NaimUniti Introduction
1 NaimUniti Introduction
NaimUniti is a highly capable product that will repay time and effort spent on installation
and setup. We strongly recommend that you read this manual. NaimUniti effectively
incorporates five separate elements. Each of these is introduced in the following
paragraphs and subsequently described in full detail in Sections 5 to 9. The NaimUniti
elements are:
An Integrated Stereo Amplifier Introduced below and fully described in Section 5
A CD Player Introduced below and fully described in Section 6
A Multi-mode Radio Introduced below and fully described in Section 7
A UPnP™ Audio Interface Introduced below and fully described in Section 8
A USB/iPod Audio Interface Introduced below and fully described in Section 9
Prior to the sections describing NaimUniti’s elements, Section 2 covers its installation,
Section 3 describes its operation and Section 4 describes its setup.
1.1 The Integrated Amplifier
1.1.1 Inputs
NaimUniti incorporates an audio preamplifier that provides
five analogue and five S/PDIF digital audio external
inputs. The preamplifier also accepts internal inputs from
NaimUniti’s integrated CD player and FM/DAB tuner.
In addition to conventional analogue and digital input
signals, the NaimUniti preamplifier can accommodate the
following external peripheral inputs:
• iPodmodelsandUSBmemoryviaaUSBinterface.
• Internetradioanduniversalplugandplay(UPnP™)
servers via an ethernet network socket or wireless
network connection.
1.1.2 Signal Outputs
The NaimUniti preamplifier provides the following analogue
signal outputs:
• Alineoutput(prevolumeandbalancecontrols).
• Twomonounfilteredsubwooferoutputs
(post volume and balance controls).
• Apreamplifieroutput
(post volume and balance controls).
• Aheadphoneoutput
(post volume and balance controls).
1.1.3 Controls
The NaimUniti preamplifier provides volume, balance, input
selection and mute control from either the front panel or
the supplied remote handset.
1.1.4 Speaker Outputs
NaimUniti incorporates a stereo power amplifier rated at
50 Watts per channel into 8 Ohms. The power amplifier is
designed to drive one pair of speakers via the sockets on
the NaimUniti rear panel.
1.2 The CD Player
NaimUniti incorporates a CD player based on the same
swing-out CD drawer and transport used in other Naim CD
players. The transport is able to play standard “Red Book”
CDs and CDR discs. CD track order can be programmed
or tracks can be shuffled (played randomly).
1.3 The Multi-mode Radio
The NaimUniti multi-mode radio combines an FM/DAB
(Digital Audio Broadcasting) tuner and an internet radio
(iRadio) player. A total of 40 radio stations across all three
modes can be stored as presets. In FM and DAB mode
stations are tuned by NaimUniti scanning the respective
transmission bands. In iRadio mode NaimUniti receives
data streams and a list of available radio stations from
a dedicated internet server. iRadio requires broadband
internet access via a home network connection.
The NaimUniti DAB module incorporates full broadcast
and station display capabilities. The FM module is fully RDS
(Radio Data System) capable.
Note: DAB and RDS broadcasts are not available in all
territories.
1.4 The UPnP™ Audio Interface
NaimUniti can connect to a home network and play audio
files stored on UPnP™ drives.
1.5 The USB/iPod Interface
NaimUniti incorporates a front panel USB interface socket
that enables audio files stored on USB memory sticks and
Apple iPod models to be selected and played.
Note: 5th generation and later, and all iPod touch models,
are compatible with the NaimUniti USB interface.
Note: Earlier iPod and other portable music players may be
connected from their headphone sockets to NaimUniti’s
front panel analogue input using a 3.5mm stereo jack
cable. Player control via NaimUniti’s user interface will not
however be possible.

NaimUniti Installation and Connection
2 NaimUniti Installation and Connection
NaimUniti should be installed on an equipment stand intended for the purpose. Do not
stand it directly on top of another item of equipment and ensure it is well ventilated. Care
should be taken to ensure that it is level. It should be installed in its final location before
connecting cables or switching on. NaimUniti has no standby mode and is intended to be
left switched on.
A transit screw on the underside of the NaimUniti case should be removed before use and
replaced if the unit is to be moved. This transit screw must not be used in any other Naim
product. Handle NaimUniti with extra care once the transit screw is removed.
Connecting NaimUniti to mains power and to a variety of audio peripherals and sources
is described in the following paragraphs. Diagram 2.1 illustrates the NaimUniti rear panel
connection sockets.

2.2 Mains Power Connection
Connect NaimUniti to a mains power socket using either
the mains cable supplied or a Naim Power-Line.
2.3 FM/DAB Aerial Connection
In order to enable high quality FM and DAB radio,
NaimUniti requires a strong, interference-free radio signal.
Its rear panel FM/DAB Aerial socket must be connected,
via 75 Ohm low-loss coaxial cable, to a suitable aerial. The
aerial should be mounted clear of large obstructions and
as high as possible; ideally on a roof.
Note: Your local retailer should be able to offer advice on
a suitable aerial and aerial installer.
2.4 Audio Signal Connections
2.4.1 Audio Signal Inputs
NaimUniti provides five stereo analogue inputs and five
S/PDIF digital inputs including one combined analogue/
digital input socket. Connection to the inputs is made via
a variety of socket types. The following table lists the inputs
and their socket types:
signal ground switch
preamp output
subwoofer outputs
Input Type Socket
an. 1 Analogue RCA phonos
an. 2 Analogue RCA phonos
an. 3 Analogue RCA phonos
phono Analogue 240° 5 pin DIN
front panel Analogue 3.5mm jack
Digital 3.5mm mini-TosLink jack
dig. 1 Digital Coaxial (RCA phono)
dig. 2 Digital Optical (TosLink)
dig. 3 Digital Coaxial (RCA phono)
dig. 4 Digital Optical (TosLink)
Note: The Phono DIN socket carries a power supply output
intended to power a Naim phono preamplifier. A turntable
cannot be used with NaimUniti without an external phono
preamplifier.
Note: The front panel analogue/digital jack socket can
accept both conventional analogue 3.5mm plugs and
mini-TosLink optical digital plugs. It will automatically
identify the type of plug inserted and handle the signal
appropriately.
Always use high quality interconnect cables to connect
sources to NaimUniti inputs.

NaimUniti Installation and Connection
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 Socket
Preamp out Analogue stereo 4-pin DIN
Sub out 1 Analogue mono RCA phono
Sub out 2 Analogue mono RCA phono
Line out Analogue stereo RCA phonos
Note: The preamp output is intended for connection to an
upgrade or second power amplifier. The output is taken
after the NaimUniti volume and balance controls so a
power amplifier connected to it will respond to NaimUniti
volume and balance 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 and balance controls so does not reflect volume
or balance control changes. The output always reflects the
selected input signal.
2.5 Speaker Outputs
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 Headphone Output
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.
2.7 Signal Ground Switch
NaimUniti is fitted on its rear panel with a Signal Ground
switch offering two positions: Chassis or Floating. Select
the Chassis 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.
2.7.1 General Audio Connection Notes
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.
2.8 USB/iPod Interface
NaimUniti is fitted with a front panel USB interface intended
for the connection of Apple iPod models and USB memory
sticks carrying audio files. The USB interface should not be
used for any other purpose.
Depending on the setup options chosen (see Section
4.3.5), iPod batteries will be charged when connected to
the USB interface.
2.9 Network Connections
2.9.1 Wired Network Connection
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
3
NaimUniti Installation and Connection
network cabling should be installed or wireless networking
should be employed.
2.9.2 Wireless Network Connection
If NaimUniti is to connect wirelessly to the home network
the supplied Wi-Fi antenna must be fitted to the rear panel
wireless antenna socket. Wireless configuration will also
be necessary before NaimUniti is able to connect to the
network. See Section 4.6.1 of this manual.
2.9.3 Network Settings
NaimUniti is set up when originally shipped not to require
any on-site network configuration but to connect to a
network automatically (it uses DHCP by default). However,
if your NaimUniti has been previously used, its network
configuration may have been altered leaving it unable
to connect automatically. If this appears to be the case
ensure that DHCP is selected in the Network Settings menu
and re-start NaimUniti. If problems still persist contact your
retailer, installer or Naim Audio directly. See Section 4.6.
Note: Before reporting network connection problems carry
out a Factory Resest operation and try again. Select Reset
All Settings from the Factory Settings setup menu. See
Section 4.9.
Note: A NaimUniti switched on without a working wired
network connection will only be able to connect to
a home network wirelessly. To use an ethernet (wired)
connection, switch NaimUniti off, connect the network and
switch it on again.
Note: For internet radio to operate NaimUniti requires
connection to a broadband internet service via a router/
modem with a built-in firewall.
2.9 Control Sockets
NaimUniti is fitted on its rear panel with a standard RS232
interface socket and a Remote in socket. This socket is
intended to enable firmware upgrades and diagnostic
tests to be carried out. Contact your retailer, distributor or
Naim for more information if required.
