Front panel security lockout (Executive mode)

To prevent unauthorized changes, when Executive mode is on it locks all functions except input selection functions and Program Audio Volume control. To toggle the Executive 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 fourth input button of the VGA/Audio group. The Exec Mode LED turns on to indicate that executive mode is on, off to indicate off. Release the Mode button when your selection has been made.

Program audio

Single Switcher mode

In Single Switcher mode, audio from the one selected input is routed to the program audio output.

Separate Switcher mode

In Separate Switcher mode, selected audio input from one of the three input groups is routed to the program audio output. The selected input and group is indicated by a flashing input LED. The LEDs of the two remaining, unselected groups (inputs) will be steadily lit.

To route a different audio input within the same input group to the program audio output, press one of the other input buttons within that group. The flashing LED moves to the new input. To route an audio input from a different group to the program audio, press the input button once if the input is already active and its LED is steadily on, or twice if the input is not active and its LED is off. The flashing LED moves to the new input within the new group.

Program audio breakaway

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

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 it is toggled 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.

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.
