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.
