NaimUniti Integrated Amplifier
5 NaimUniti Integrated Amplifier
NaimUniti incorporates a high performance integrated preamplifier and power amplifier
based on established Naim design principles. The preamplifier is able to handle both
analogue and digital audio signals and, in addition to NaimUniti’s internal CD player,
multi-format radio and network interface it has inputs for five external analogue and five
external digital signals.
Using the NaimUniti amplifier is simply a matter of selecting the desired input and setting
the listening volume level.
5.1 Selecting Inputs
Inputscanbeselectedbypressingthefrontpanelinput
button,thehandsetup(5)anddown(6)keysoroneof
the handset input selection keys.
Note: The front panel input is automatically selected as
soon as a plug is inserted.
Pressing the front panel inputbuttonorhandsetup(5)
and down(6)keysscrollsthroughandselectstheinputsin
the following order:
CD, FM(radio),DAB(radio),iRadio, UPnP™(Network
UPnP™),iPod, USB, Front(frontpanelanalogue/digital),
Analogue 1, Analogue 2, Analogue 3, Phono(Analogue4),
Digital 1, Digital 2, Digital 3, Digital 4.
Note: These are the default input names. They may be
altered within the NaimUniti set up menus. See Section 4.3.
Inputs can also be disabled so that they are hidden from
selection.
Pressing one of the handset input selection keys either
directly selects a single input or scrolls through a group
ofinputs.Forexample,bydefault,pressingtheCD input
selection key selects the CD input, while pressing the radio
input selection key scrolls through a group comprising the
FM, DAB and iRadio inputs.
Note: The default input selection key assignments may be
altered within the NaimUniti set up menus. See Section
4.8.2.
Selecting an input will route that input’s audio signal to the
NaimUniti outputs.
NaimUniti will momentarily display input names as they are
selectedbeforedisplayinginputspecificinformation;CD
track or radio preset for example.
Ifaninputisnotoperational(forexample,noUSBmemory
stickisattached)whenselected,NaimUnitiwilldisplaya
descriptive alert message.
5.2 Volume Control
NaimUnitivolumecontrolisachievedbyusingeitherthe
front panel –vol and vol+buttonsorthehandsetvol–
and vol+ keys. The volume control affects the speaker,
headphone,subwooferandpreamplifieroutputs.
Note: In list or setup modes front panel volume control is
disabled. Volume can still be controlled using the handset
volume keys.
The mute function silences the NaimUniti speaker,
headphone,preamplifierandsubwooferoutputsandis
engagedordisengagedbypressingthefrontpanelmute

display volume icon flashing.
5.3 Amplifier Display
In normal operation the NaimUniti front panel display
primarily shows information relating to the selected input. It
will change temporarily to show amplifier adjustments such
as volume level and signal mute state as these are made.
5.4 Signal Outputs
In addition to its speaker outputs the NaimUniti integrated
amplifier provides a stereo line output, two mono unfiltered
subwooferoutputs,astereopreamplifieroutput,anda
headphone output.
ThelineoutputcanbeusedtoconnectNaimUnititoan
analogue recording device. The NaimUniti volume control
has no effect on the line output level.

5.5 Amplifier Fault Warnings
In the unlikely event that the NaimUniti power amplifier is
overloaded, exceeds its normal operating temperature or
malfunctions, its output will mute and the display will show
a warning message.
