Operation
Front Panel Controls and Indicators
The number of input and output buttons and LEDs that each MVX Series VGA
matrix switcher provides varies with the number of inputs and outputs.
Figure 3-1 shows the front panel of an 8-input, 8-output video and audio switcher.
Other switcher models but have fewer input and/or output buttons to
accommodate the different matrix sizes that they provide.
Many of the buttons and LEDs on figure 3-1 have dual functions.

Definitions
The following Extron matrix switcher terms are used throughout this manual:
Tie — An input-to-output connection
Set of ties — An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration — Consists of one or more ties or one or more sets of ties
Current configuration — The configuration that is currently active in the
switcher (also called configuration 0)
Global memory preset — A configuration that has been stored. Sixteen global
memory presets can be stored in memory. The input and output buttons
select preset memory locations to load or retrieve. When a preset is retrieved
from memory, it becomes the current configuration. On each model, there
are as many presets available from the front panel as there are input and
output buttons:
• The MVX 44 has 8 presets available on the front panel.
• The MVX 48 and MVX 84 have 12 presets available on the front panel.
• The MVX 88 has 16 presets available on the front panel.
On smaller MVX models, presets that are not available from the front panel
are still available under RS-232 or optional IR 501 control.
