5.4 Powering Up/Down
Once all your input and output connections are made, connect the supplied mains lead to
your NAIT 50 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 NAIT 50.
You can now power up the NAIT 50 by simply pressing Standby button on the front panel
of the integrated amplifier.
5.5 Standby Power Settings
By default, the NAIT 50 is set to 'Auto Standby' - it automatically enters Standby mode
(where it consumes less than 0.5W of power) within 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.
6. Mains Power, Earthing and More
Use only the mains leads and plugs supplied with your NAIT 50, or the upgrade Naim
Power-Line mains cable.
Where fused plugs are used, 13 amp fuses should be fitted.
Do not wire voltage dependent resistors or noise suppressors into mains plugs; they
degrade the mains supply and the sound.
6.1 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.
6.2 Non-rewireable mains plugs
If a non-rewireable mains 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 electric shock hazard exists if the cut-off plug is inserted into a mains outlet.
6.3 Mains Circuits and Interference
A hi-fi 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 transformer in your NAIT 50.
Transformer hum is not transmitted through the speakers and has no effect 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 dedicated circuit will also generally
improve system performance. Only seek advice on the installation of a separate mains
circuit from a qualified electrician.
