Executive mode (front panel security lockout)
The executive mode limits the operation of the Matrix 50 switcher from the front
panel. When the switcher is in executive mode, all of the front panel functions
are disabled except for the view-only mode functions. See Viewing a configuration
on page 3-7. Other than in view-only mode, if the user pushes a front panel
button when the switcher is in executive mode, that button's associated LED
flashes twice and goes out.
To toggle executive mode on or off, press and hold the Video and Audio buttons
for approximately two seconds. The Video and Audio LEDs blink twice to
indicate the mode change. Release the Video and Audio buttons. To toggle the
executive mode state again, press and hold the Video and Audio buttons again.
System reset to factory defaults
To reset the switcher to the factory default settings, press and hold the Esc button
on the front panel while AC power is being applied. Continue to hold the Esc
button until the power-up sequence is completed (all LEDs turn off, the Video and
Audio LEDs turn on, and the Esc LED blinks). System reset clears all ties and
presets, and sets all audio gain levels to unity gain (+0dB).
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 Matrix 50
Series switcher configurations. Cross off all unused or inactive inputs and
outputs. Use different colors for video and audio.
Worksheet example 1: System equipment
Figure 3-15 shows a worksheet for a 12x8 Matrix 50 switcher with audio in a
fictional organization with the system hardware annotated. Inputs 10 and 11
= off (value 0 dB),
= blinking (value 1dB),
= on (value 2dB)
