Definitions

Tie — An input-to-output connection.

Set of ties — An input tied to 2 or more outputs.

Configuration — One or more ties or sets of ties.

Current configuration — The currently active configuration (also called configuration 0).

Global preset — A configuration that has been stored. One global preset can be assigned to each input button. When a global preset is retrieved from memory, it becomes the current configuration.

Front Panel Controls

Input and output buttons select inputs and outputs. Input and output LEDs light to indicate video and audio ties.

Input and output buttons also select presets.

Output buttons also toggle video and audio mutes on and off in View-Only mode.

Input LEDs also display the selected output’s volume.

Output LEDs also display the selected input’s audio level.

Enter button saves changes.

Preset button selects:

Save Preset mode to save a configuration as a preset.

Recall Preset mode to recall a previously- defined preset.

View button selects a view-only mode that prevents inadvertent configuration changes. The View button also decrements the level and volume. See Viewing and adjusting the audio level on QS-2.

Esc button cancels selections in progress and resets the front panel button indications. The Esc button does not reset: the current configuration, the RGBHV and audio selection, any presets, or any audio level or volume settings. The Esc button also increments the level and volume. See Viewing and adjusting the audio level on page QS-2.
