4.2 Input Connection Details
The NAP350 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 NAP350.
Adapter cables are available to allow you to connect the NAP350 to preampliers with
RCA or DIN outputs.
4.3 Loudspeaker Cable and Connectors
For optimum performance, use Naim NACA5 or Super Lumina speaker cable, connected
in the correct direction (for example, NACA5 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 NAP350 comes with custom Naim Audio loudspeaker connectors – these provide the
best, impedance-matched electrical connection, and ensure your amplier complies with
current safety regulations.
Ensure when connecting speakers that they are ‘in phase’ – meaning the amplier’s
positive loudspeaker output is connected to the positive loudspeaker input – and that the
left and right ampliers go to the correct speaker.
4.4 System Automation
When using the NAP350 with a compatible preamplier – 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 preamplier to the ‘Remote In’ terminals on the NAP350
ampliers. It is possible to link further power ampliers using the ‘Remote Out’ terminals
of the NAP350.
If you require a longer distance between your preamplier and the NAP350 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 oers the best performance.
4.5 Powering Up/Down
Once all your input and output connections are made, connect the supplied mains leads to
your NAP350 ampliers 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 NAP350 ampliers.
You can now power up the NAP350 ampliers either by turning on your Naim preamplier
– connected via System Automation – or by simply pressing the power button on the front
panel of the power ampliers.
It is the same procedure to switch o your NAP350 ampliers: turn o your Naim
preamplier – connected via System Automation – or simply press the power button on
the front panel of the power ampliers, which will put them into standby. Avoid using a
mains outlet switch to turn your ampliers o.
