identify the type of plug inserted and handle the signal
appropriately.
Alwaysusehighqualityinterconnectcablestoconnect
sources to NaimUniti inputs.
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.
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.

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 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 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 iPod Interface
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.
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
networkcablingshouldbeinstalledorwirelessnetworking
shouldbeemployed.

NaimUniti Installation and Connection
2.9.2 Wireless Network Connection
If NaimUniti is to connect wirelessly to the home network
thesuppliedWiFi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: 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.
2.10 Control Sockets
NaimUniti is fitted on its rear panel with a standard
RS232 interface socket and a Remote in socket. These
socketsenableNaimUnititobeintegratedwithinhome
automation systems. Contactyourretailer,distributoror
Naimformoreinformationifrequired.
