Mixer
The AB Mixer is an integral 2 input video switcher, which provides the
background video source to the program keyers, DSK1 and DSK2. The mixer
can be configured for cut, trans (variable fade transitions) or none (no option
illuminated). Pressing the Mixer button will toggle through the options.
Selecting the source
The Input router select buttons numbered Input 1-6 control the source into
the AB Mixer. The active source is identified with a brightly lit button whilst
the switched source is shown with a dimly lit button. The number of sources
available is dependant on the number of input cards fitted. To change the
switched source select one of the unlit buttons. When the Take button is
pressed the source will be swapped and the dim button will turn bright and
the bright button dim.

If cut is selected the AB Mixer is armed and the resultant transition is
previewed through the preview channel. When the Take button is pressed a
Cut AB transition is actioned and the video source will change on the
program output. The mixer will then be disarmed and the selected option set
to none (no option illuminated).
trans
If trans is selected the AB Mixer is armed and the resultant transition is
previewed through the preview channel. When the Take button is pressed a
Fade AB transition is actioned and the video source will change on the
program output. The mixer will then be disarmed and the selected option set
to none (no option illuminated).
