for both
powering and on and o.
A “thump” may be heard from the loudspeakers as power ampliers 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 o.
4.5 Standby Power Settings
The NVC TT Phono Stage powers down into a sleep mode after 20 minutes as its default.
In this sleep mode (‘Auto Standby’) the system consumes less than 0.5W of power. The
‘Instant On’ feature sets your system to a mode that leaves the sensitive audio circuitry
permanently powered for the best sound quality.
The standby power setting on the NVC TT phono stage is only applicable when it is
powered by the NPX TT power supply. The standby power setting on the NVC TT phono
stage depends on the power supply used. It needs to be powered by a pre-amplier which
can control the standby settings.
4.6 Cartridge Selection
The NVC TT Phono Stage features adjustable settings to enable the best performance of
a connected cartridge. It is possible to adjust both gain, capacitive and resistive load for
Moving Coil (MC) cartridges. The adjustment switches do not apply for Moving Magnet
(MM) cartridges as they typically have a much higher output.
The NVC TT is preset to MC mode with cartridge loading values of 100ohms and 1000pF
and the high gain setting. The gain and loading can be adjusted using the rear panel
switches to match your cartridge choice. Check with the cartridge manufacturer for the
recommended values. They can be adjusted for personal preference.
10
For example:
· Adding more capacitance may reduce any perceived system forwardness.
· Making the resistance lower can help counteract any perceived excessive liveliness
· Switching between high and low gain may help match input levels across a system.
If you use a moving magnet cartridge, set the mode to MM. When using the NVC TT in
MM mode set the MC gain to high and the loading values to 1k and 100pF.
4.7 Naim Logo Brightness Settings
The brightness of the product logos can be set using the rear panel switch on the NVC TT
or the rear panel push button on the NPX TT.
4.8 USB Update
The NPX TT has a micro-USB socket on its rear panel for service use only.
5. Mains Power, Earthing and More
Only use the mains lead and plugs supplied with your Naim products, or the upgrade Naim
Power-Line mains lead.
5.1 Earthing
In order to avoid hum loops, the signal ground of the whole system should be connected to
the mains earth in one place. Typically, this is at the primary source.
For example, if your turntable has a mains earth and you have a Naim streamer in the
system, its ground lift switch should be set to "Floating”. This is the best setting for sound
quality.
5.2 Equipment Fuses
Mains powered Naim Audio equipment is tted with a mains fuse on the rear panel
adjacent to the mains input socket. If necessary; replace it only with the spare fuse
supplied or with an identical fuse. Repeated failure of the fuse indicates a fault that should
be investigated by your retailer or Naim itself.
Where fused plugs are used, 13 amp fuses should be tted. 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.
5.3 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-o plug is inserted into a mains outlet.
5.4 Mains Circuits and Cables/Interference
A hi- system usually shares a mains power circuit with other household equipment, some
of which can cause distortion that may manifest mechanical hum from mains transformers,
including the transformer in your NPX TT.
Transformer hum is not transmitted through the speakers and has no eect on the
performance of the system; however, a careful positioning of your Naim system may
reduce it, as may a separate, dedicated mains circuit. Such a circuit (ideally with a 30 or
45 Amp rating) generally also improves system performance. Only seek advice on the
installation of a separate mains circuit from a qualied electrician.
5.5 Radio Interference
In some circumstances, depending on where you live and the earthing arrangements of
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 location of the equipment may be critical.
11
Susceptibility to radio frequency interference is related to the wide internal bandwidth
necessary for high sound quality.
Contact your dealer or the factory for advice on dealing with radio frequency interference.
5.6 Lightning Precautions
To protect it from potential damage, your Naim system should be turned o and fully
disconnected from mains power when there is a risk of a lightning strike.
6. Further Tips and Advice
Now you have all the essentials sorted, let us move onto a few more things that you can do
to optimise the performance of your new devices.
6.1 Running In
Naim products are hand-crafted from a carefully selected range of high-quality
components. Your products will sound superb out of the box, but their performance can
improve further still as all these various components power up and interact in their rst
few weeks of use. Keeping your system powered up before using it will assist this process.
6.2 Cleaning your Product and Connections
We recommend using only the supplied cleaning cloth to lightly dust any surfaces of
the product. Cleaning products may contain ingredients that can likely degrade surface
treatments and coatings.
Keep interconnect plugs and sockets clean and free from corrosion. The easiest way to
achieve this is to fully power o your Naim products (and any connected equipment),
unplug all connections from their sockets and rmly push them in again. Do not use
contact cleaners and so-called ‘enhancers, as they can leave deposits that can degrade the
sound of your system.
6.3 Resetting your Device
The NPX TT can be reset to factory settings by pressing the "Brightness/Reset" button for
more than 3 seconds.
7. Support
The consumers’ legal guarantee of conformity varies depending on the country. In most
countries, the dealer where you purchased your Naim product is your main interlocutor
in the event of a defect. If the equipment is non-compliant, it must be sent to the dealer,
in its original packaging, who will analyse it and determine where the breakdown comes
from. If the equipment is under warranty and conditions are met, the equipment will be
repaired or replaced according to the conditions applicable to the legal warranty on the
date of purchase of the device. Otherwise, a repair estimate will be submitted. The legal
guarantee does not cover damage from a misuse or a wrong connection (burnt mobile
coils for instance). France excluded, Naim equipment is covered by a warranty whose
conditions are locally set or carried out by the ocial Naim dealer of each country, in
compliance with the laws of the concerned territory. In France, every Naim equipment is
covered by a two-year legal guarantee from the date of purchase.
A defect can be caused by a failure of the system or by the installation, contact your
dealer. You can nd a range of support articles for each Naim product online
at www.naimaudio.com
If you are still experiencing an issue with your Naim product, contact us directly for help
and advice, at support@naimaudio.com
8. Service and Updates
Any repairs or hardware updates must be carried out by a professional. We recommend
you to contact an authorised Naim service centre as many components are custom made,
tested or paired. Please contact your local Naim retailer for any service or repair queries.

2. Caractéristiques et ports de connexion
Faites connaissance avec votre produit
NVC TT et NPX TT sont les bases d’un système complet de diusion sur vinyle. Le simple
ajout d’un tourne-disque est nécessaire avant d'eectuer la connexion à un amplicateur. Les
schémas illustrant le branchement gurent à la section3.
NVC TT a été conçu pour fournir les meilleures performances lorsqu’il est connecté via un
DIN à un amplicateur Naim, mais il peut être utilisé avec n’importe quel amplicateur doté
d’une entrée ligne RCA standard.
Vos appareils doivent être installés sur un support d’équipement dédié. Ne les posez pas
directement au-dessus d’un autre appareil. Veillez à ce tous les éléments soient bien de
niveau.
Avant leur mise en marche et la connexion des câbles, le tourne-disque, l’étage phono et
l’alimentation doivent être installés à leur emplacement dénitif. Assurez-vous que le volume
de l’amplicateur connecté est baissé avant de l’allumer.
