Examples
Example 1: Using Set, Down and Up to adjust
LTC Gain
As an example, the following steps explain
using the USD front panel controls to
change the Linear Time Code output level.
LTC Gain is the example parameter, but
the basic steps are similar for most parame-
ters.
To select a parameter name and change its
respective parameter values:
1
Time code numbers should be visible and
not blinking in the LED Time Code Dis-
play. If you don’t see them, press the Set
switch until you do.
2
Press the Set switch. The LED Time Code
Display will switch from showing time
code numbers to a parameter name. The
first name is Set Generator (SE7 6En), al-
though you may see a different name, de-
pending upon the USD’s last settings.
