2.4.2 Audio Signal Outputs
NaimUniti provides audio signal outputs for a variety of
applications. Connections to the outputs are made via the
socket types listed in the following table:
Output
Type
Preamp out
Analogue stereo 4-pin DIN
Sub out 1
Analogue mono
Sub out 2
Analogue mono
Line out
Analogue stereo
Note:
The preamp output is intended for connection to an
upgrade or second power amplifier. The output is taken
after the NaimUniti volume control so a power amplifier
connected to it will respond to NaimUniti volume control
changes. The output always reflects the selected input
signal.
Note:
The two subwoofer outputs are mono and unfiltered.
They are taken after the NaimUniti volume control so
subwoofers connected to them will respond to NaimUniti
volume control changes. The outputs always reflect the
selected input signal and can be switched on or off in the
Speakers setup menu.
Note:
The stereo line output is intended to be connected
to a recording device. It is taken before the NaimUniti
volume control so does not reflect volume control
changes. The output always reflects the selected input
signal.
2. 5 S p eaker Out pu t s
A set of stereo speaker connection sockets is provided on
the NaimUniti rear panel. Custom Naim Audio loudspeaker
connectors are supplied to make the connection and in
order to comply with current European safety regulations
these should always be used. Naim Audio speaker cable
will provide the best results, however, a range of speaker
cable types may be used without risk of damage to the
amplifier. Contact your local Naim retailer for further
advice. Use equal lengths of speaker cable for each
channel.
Ensure when connecting speakers that they are "in
phase". That is, the positive and negative connection
orientation at both the speaker and amplifier ends of the
cable is the same for both channels.
2. 6 H ea dp hon e O u tp u t
NaimUniti is fitted on its front panel with a 3.5mm stereo
headphone socket. Insertion of a headphone plug will
mute the speaker outputs.
Note: NaimUniti controls and stores volume settings
separately for headphones and speakers.

2.9.1 Wired Network Connection
NaimUniti is fitted on its rear panel with a
switch offering two positions:
Chassis
the
position unless NaimUniti is connected in a hi-fi
system incorporating another earthed source component,
or mains "hum" is audible through the loudspeakers.
Contact your retailer, distributor or Naim for advice if
necessary.
Note:
"Connected" in the context above means an
analogue audio signal cable that includes an earth
connection.
Note:
All Naim CD players are earthed so the Signal
Ground switch should be set to floating if one is connected
in the system.
No damage will be done if the wrong Signal Ground
position is chosen however the system sound quality may
be compromised.
The NaimUniti negative analogue input and output
connections for each channel are common. The mains
earth (ground) should always be connected regardless of
what other equipment is used. The mains earth primarily
grounds the case and the electrostatic screen within the
transformer, and is only connected to the signal negative if
the
Signal Ground
switch is set to Chassis. In order to avoid
hum loops, the signal negative of the whole system should
be connected to the mains earth in one place only.
An iPod can be connected to the rear-mounted interface
socket using the Naim n-Link cable (available separately).
In addition to audio signals the NaimUniti iPod socket
carries iPod control signals as well as providing power to
charge the iPod battery.
NaimUniti is fitted on its rear panel with a standard RJ45
ethernet socket. This socket enables NaimUniti to join home
networks via a network router to access internet radio
data streams or to play audio files stored on appropriately
configured UPnP™ servers.
Ethernet-over-mains hardware may be used and provides
a simple and convenient method of wired home network
connection. However, depending on mains wiring factors
specific to each home environment, the presence of
network data on the mains supply may compromise
overall system sound quality. If any sound quality
compromise is found to be unacceptable, dedicated
network cabling should be installed or wireless networking
should be employed.
