3. NAP350 Set Up
Your pair of NAP350 ampliers needs to be connected to a preamplier (such as the
matching NAC 332), but before you do, please ensure all components are in their nal
positions and disconnected from mains power.
For optimum performance, use a dedicated hi- support – ideally Naim Fraim – with the
preamplier sited above the power amplier, as shown.
Ensure all equipment is o before connecting.

4
EN
Connect the supplied XLR cable from the balanced XLR outputs of your preamplier to the
balanced input of the NAP350. Repeat with your other NAP350 and ensure the cables
are channel-matched: the pre-amplier left output connected to the power amplier used
for the left speaker etc. More in section 4.2. Please ensure that the XLR plugs are inserted
correctly, which is achieve with the Naim logo on the plug facing upwards.
If you are using the NAP350 with matching Naim preamplier (see section 4.4), connect
the supplied system automation cable to the preamplier’s Remote Out terminal.
Connect the other end of the system automation cable to the Remote In terminal on each
NAP350.

Ensure the volume is turned down on the preamplier before switching on the NAP350
ampliers. If you are using the system automation connection to a Naim preamplier, the
power ampliers will switch on automatically when any of the standby buttons is pressed.
If you are using a dierent preamplier, press the Standby button on the front panel of
both NAP350 ampliers.
4. Tips on Installing and Using Your NAP350
We know you are eager to enjoy your new NAP350, but we promise it will sound even
better once you have followed these guidelines, all designed to help you experience your
power ampliers without compromise.
4.1 Unboxing and positioning
Your NAP 350 uses high-quality components, including a substantial power transformer
and durable aluminium casing. That means the NAP 350 weighs in at 16.5kg, so please
take care when lifting or moving it, and ensure the surface you plan to place it on is stable
and can support its weight.
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 NAP350 on a Fraim glass shelf on a suitable piece
of furniture, to provide solid but discreet support.
Your NAP350 features fan-assisted cooling, designed to activate when your amplier
runs at high volumes for a sustained time. Please ensure the heat outlet is not covered; we
would not recommend using the NAP350 in a closed, non-vented cabinet.
Never stack Naim products on top of each other, and if you are placing them side-by-
side, please leave some distance between the units. Equally, connected products should
not sit too far apart: the maximum separation distance is that allowed 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.

EN
4.2 Input Connection Details
The NAP350 features industry standard XLR balanced inputs for audio. Balanced
connections are a low-noise solution and are able to run over long distances – enabling
more exible placement of the NAP350.
Adapter cables are available to allow you to connect the NAP350 to preampliers with
RCA or DIN outputs.
4.3 Loudspeaker Cable and Connectors
For optimum performance, use Naim NACA5 or Super Lumina speaker cable, connected
in the correct direction (for example, NACA5 printed arrows pointing toward the
loudspeaker).
It is important your pair of speaker cables are both the same length, up to a recommended
maximum of 20m. Unlike some earlier Naim designs, we do not mandate a minimum
speaker cable length, but would still suggest you avoid sub-2m lengths.
Your NAP350 comes with custom Naim Audio loudspeaker connectors – these provide the
best, impedance-matched electrical connection, and ensure your amplier complies with
current safety regulations.
Ensure when connecting speakers that they are ‘in phase’ – meaning the amplier’s
positive loudspeaker output is connected to the positive loudspeaker input – and that the
left and right ampliers go to the correct speaker.
4.4 System Automation
When using the NAP350 with a compatible preamplier – such as the NAC 332 – you can
synchronise power on/o and logo brightness across your system by connecting them
with the supplied Optical System Automation Cables. Simply plug the cables from the
‘Remote Out’ terminals of the preamplier to the ‘Remote In’ terminals on the NAP350
ampliers. It is possible to link further power ampliers using the ‘Remote Out’ terminals
of the NAP350.
If you require a longer distance between your preamplier and the NAP350 than the
supplied cable allows for, you can use a replacement 3.5mm to 3.5mm optical cable
to the required length. It is also possible to use standard analogue cables with 3.5mm
connectors, but an optical cable oers the best performance.
4.5 Powering Up/Down
Once all your input and output connections are made, connect the supplied mains leads to
your NAP350 ampliers and to mains power. Please note: your source - such as a streamer
or CD player – and any associated external power supplies should be switched on before
you switch on your NAP350 ampliers.
You can now power up the NAP350 ampliers either by turning on your Naim preamplier
– connected via System Automation – or by simply pressing the power button on the front
panel of the power ampliers.
It is the same procedure to switch o your NAP350 ampliers: turn o your Naim
preamplier – connected via System Automation – or simply press the power button on
the front panel of the power ampliers, which will put them into standby. Avoid using a
mains outlet switch to turn your ampliers o.

EN
4.6 Standby Power Settings
By default, the NAP350 is set to ‘Auto Standby’ - it automatically enters Standby mode
(where it consumes less than 0.5W of power) after 19 minutes of inactivity. Music Sensing
will wake the amp from Standby when it detects an input signal.
For the optimum sound quality, switch the Standby setting on the rear panel to ‘Instant on’,
which keeps all sensitive audio circuits permanently powered up.
Please note Music Sensing is disabled when it receives a system automation command; if
the NAP350 is manually put into Standby via the Standby button, or when ‘Instant On’ is
enabled.
4.7 Naim Logo Brightness Settings
You can choose the brightness level of the Naim logo on your NAP350. If you are using a
Naim preamplier connected via System Automation, you can synchronise the brightness
of all the logos from the preamp. Alternatively, you can set the NAP350 via the brightness
toggle switch on the rear panel.
PLEASE NOTE: the brightness button also functions as a full NAP350 reset button when
it is pressed for 3 seconds, so it is best to make your logo brightness choices quick and
decisive!
4.8 USB Update
Your NAP350 has a micro USB terminal, but this is for service use only.
5. Mains power, Earthing and More
Use only the main leads and plugs supplied with your NAP350, or the upgrade Naim
Power-Line mains cable. Where fused plugs are used, 13 amp fuses should be tted. Do
not wire voltage dependent resistors or noise suppressors into mains plugs; they degrade
the mains supply and the sound.
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, a Naim
streamer has a ground lift switch. Set this to “default” if no other source connects mains
earth to signal ground. This setting will give best sound quality.
5.2 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.
5.3 Mains Circuits and Interference
A hi- system usually shares a mains power circuit with other household equipment,
some of which can cause distortion that may manifest as mechanical hum from mains
transformers, including the large transformer in your NAP350.
Transformer hum is not transmitted through the speakers and has no eect on the
performance of the system; however, 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) will also generally improve system performance. Only seek advice on the
installation of a separate mains circuit from a qualied electrician.
5.4 Lightning Precautions
Your Naim system should be turned o and fully disconnected from mains power when
there is a risk of a lightning strike, to protect from potential damage.

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 NAP350.
6.1 Running In
Naim products are handcrafted from a carefully selected range of high- quality
components. Your NAP350 will sound superb out of the box, but its performance may
improve further still as all these various components power up and interact in their rst
few weeks of use. Keeping your system powered up will assist this process.
6.2 Cleaning Your Product and Connections
Naim recommends using only the supplied cleaning cloth to lightly dust any product
surfaces. Cleaning products may contain ingredients that can adversely aect cosmetic
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 product (and any connected equipment),
unplug all connections from their sockets and rmly push them in again. Contact cleaners
and so-called ‘enhancers’ should not be used, as they can leave deposits that can degrade
the sound of your system.
6.3 Resetting your NAP350
To reset your NAP350 to default settings, press the ‘Brightness’ button on the rear panel
for 3 seconds.
7. Support
Consumer protection varies from country to country. In most territories, the retailer you
bought your Naim product from should be your primary contact if you are experiencing
problems with your unit. 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.
You can nd a range of support articles for each Naim product online at Naimaudio.com
If you are still experiencing an issue with your Naim product, contact us directly for help
and advice, at [e-mail]

10
EN
10. Product Recycling
Products that display the crossed-out wheeled bin logo cannot be disposed of
as domestic waste. These products must be disposed of at facilities capable of
recycling them and appropriately handling any waste by-products.
Contact your local authority for details of the nearest such facility.
Appropriate recycling and waste disposal helps conserve resources and protects the
environment from contamination.
8. Service and Updates
Any repairs or hardware updates should only be made by an authorised Naim service
centre or at the Naim HQ itself. Many components are custom made, tested or matched
and appropriate replacements are often unobtainable from other sources. Please contact
your local Naim retailer with any service or repair queries.

3. Mise en place du NAP350
Votre paire d’amplicateurs NAP350 doit être raccordé à un préamplicateur (tel que
le NAC332 correspondant) mais, avant de le faire, vous devez vous assurer que tous les
composants se trouvent à leur emplacement dénitif et sont débranchés du secteur.
Pour des performances optimales, utilisez un support hi- dédié (idéalement NaimFraim)
et placez le préamplicateur au-dessus de l’amplicateur de puissance, comme illustré.
Avant de procéder au raccordement, vériez que tous les équipements sont éteints.

4
FR
Branchez le câble XLR fourni entre les sorties XLR symétriques de votre préamplicateur
et l’entrée symétrique du NAP350. Faites de même avec l'autre NAP350 et vériez que
les câbles sont bien appariés: la sortie gauche du préamplicateur avec l’amplicateur de
puissance utilisé pour l’enceinte de gauche, etc. Pour plus d’informations, se reporter à la
section4.2. Veillez à ce que les ches XLR soient insérées correctement, ce qui est le cas
quand le logo Naim de la che est vers le haut.
Si vous utilisez le NAP350 avec un préamplicateur Naim correspondant (voir section4.4),
raccordez le câble d’automatisation système fourni avec le port de sortie à distance du
préamplicateur.
Branchez l’autre extrémité du câble d’automatisation système au port d’entrée à distance
de chaque NAP350.
