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.
