User Mode
For stand-alone MLS 100 Series switchers
If an MLS 100 Series switcher is used without a MediaLink
Controller, the User Mode screen, shown below, emulates the
MLS’s front panel input selection buttons and also provides a
means of volume control. See page 3-2 for details on basic
operation.
Special features
Audio/video breakaway switching — To switch the audio sig-
nal separately from the video signal, check the Audio
checkbox (at the right side of the I/O Switching area) and
uncheck the Video checkbox, then select an input. The
MLS switches to that input’s audio and leaves the previ-
ously selected video source active. Audio breakaway is
shown above: the video is from input 1 and the audio is
from input 2. (The corresponding SIS command is 1&2$.)
To switch the video signal without changing the audio
source, check the Video check box and
uncheck the Audio checkbox. See the
picture at left.
Selecting Mute selects input 0 (no input).
Volume Mute — Check this box (in the lower left corner) to
activate the audio mute (Amt) command. See
page 4-4 for the corresponding SIS command.
For MLS 100 Series switchers controlled by an MLC
If the MLS 100 Series switcher is connected to and controlled by
an MLC, the user mode screen will look something like what is
shown in the picture below.
In this case, you must set the volume control in
the Controller (MLC) Config section
to
“Switcher”, as shown at right.
