Powering Up/Down - NAIM 200 Serie Bedienungsanleitung

4.2 Input Connection Details
The NAP 250 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 flexible placement of the NAP 250.
Ground
Positive/
Hot
Negative/
Cold
Adapter cables are available to allow you to connect the NAP 250 to
preamplifiers 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 250 comes with custom Naim Audio loudspeaker connectors – these
provide the best, impedance-matched electrical connection, and ensure your
amplifier complies with current safety regulations.
Ensure when connecting speakers that they are 'in phase' – meaning
the amplifier's positive loudspeaker output is connected to the positive
loudspeaker input – and that the left and right outputs go to the correct
speaker.
4.4 System Automation
When using the NAP 250 with a compatible preamplifier – such as the NSC222
– you can synchronise power on/off and logo brightness across your system
by connecting the two with the supplied Optical System Automation Cable.
Simply plug the cable from the 'Remote Out' terminal of the preamplifier to
the 'Remote In' terminal on the NAP 250. It is possible to link further power
amplifiers using the 'Remote Out' terminal of the NAP 250.
If you require a longer distance between your preamplifier and the NAP
250 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 offers the best
performance.

4.5 Powering Up/Down

Once all your input and output connections are made, connect the supplied
mains lead to your NAP 250 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 250.
