Nait Xs - NAIM SUPERNAIT 3 Reference Manual

8. NAIT XS 3

The NAIT XS 3 is a very high performance stereo integrated amplifier that combines a
preamplifier providing five line-level analogue inputs and one moving magnet phono input with
a power amplifier rated at 70 Watts per channel. The NAIT XS 3 can be controlled by either
its remote handset or by a front panel mounted volume knob and mute and input selection
buttons. The NAIT XS 3 remote handset is described in Section 15 of this manual. A front panel
6.3mm jack socket enables the use of headphones with the NAIT XS 3.
A variety of power supply upgrade, alternative preamplifier and alternative or additional power
amplifier options are possible for the NAIT XS 3. A diagram illustrating one option is shown in
Section 10. If no power supply or alternative amplifier options are to be employed, the NAIT XS
3 preamp/power amp link plug, supplied in the accessory pack, must be fitted to the rear panel
"preamp out" and "power amp in" sockets. The link plug is shown fitted in Diagram 9.2.
Your NAIT XS 3 should be installed on a dedicated equipment stand intended for the purpose.
Do not stand it directly on top of another item of equipment. Care should be taken to ensure
that it is level. The amplifier should be installed in its final location before connecting cables or
switching on. Ensure that the volume is turned down before switching on.
8.1 Mains Power Connection
Connect the NAIT XS 3 to a mains power socket using either
the mains cable supplied or a Naim Power-Line.
8.2 Signal Inputs
The NAIT XS 3 front panel input buttons select the source input
signal to be routed to the integral power amplifier and the
loudspeakers or headphones. The six buttons are labelled cd,
tuner, stream, av, phono and aux 2.
The cd, tuner, stream and av input buttons correspond to
parallel DIN and RCA phono input sockets on the rear panel.
The phono input button corresponds to a pair of rca phono
sockets compatible with moving magnet (mm) cartridges.
The turntable earth lead should be connected to the ground
terminal when this input is being used.
Note: The stream and av sockets carry both inputs and
outputs. See Section 8.4 for more information.
The aux 2 input button corresponds to a DIN input socket
on the rear panel. The aux 2 DIN socket also carries a power
supply output intended to power a Naim StageLine or
SuperLine phono preamplifier.
Note: For optimum sound quality DIN sockets should
always be used in preference to RCA phono sockets.
Note: Where an input has DIN and phono socket options
only one should be connected at any one time.
Always use high quality interconnect cables to connect
sources to inputs. The Naim Hi-Line will produce the best
results.
8.3 Speaker Outputs
A set of stereo speaker connection sockets is provided on
the rear panel. Custom Naim loudspeaker connectors are
supplied to make the connection and in order to comply
with current European safety regulations these should
always be used. Naim speaker cable will provide the best
results, however, a wide range of speaker cable types can
be used without risk of damage to the amplifier.
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.
8.4 av and stream Outputs
The NAIT XS 3 av and stream inputs have associated
outputs that enable the selected input signal to be routed
externally; to an audio recording component for example.
Note: The av and stream outputs remain active while
their corresponding inputs are selected. Take care that
a feedback loop is not inadvertently created by the
simultaneous selection of input and output.
8.5 Headphone Output
The NAIT XS 3 headphone output is able to drive the
majority of headphone types. The 6.3mm (1/4") jack socket,
rather than the smaller 3.5mm jack socket, provides more
reliable connection and potentially higher sound quality.
Most high-quality headphones are supplied with an adaptor
that enables use with either 3.5mm or 6.3mm jack sockets.
Inserting a headphone plug will mute the NAIT XS 3 speaker
outputs. Removing the headphone plug will restore the
outputs.

Note: The NAIT XS 3
incorporates an AV Bypass
switch on its rear panel.
The switch should only be
set to "On" if the amplifier
is to be used in conjunction
with an AV processor in a
home theatre system. In
all other installations the
AV Bypass switch should
be set to "Off". Speaker
and amplifier damage
may occur if a signal is
inadvertently connected
to the NAIT XS 3 av input
while the AV Bypass switch
is "On".
