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.
