Input Naming
The DAC9 is pre-loaded with a selection
of names which can be assigned to the
five inputs of the converter, allowing for
easier identification of the various inputs.
When selected, the chosen input name will
display below the default name (USB, BNC,
etc.) on the normal operation screen.
To select an input name for any of the
inputs, press the ‘MENU’ button until
‘INPUT NAMING’ is displa
yed. Press the
‘OPTION’ button to select the desired
input for naming. Press ‘ENTER’ to engage
the naming utility, and use the ‘OPTION’
button to select the appropriate name
for the input. Press
‘ENTER’ a final time to
confirm the input name. The display will
show
‘OKAY’.
Auto Shutdown
The DAC9 is equipped with an auto
shut-off feature, designed to turn the
converter off after a period of time during
which it is not used. The auto shut-
off feature senses any interaction with
the converter, such as button presses,
remote usage, etc., but it is not designed
to sense whether a signal is present.
To change/disengage the auto shutdown
feature, press the ‘MENU’ button until
the ‘AUTO SHUTDOWN’ screen is
displayed. Pressing the ‘OPTION’ button
on the front panel or on the remote, the
DAC9 will scroll through the options
for ‘off’ (no auto shutdown), or 1 -8
hours. Once you have made a selection,
press ‘ENTER’ to confirm. The display
will show ‘OKAY’ before reverting back
to the normal operation screen.
Note
The auto shutdown feature is not in
the signal path of the converter and
has no deleterious sonic effect.
Tube Hours
The tube hours display shows the
accumulated time the DAC9 has been
powered on. This is useful for determining
the number of usage hours of the installed
vacuum tubes. See
A Note about Vacuum
Tubes on page 7 for specific information
regarding the tubes in the DAC9.
To reset the tube hours counter, press the
‘MENU’ button until ‘TUBE HOURS’ is
shown. Press the ‘OPTION’ button to
display ‘ENTER TO R ESET’. Press ‘ENTER’,
and the display will read ‘ENTER TO
CONFIRM’. A final press of the ‘ENTER’
button will reset the tube hour counter
to 0 and the display will show
‘OKAY’.
Note
Once the hour counter has been
reset, the total accumulated
hours cannot be recalled.
