In single switcher mode (default) the switcher emulates a single nine input switcher (9x1). In
this mode, when an input is selected from any group, the green LED indicator to the right of
the button lights, and the selected input (video and audio) is routed to the output for that
group. The selected audio is also connected to the program audio output. All other outputs,
(except program audio) are muted.

In the example, HDMI input 3 video and audio, (indicated by the blinking LED), is selected.
All other input LEDs are off. To select a different input, press the desired input button.
Input Selection — Separate Switcher Mode
There are four input selection groups on the front panel: VGA/YUV, DVI, HDMI and
(composite) Video. These groups correspond to the four independent A/V switchers (in
separate switcher mode) available.
Each input group has two (three for HDMI) numbered input selection buttons, allowing
selection from among the input sources in that group.
The output of each of the four groups is always active and the selected input audio/video
is available on each group’s output. Program audio output is taken from the most recently
selected input. That group (input) is indicated by a flashing LED, while the other groups are
indicated by solid LEDs. See Program Audio on page 15 for more details.
In the example below each group has an input selected. In addition, the blinking LED
indicates which input audio is also routed to the program audio output.
