5.3 Output connection details
The XLR sockets should be used for connection to a NAP 250 power amplifier. If the RCA
outputs are required (e.g. for a sub-woofer) they will need to be enabled from the
Naim App.
If an unbalanced power amplifier (e.g. an older Naim amplifier) is to be used with the NSC
222 the XLR sockets should be used with an appropriately wired cable.
5.4 Headphones
The headphone output has a separate volume setting. When headphones are inserted the
volume will be set to the level last used with headphones. When they are removed the
volume will be set back the level last used with speakers.
5.4 System automation
When using the NSC 222 with a compatible power amplifier – such as the NAP 250 – you
can synchronise power on/off and logo brightness across your system by connecting the
two products with the optical system automation cable supplied with the NAP 250.
Simply connect the cable from the ‘Remote Out’ terminal of the NSC 222 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 NSC 222 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.
5.5 Powering up/down
Once all your input and output connections are made, connect the supplied mains lead to
your NSC 222 and to mains power.
You can now power up the NSC 222 by pressing the standby button. If the NAP 250 is
connected via System Automation it will switch on in sequence.
It is the same procedure to switch off your NSC 222: turn off your NSC 222 preamplifier –
and NAP 250 connected via System Automation – by simply pressing the standby button
on the front panel, which will put the NSC 222 and the NAP 250 into standby. Avoid using
a mains outlet switch to turn your amplifier off.
5.6 Standby power settings
The NSC 222 has four power levels: standby, network standby, network standby with an
additional power requirement and powered for normal use.
“Standby” mode has an overall power consumption of less than 0.5W. The NSC 222 can be
woken up by pressing the standby button or from the remote control.
“Network standby” is <2W. The network needs to be connected (either wired or Wi-Fi) so
the NSC 222 can be woken up via the Naim App.
“Network standby with an additional power requirement”. The NSC 222 is fully powered
but with the display and logo turned off (it needs to be in this state to power a USB device
or act as a server).
“Powered for normal use” In normal use the NSC 222 uses about 25W.
By default, the NSC 222 is set to ‘auto standby’ - it automatically enters the appropriate
standby mode after a period not exceeding 20 minutes of inactivity. For the optimum
sound quality set the auto standby period to “Never” in the Naim App so the NSC 222 is
permanently powered up.
