Program Audio Selection

Program Audio

The selected audio input is routed to the program audio output according to the switcher mode. The input LED selected for program audio output blinks.

Single switcher mode

In single switcher mode, audio from the selected input is routed to the program audio output. If combine mode is active, when a DVI input is selected, DVI audio is available on the HDMI audio output and the program audio output.

Separate switcher mode

In separate switcher mode, the selected audio input from only one of the four input groups is routed to the program audio output. The selected input is indicated by a flashing input LED and is always the last input selected. The selected input LEDs of the other three groups are steadily lit.

If combine mode is active, when a DVI input is selected, DVI audio is available on the HDMI audio output and the program audio output.
