Operation

Front Panel Controls and Indicators

The number of input and output buttons and LEDs and other controls and LEDs
that are present on each MAV Series AV matrix switcher vary with the number of
inputs and outputs and whether the switcher has video only or both video and
audio. Not every switcher has every control or indicator described in this chapter.

In the following descriptions, you will find the following terms:

•

Video-only switcher

— Switches S-video or composite video only and has no

audio capabilities.

•

Audio/video switcher

— Switches either S-video or composite video and

audio.

Figure 3-1 shows the front panel of an 8-input, 8-output video-only switcher.
Figure 3-2 shows the front panel of a 4-input, 8-output video and audio switcher.
These examples show all of the control and indicator combinations that you may
encounter with your particular switcher.

Many of the buttons and LEDs on figure 3-2 have dual functions.
