3-3 CrossPoint 42 HVA Matrix Switcher • Operation
explanation of audio level adjustment is included in Viewing and adjusting the
audio level later in this chapter.
6 Audio/-dB LED — The Conf/Save button selects and deselects audio for a
configuration being created or viewed. The Audio/-dB LED lights to indicate
that audio is available for configuration or viewing. The Audio/-dB LED
lights steadily to indicate that the audio follows the video configuration. The
Audio/-dB LED (and the LED for the selected audio input) blink to indicate
that the audio configuration is broken away from the video configuration. In
audio level display/adjust mode this LED indicates attenuation (-) of the
audio level.
7 Video/+dB LED — The Conf/Save button selects and deselects video for a
configuration being created or viewed. The Video/+dB LED lights to indicate
that video is available for configuration or viewing. In audio level display/
adjust mode this LED indicates a gain (+) in the audio level.
Front Panel Operations
The following paragraphs detail the power-up process and then provide sample
procedures for creating ties and configurations; changing a configuration; viewing
ties and configurations; and viewing and adjusting the audio level.
Power
Power is automatically applied when the power cord is connected to an AC source.
When AC power is applied, the switcher performs a self-test that blinks the front
panel LEDs during the test. An error-free power up self-test sequence leaves the
RGBHV LED, Audio LED, Output 1 LED, and Input 1 LED on and all other LEDs off.
During the first power up, Input 1 is tied to Output 1, so both LEDs will
light. During subsequent power ups, the LED for the input that is tied to
Output 1 will light.
The current configuration is saved in non-volatile memory. When power is
applied, the last current configuration is retrieved.
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

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 Conf/Save button to select video, audio, or both for configuration.
2. Select the desired output by pressing and releasing the Outputs button to
cycle through output 1 or output 2.
3. Select the desired input by pressing and releasing the appropriate Input
button.
4. Repeat steps 1 through 3 to create a second tie, as desired.
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, input LEDs light when an output is selected.
