3-5 MAV Series Switchers • Operation
The current configuration and all presets are saved in non-volatile memory. When
power is applied, the last current configuration is retrieved. The previous presets
remain intact.
If an error occurs during the self-test, the switcher locks up and will not operate. If
your switcher locks up on power-up, call the Extron S
3 Sales & Technical Support
Hotline.
Creating a configuration
The current configuration can be changed using the front panel buttons. To change
the current configuration, do the following:
1 . Press the Esc button to clear any input LEDs, output LEDs, or control LEDs
that may be on.
2. Select to configure video, audio, or both by pressing the Video and/or Audio
buttons.
3. Select the desired input and output(s) by pressing the input and output
buttons.
4 . Press and release the Enter button.
5 . Repeat steps 1 through 4 to create additional ties until the desired
configuration is complete.
1. Only one video input and one audio input can be tied to an output.
2. If a tie is made between an input and an output, and the selected output
was previously tied to another input, the older tie is broken in favor of the
newer tie.
3. To indicate current ties, output LEDs light when an input is selected. To
clear unwanted outputs, press and release the associated output buttons.
4. If, when you configure video and audio ties, the Audio LED blinks and the
Video LED is on after you select an input or output, the LEDs indicate
audio breakaway: the audio ties are not the same as the video ties for that
input.
5. If an input with no tie is selected, only that input’s LED lights.
6. When the Video and Audio LEDs are on, if an input with an audio tie but
no video tie is selected, the input’s LED lights and the Audio LED blinks.
7. As each output is selected, the associated output LED blinks to indicate a
tentative tie. LEDs for output(s) that were already tied to the input light
steadily. Outputs that are already tied can be left on, along with new
blinking selections, or toggled off by pressing the associated output
button.
Example 1: Creating a set of video and audio ties
See figure 3-4 and the following steps for an example in which input 5 is tied to
outputs 3, 4, and 8.
This example assumes that there are no ties in the current configuration.
A
Press and release the Esc button. The Esc LED flashes once.
B
To select video and audio for the tie, if necessary, press and release the Video
and Audio buttons until the Video and Audio LEDs light.
C
Press and release the input 5 button. The input 5 LED lights.
