Operation, cont’d

8Audio button and LED — The Audio button selects and deselects audio for a configuration that is being created or viewed. The Audio LED lights to indicate that the audio configuration follows the video configuration. The Audio LED blinks to indicate that the audio configuration is broken away from the video configuration.

As a secondary function on audio models, the Audio button selects the audio level display/adjustment mode. Press and hold the Audio button until the Audio LED begins to blink. If the Video LED was lit, it turns off. Select an input. The current audio level setting for the selected input is displayed by the output LEDs. The audio level for the selected input can be increased and decreased by pressing the View (5) and Esc (6) buttons. A more detailed explanation of audio level adjustment is included in Viewing and adjusting the audio level on pages 3-11 through 3-14.

Front panel I/O label windows

9Input and output label windows — These translucent panels can be removed and replaced to insert labels behind the panels. To remove a panel, insert the Phillips-head end of an Extron tweaker or small Phillips-head screwdriver into the hole in one end of the panel, and gently slide the tab on the edge of the panel out of the recess in the switcher housing.

Input and output labels can be created easily with Extron’s Button Label Generator software, which ships with every Extron Matrix Switcher, or with any Brother P-Touch labeler. Each input and output can be labeled with names, alphanumeric characters, or even color bitmaps for easy and intuitive input and output selection (figure 3-3). See Chapter 5, Matrix Software, for details on using the label software.

Front Panel Operations

The following paragraphs detail the power up process and provide sample procedures for creating ties, sets of ties, and configurations; changing a configuration; viewing ties, sets of ties, and configurations; muting and unmuting the video and audio; saving a preset; recalling a preset; and viewing and adjusting the audio level.

Power

On all models, 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 video and/or the Audio LED(s) on, depending on the model, and all other LEDs off.
