MAV Series Switchers 3 Chapter Three Operation Front Panel Controls and Indicators Front Panel Operations Troubleshooting Worksheets
Operation, cont’d Operation Front Panel Controls and Indicators The front panel controls (figure 3-1 and figure 3-2) are grouped into two sets. The input and output buttons and LED indicators are grouped on the left side of the control panel. The control buttons and I/O selection buttons and indicators are grouped on the right side of the panel. While the number of inputs and outputs varies depending on the size of the matrix, there are only two front panel arrangements.
1 2 Input 1 through 16 buttons and LEDs — The input buttons have two 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 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.
Operation, cont’d 8 Audio 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.
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 S3 Sales & Technical Support Hotline. Creating a configuration The current configuration can be changed using the front panel buttons.
Operation, cont’d Press and release the output 3, output 4, and output 8 buttons. The output 3, output 4, and output 8 LEDs blink to indicate a tentative tie. D The entire set of ties can be canceled at this point by pressing and releasing the Esc button. The Esc LED flashes once.
Press and release the Enter button. The input and output LEDs turn off. The current configuration is now video input 5 tied to video output 1, output 3, output 4, and output 8; and audio input 5 tied to audio output 3, output 4, and output 8. E Example 3: Removing a tie from a set of video and audio ties See figure 3-6 and figure 3-7 and the following steps for an example in which an existing audio tie is removed from the current configuration.
Operation, cont’d Viewing a configuration The current configuration can be viewed using the front panel buttons. The viewonly mode prevents inadvertent changes to the current configuration. View-only mode also provides a way to mute video and audio outputs (see Muting and unmuting video and/or audio in this chapter. To view 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. Press and release the View button. 3.

2. When you enter view-only mode, the output LEDs turn on for all outputs without ties. 3. When you mute video, the mute command mutes all video planes. 4. Mutes are not saved to non-volatile memory. When power is removed and restored, the mute settings are lost. Example 5: Muting and unmuting an output See figure 3-8, on page 3-9, and figure 3-12 and the following steps for an example of muting and unmuting several MAV switcher outputs.
Operation, cont’d Using presets The current configuration (configuration 0) can be saved as a preset in any one of 16 preset memory addresses. 1. Only the audio and video ties are stored and recalled; audio gain settings are not saved, and they do not change when a preset is recalled. 2. Presets cannot be viewed from the front panel unless recalled as the current configuration. Presets can be viewed using Extron’s Windowsbased control program. See Chapter 5 for more details. 3.
A Press and release the Esc button. The Esc LED flashes once. B Press and release the Preset button. The Preset LED lights. C Press and release the input 1 button. The input 1 LED lights for approximately 2 seconds and turns off. The Preset LED turns off. The configuration stored in memory location 1 is now the current configuration and can be viewed in the view-only mode (Example 4).
Operation, cont’d Example 8: Viewing and adjusting an audio level See figure 3-15 and figure 3-17 and the following steps for an example of viewing and adjusting the audio level. Audio gain and attenuation is displayed differently on the MAV 128 RCA (see the table below right) from the display on the MAV 168 and 1616, but the steps for displaying the value are the same.
LED key: = off (value 0 dB), 5 B = blinking (value 1dB), = on (value 2dB) Press C 1 2 3 C B 4 5 INPUTS 6 7 8 9 10 11 12 B CONTROL 1 2 3 4 5 OUTPUTS 6 7 8 I/O ENTER PRESET VIEW ESC VIDEO AUDIO C +8dB Figure 3-16 — +8dB displayed on MAV 128 RCA Press and release the View ( ) button once to decrease the audio level displayed by the output LEDs by 1dB.
Operation, cont’d If another input button is pressed and released, the level value for the current input is saved and the level value for the newly selected input is displayed. E Press and release the Audio button. The Audio LED stops blinking and the View ( ) LED (if lit), the Esc ( ) LED (if lit), the selected input LED, and all output LEDs turn off. Both the Video and Audio LEDs light.
Worksheets Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-17 and use one for each preset configuration. The forms accommodate all of the MAV models. Cross off all unused or inactive inputs and outputs. Use different colors for video and audio. Worksheet example 1: System equipment Figure 3-19 shows a worksheet for a MAV 1616 in a fictional organization with the system hardware annotated.
Operation, cont’d Worksheet example 2: Daily configuration Figure 3-20 shows a MAV 1616 switcher with 10 input devices tied to 14 output devices. Video and audio are shown as separate lines. This configuration has been assigned preset #3 with a title of “Daily Configuration” to indicate its use. 3 Figure 3-20 — Worksheet example 2: Daily configuration Worksheet example 3: Test configuration Figure 3-21 shows a switcher with an Extron VTG 200 video test pattern going to nine of the fifteen output devices.
