5.3 System automation
When using the NAC 332 with a compatible streamer and power amplifier – such as the
NSS 333 and NAP 350 – you can synchronise power on/off and logo brightness across your
system by connecting the NAC 332 with the optical system automation cables supplied
with the NAP 350.
The NSS 333 and NAC 332 use the Zigbee system to synchronise their functions. Press
any button (except standby) on the front panel of the NSS 333 and NAC 332 to pair them
together.
Use the 'Remote Out' terminals on the NAC 332 to link the 'Remote in' terminals on the
NAP 350. It is possible to link further power amplifiers using the 'Remote out' terminals of
the NAP 350.
If you require a longer distance between your NAC 332 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 offers the best performance.
5.4 Powering up/down
Once all your input and output connections are made, connect the supplied mains lead to
your NAC 332 and to mains power.
You can now power up the NAC 332 by pressing the standby button.
If the NSS 333, NAC 332 and a pair of NAP 350 units is connected via System Automation
they will switch on in sequence.
It is the same procedure to switch off your NAC 332: turn off your NSS 333, NAC 332 and
NAP 350 connected via System Automation, by simply pressing the standby button on the
front panel of the NSS 333 or NAC 332, which will put your complete system into standby.
Avoid using a mains outlet switch to turn your amplifiers off.
5.5 Standby power settings
The NAC 332 has three power levels: standby, standby with instant on and powered for
normal use.
'Standby' mode has an overall power consumption of less than 0.5W. The NAC 332 can be
woken up by pressing the standby button or from the remote control.
'Standby with instant on' leaves the NAC 332 fully powered, but with the logo turned off.
'Powered for normal use' In this mode the NAC 332 uses about 20W.
By default, the NAC 332 rear panel switch is set to 'auto standby' - it automatically enters
standby mode after a period not exceeding 20 minutes of inactivity. For the optimum
sound quality set the switch to the "instant on" position. This will keep the NAC 332
permanently powered up. With the switch in this position, if the standby button is pressed,
the NAC 332 will remain powered up, but the logo will turn off.
5.6 Naim logo brightness settings
You can choose the brightness level of the LED indicators and Naim logo on your NAC 332
using the brightness buttons on the rear panel and the remote control. If you are using
Naim NAC 332 and NAP 350 amplifiers connected via System Automation the brightness
of all logos will be synchronised.
