Front Panel Controls and Indicators

The front panel controls (figure 3-1) are grouped into four sets. The input and output buttons are grouped on the left side of the control panel. The control buttons are grouped in the middle of the panel. On the TPX 88 A only, the input/ output (I/O) selection button and audio controls are grouped on the right side of the panel.

The TPX 88 is identical to the TPX 88 A, with the exception that it does not have I/O selection or audio controls. These controls are marked with an asterisk (*) in figure 3-1.

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 ties 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 and output buttons

The large, illuminated input and output pushbuttons can be labeled with text and/ or graphics. The buttons can be set to provide amber background illumination all the time or the background illumination can be set off. The buttons blink or are fully illuminated (depending on the operation) when selected.

Input 1 through 8 buttons — The input buttons have three independent functions: to select an input, to identify the selected inputs, and to select a preset. A more detailed explanation of these functions is included in Operations, beginning on page 3-5.

Output 1 through 8 buttons — The output buttons have four independent functions: to select an output, to identify the selected outputs, to select a preset, and (on the TPX 88 A) to display the user-adjustable audio level of the selected input. A more detailed explanation of these functions is included in Operations, beginning on page 3-5.
