manufacturers’ products may interpret these codes differently and require you
to set these bits by “trial-and-error” until proper operation is achieved.
Consumer Format Advanced Settings (Emphasis): This status bit is used to
indicate if pre-emphasis has been applied to the outgoing digital audio signal.
The default is “
None
” and rarely will any user want to set the value to
“
50/15 µs
” unless the audio to be transmitted has been encoded with 50/15 µs
pre-emphasis.
Professional Format Advanced Settings (Data Type): The user may assign
the outgoing data as audio or non-audio data. Many devices ignore this
setting. The obvious default is “
audio
".
Professional Format Advanced Settings (Emphasis): The user may choose
to indicate or not if pre-emphasis has been applied to the outgoing digital
audio signal. The default is “
None
”, and rarely will any user want to set the
value to “
CCITT
” or “
50/15 µs
” unless the transmitted audio has been encoded
with one of those types of pre-emphasis.
Save, Delete, Load Buttons; H/W Installed
On the PC, at the rightmost side of the VX442 Control Panel are the
Save
,
Load
and
Delete
buttons as well as an “
H/W installed
” set of radio buttons.
These controls appear regardless of which VX442 Control Panel page is being
displayed.
SAVE, DELETE, LOAD
The VX442 Control Panel always retains the last settings entered. However,
the
Save
,
Delete
, and
Load
functions expand this capability to store different
sets of control panel settings using different configuration file names. These
configurations are then available for recall at a later date and time.
Clicking the ‘
Save’
button brings up a dialog box prompting you to name the
current configuration. Once you have done this, click ‘
OK’
, and your current
configuration has been saved to disk. If you decide that you do no longer need
a particular configuration, click the ‘
Delete’
button. Highlight the name of the
configuration file that you wish to delete, and click the ‘
OK’
button. To recall
or reload a saved configuration, click the ‘
Load’
button. Highlight the name of
the configuration file that you wish to recall, and click ‘
OK’
. Those settings
will now appear in the VX442 Control Panel and the driver will automatically
update the hardware.
