NAIT 5si
Automatic Input Switching only becomes operational on exit
from program mode by pressing and holding the handset
prog key.
Note: The NAIT 5si 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.
14.2 AV Bypass
The NAIT 5si can be integrated within a multi-channel home
theatre system, driving the front left and right channel
speakers, by engaging its AV Bypass mode. AV Bypass mode
enables a home theatre processor to take over volume control
of signals connected to the NAIT 5si av input.
To select AV Bypass, first switch the NAIT 5si into program
mode by pressing and holding the handset prog key (with
the handset in preamplifier mode). The front panel av button
will illuminate if AV Bypass is selected. If it is not enabled it
can be switched on by pressing av button twice.
The NAIT 5si volume control indicator will extinguish when
AV Bypass mode is engaged and the av input is selected.
Remote handset volume control and mute function will also
be disabled.
Note: The AV Bypass feature must be used with care. It
bypasses the NAIT 5si volume control leaving any signal
connected to the av input to be passed to the speakers at
full volume.
Note: Inserting a headphone plug while AV Bypass mode
is selected temporarily returns the NAIT 5si to normal
operation. Removing the headphone plug will return the
NAIT 5si to AV Bypass mode.
Note: The mute function is disabled when AV Bypass
mode is engaged.
14.3 Handset Volume Control
The remote handset volume keys provides 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 5si does not incorporate any facility for
channel balance adjustment.
14.4 Mute
Mute silences the outputs and can be selected or
deselected by pressing the remote handset mute key.
14.5 Display
The NAIT 5si 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.
14.6 Remote Control
The NARCOM 5 remote handset supplied with the
NAIT 5si duplicates all configuration and control functions.
See Section 15 for more information.
14.7 Defaults
To restore all NAIT 5si programmable settings to the factory
defaults press and hold the remote handset disp key while
the unit is in program mode. The NAIT 5si will exit from
program mode following this operation.
14.8 Fault Conditions
The NAIT 5si will indicate fault conditions by flashing front
panel button buttons. The following table lists the fault
indications.
