setting a maximum level You may also set a maximum volume level for the Nº383, a particularly
useful feature if the system is sometimes used by people who may not
be as careful as you yourself would be. (Teenaged children come to
mind.)
To change the maximum level, press setup to enter the setup menu,
turn the select knob until MaxVol = 73.2 shows in the display, and
then use the
volume knob to alter the maximum volume setting as
you see fit. When finished, press
enter to save your change. Pressing
setup one last time will return you to normal operation (leaving the
setup menu).
configuring
the DC trigger
You may wish to use the DC trigger output on the rear panel of the
Nº383 to turn on some other component automatically when the
Nº383 itself is on. If so, you have two trigger options: either a 12V
level
(constant) voltage that is present whenever the Nº383 is opera-
tional, and absent when the Nº383 is in standby; or a 5V pulse when-
ever the Nº383’s state is changed from one to the other (similar to the
output of a momentary contact switch). This menu item allows you to
choose which of these two options you want, given the needs of your
particular system.
If you are not sure what the receiving component needs for a trigger
signal, please ask your Mark Levinson dealer for assistance.
checking the
software version
The last item in the setup menu is a software version number that iden-
tifies what version of the Nº383 control software is running in the
preamplifier. Your dealer can inform you of the most current version of
this software, and you can compare that number to the one shown in
your display.
Although we do not anticipate frequent software updates for the Nº383
(after all, it does not have to contend with the ever-changing standards
for digital audio decoding), it has been designed to readily accept new
software should it become available. For example, if we were to add
some new convenience feature to the Nº383 at a future date, your
dealer could easily download the new software from our web site to his
computer, and from there to your unit, all without having to open the
product up. In fact, if the rear panel RS-232 port is accessible, you do
not even have to disconnect the preamplifier from the rest of the sys-
tem for such an update.
