The ‘bi-level’ reference signal long used for standard definition television is often used
for genlocking both SD and HD installations. However, if you are supplying an HD
reference signal to TalkShow’s Genlock input (and your other equipment), select the HD
(Tri-level) switch in the Reference Type area of the Genlock settings group.
This setting is applied when a genlock reference signal is not in use. To adjust the
setting, supply color bars to an input and pass TalkShow’s video output to a downstream
vectorscope. The vectorscope display is completely stable when Center Frequency is
properly adjusted.
TalkShow™ can optionally show Tally (On Air) indication to the remote Skype™ caller.
This feature is also enabled in the Setup pane.

Hint: The “Tally Overlay” menu in this control group allows you to use a custom On Air image if
you wish.
