Figure 3-4— +8dB gain on input #1 displayed
B
Press and release an input button to select an input.
C
Press and release the Decrement ( ) or Increment ( ) button to decrease or
increase the audio input level until the Inputs 1 and 2 LEDs are lit and the
Input 3 LED is blinking rapidly and the Video/+dB LED is on. This indicates
a gain of +8dB.
D
Press and hold the Conf/Save button until the I/O LED turns off to save the
attenuation or gain value in memory and exit the audio adjustment mode.
If another input button is pressed and released, the level value for the current
input is saved and level value for the newly selected input is displayed.
System reset to factory defaults
To reset the switcher to the factory default settings, press and hold the Conf/Save
button on the front panel while AC power is being applied. Continue to hold the
Conf/Save button until the power up sequence is completed (all LEDs turn off, the
Output 1, Video, and Audio LEDs turn on, then the Conf/Save LED blinks).
System reset clears all ties and sets all audio gain levels to unity gain (+0dB).
Executive mode (front panel security lockout)
The executive mode limits the operation of the CrossPoint switcher from the front
panel. When the switcher is in executive mode, all of the front panel functions are
disabled and the ties can be viewed but not changed. See the section on Viewing the
current configuration earlier in this chapter. Selecting an Output will show
associated Input and the Conf/Save button selects the signal type (Audio, Video, or
both). Other than that, if the user pushes a front panel button when the switcher is
in executive mode, the Conf/Save LED blinks three times and goes out.
To toggle executive mode on or off, press and hold the Outputs and Conf/Save
buttons for approximately five seconds. The Conf/Save LED blinks to indicate the
mode change. Release the Outputs and Conf/Save buttons. To toggle the
executive mode state again, press and hold the Outputs and Conf/Save buttons
again.
