Selecting the switching level (audio versions only)
The switcher has three different switching levels, selectable from the front panel;
level 1 is audio follows video, level 2 is video with no audio, and level 3 is audio
only. The currently selected level is indicated on the front panel by the video and
audio LEDs adjacent to the
Level Select button. If both the video and audio LEDs
are lit, the switcher is set for level 1 switching. If only the video LED is lit, the
switcher is set for level 2 switching. If only the audio LED is lit, the switcher is set
for level 3 switching.
Switching only affects the level(s) indicated. If level 2 is indicated, only the video
will be switched. If level 3 is indicated, only the audio will be switched.
To toggle between switching levels, press Level Select button repeatedly until the
desired level is indicated.
Reset to factory default
To restore input/output configurations, volume levels, and RS-232 settings to
factory default, press the
Input 1 and Input 5 buttons at the same time.
