NAIT XS 2
12 Amplifier Operation and Programmable Functions
The Nait XS 2 incorporates some programmable functions and operational nuances. These 
are described in the following paragraphs.
12.1 Automatic Input Switching
With
Automatic Input Switching
engaged the appropriate
source input will be selected as soon as any handset 
function for that (Naim) source component is operated. For 
example, if the tuner input is selected and the cd play key 
is pressed on the handset, the Nait XS 2 will automatically 
switch to the cd input. Automatic Input Switching can be 
programmed to operate on any combination of the 
cd
,
tuner
,
hdd
and
av
input buttons.
To enable Automatic Input Switching, first switch the Nait XS 
2 into program mode by pressing and holding the handset 
prog
key (with the handset in preamplifier mode). The front
panel
mute
button will illuminate if automatic switching is
already enabled. If it is not enabled it can be switched on 
by pressing the 
mute
button.
With automatic switching enabled, pressing the
mute
button again will reveal the inputs selected for auto 
switching by their indicators illuminating for a short time. 
Repeated operation of the 
mute
button will sequentially
select through each possible combination of
cd
,
tuner
,
hdd
and
av
inputs and auto switching disabled (all
indicators off). When the desired inputs selected for auto 
switching are indicated, stop pressing the button.
Automatic Input Switching only becomes operational 
on exit from program mode by pressing and holding the 
handset 
prog
key.
Note:
The Nait XS 2 will leave program mode automatically
if no control commands are received for five minutes.
Note:
In a few cases some further equipment configuration
may be required for auto switching to operate correctly. 
Please contact your retailer or local distributor for advice.
12.2 Handset Volume Control
The remote handset
volume
keys provide some alternative
control characteristics. A short press and release of a key 
will adjust by a preset “nudge”, while pressing and holding 
the key will result in three seconds of slow adjustment 
followed by continual fast adjustment.
Note:
The Nait XS 2 does not incorporate any facility for
channel balance adjustment.
12.3 Mute
Mute silences the outputs and can be selected or 
deselected by pressing the front panel 
mute
button or
remote handset
mute
key.
12.4 Display
The Nait XS 2 front panel button illumination can 
be switched off by pressing the remote handset (in 
preamplifier mode) 
disp
function. Any subsequent handset
or front panel operation will temporarily restore the display. 
A second operation of the 
disp
function will restore the
display.
12.5 Switch-on
After switch-on the Nait XS 2 will remain muted for 30 
seconds while control systems and circuits stabilise.
12.6 Remote Control
The Narcom 4 remote handset supplied with the 
Nait XS 2 duplicates all configuration and control functions. 
See Section 18 for more information.
12.7 Defaults
To restore all Nait XS 2 programmable settings to the 
factory defaults press and hold the remote handset 
disp
key while the unit is in program mode. The Nait XS 2 will exit 
from program mode following this operation.
12.8 Fault Conditions
The Nait XS 2 will indicate fault conditions by flashing front 
panel button buttons. The following table lists the fault 
indications.
