User Mode Screen

The User Mode screen, shown below, includes the most frequently used controls: it emulates the front panel for basic functions (input selection, volume control). See Front Panel Features and Operations on page 3-2 for details on basic functions.

Special features

Audio/video breakaway switching — To switch the audio signal separately from the video signal, select the Audio checkbox (at the right side of the I/O Switching area) and clear the Video checkbox, then select an input. The MLS switches to that input’s audio source while leaving the previously selected video source active. The picture above shows audio breakaway: video is from input 6 and audio from input 2.

To switch the video signal without changing the audio source, select the Video check box and clear the Audio checkbox.

Selecting Mute selects input 0 (no input).

Mixer on/off toggling — Click this button to toggle the Aux/Mix input on or off.

Volume Mute — Select this box (in the lower-left corner) to activate the audio mute (Amt) command.

Disable Switcher Front Panel — This feature (shown activated in the picture above) toggles executive mode 2 on or off to prevent or enable making any changes or selections via the MLS’s front panel. This feature can be enabled/ disabled via this software or SIS command 2X. You can also disable this feature by pressing and holding front panel buttons 1 and 4 simultaneously.

Disable Selecting Inputs at Switcher — Toggle this feature on to lock the front panel buttons; only volume control will be adjustable/selectable from the front panel. All other selections and adjustments can be made by IR remote control or via RS-232 (SIS command 1X or via this software). This button toggles executive mode 1 and is equivalent to pressing and holding front panel buttons 1 and 4.
