Program audio breakaway

Separate Switcher mode provides audio breakaway by allowing you to route the audio signal from any input group to the program audio output, independently from the video signal.

For units with firmware version 1.10 and above:

To select an input for program audio breakaway, first set the Follow sub-mode off. (See the instructions under Follow sub-mode below.) Press and hold the Program Audio Mute button, then press and release the input button corresponding to the desired audio source. The LED of the input you just selected flashes to indicate that it is the input for program audio.

The newly selected input’s LED flashes, indicating that it is the source for (breakaway) program audio.

Follow sub-mode

Within the Separate Switcher mode there is a special sub-mode called Follow sub-mode. With the Follow sub-mode off (default), the switcher functions as described above. With the Follow sub-mode on, when any input button is pressed once, the input is routed to program audio.

To toggle the Follow sub-mode on or off, press and hold the Mode button for more than 2 seconds until the front panel LEDs change to view mode, then press and release the first button of the S-video/Audio group. S-video/Audio input #1 turns on to indicate that Follow sub-mode is toggled on, or it turns off to indicate that Follow sub-mode is off. Release the Mode button when your selection has been made (the LED resumes input indication).

Program audio volume

Use the Program Audio Volume control knob to adjust the volume of the program audio output. When the volume control knob is turned, the volume increases at a rate of 1 dB per step of the digital potentiometer. Program audio volume does not affect mic volume. Program audio volume has a range of 0 to 100.

Reset program audio volume

To reset the program audio volume to the default level (70), press and hold the Mode button, then press and release the second button (labeled Prog Vol. Reset) of the Video/Audio group within 2 seconds. Release the Mode button when the volume has been reset.
