5.5.4 Auto restore function (X13)
The auto restore function of the channel selector can be
configured using solder spot X13 (see figure 5.9). The
auto restore function is intended for users that have a
fixed seating.
table 5.7: Solder spot X13
Solder spot Description
Open The auto restore function is
(default) disabled. When the system is
switched on and the channel
selector is activated, the default
volume and channel settings are
restored (channel: 0, volume:
-21 dB).
Closed The auto restore function is
enabled. When the system is
switched on or the channel
selector is activated, the last
known volume and channel
settings are restored.
Note
Any changes in channel or volume settings are
saved after 5 seconds.
Note
If the stored channel number is greater than the
maximum number of channels available, the
selector automatically chooses channel 0.
However, if the number of channel available is
increased and the stored channel number is less
or equal to the maximum numbers available and
if the channel control keys are not pressed in the
mean time, the channel selector immediately
switches to the stored channel.
Note
If the channel selector is used for recording
purposes, the X13 solder spot must be closed.
