Front Panel Controls and Indicators

The front panel controls (figure 3-1 and figure 3-2) are grouped into two sets. The input and output buttons and LED indicators are grouped on the left side of the control panel. The control buttons and I/O selection buttons and indicators are grouped on the right side of the panel.

While the number of inputs and outputs varies depending on the size of the matrix, there are only two front panel arrangements. The MAV 168 and MAV 1616 have 16 input buttons and 16 output buttons (figure 3-1). The MAV 128 has 12 input buttons and 8 output buttons (figure 3-2).

Definitions

The following terms, which apply to Extron matrix switchers, 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 tie or one or more sets of ties.

Current configuration — The configuration that is currently being used (also called configuration 0).

Global memory preset — A configuration that has been stored. Up to sixteen global memory presets can be stored in memory. The input buttons select the desired preset memory location to load or retrieve a preset. When a preset is retrieved from memory, it becomes the current configuration. One preset can be assigned to each input button.

Input buttons, output buttons, and LEDs

If the switcher has fewer outputs than output buttons and LEDs, only the applicable buttons and LEDs perform the function of selecting and identifying an output.
