Control Buttons And Leds; I/O Controls - Extron electronics MAV User Manual

Input 1 through 16 buttons and LEDs — The input buttons have two
1
independent functions: to select and identify an input and to select or
identify a preset. A more detailed explanation of the two functions is
included in Front panel operations, beginning on pages 3-4.
Output 1 through 16 buttons and LEDs — The output buttons and LEDs
2
select and identify outputs. As a secondary function on audio models, the
output LEDs also display the user-adjustable audio level of the selected input.
A more detailed explanation of the two functions is included in Front panel
operations, beginning on pages 3-4.

Control buttons and LEDs

Enter button — The Enter button saves changes when you set up a new
3
configuration. To create a simple configuration, specify video, audio, or both
[see I/O selection buttons (7) and (8)], press the desired input button (1), press
the desired output buttons (2), and press the Enter button.
Preset button and LED — The Preset button saves a configuration as a preset,
4
or recalls and makes active a previously-defined preset. The Preset LED
indicates save mode when it is blinking and recall mode when it lights
steadily.
View button and LED — The View button selects a view-only mode that
5
allows the display of the current configurations. The view-only mode helps
prevent changing configurations by accident. The View LED indicates that
the switcher is in view-only mode.
In view-only mode, pressing any input button (1) or output (2) button lights
the LEDs for the input and all outputs that are a part of that set of ties.
Pressing the button for any unassigned output lights only the LEDs for all of
the unassigned outputs. No input LED is lit.
As a secondary function on audio models, the View button decrements the
audio level of the selected input. In audio adjustment mode, the View LED
indicates a negative (-) attenuation value. A more detailed explanation of
audio level adjustment is included in Viewing and adjusting the audio level on
pages 3-11 through 3-14.
Esc button and LED — The Esc button cancels operations or selections in
6
progress and resets the front panel LEDs. The Esc button does not reset the
current configuration, the Video and Audio LEDs, any presets, or any audio
gain/attenuation settings. The Esc LED lights for two seconds after the Esc
button is pressed and released to indicate the escape function.
As a secondary function on audio models, the Esc button increments the
audio level of the selected input. In audio adjustment mode, the Esc LED
indicates a positive (+) gain value. A more detailed explanation of audio level
adjustment is included in Viewing and adjusting the audio level on pages 3-11
through 3-14.

I/O controls

When creating or viewing a configuration, you must specify whether the
configuration applies to video, audio, or both. This is done with the Video (7) and
Audio (8) buttons.
Although present, the Audio button has no function on video-only models.
Video button and LED — The Video button selects and deselects video for a
7
configuration that is being created or viewed. The Video LED lights to
indicate that video is available for configuring or for viewing.
