Extron electronic Multi-Graphic Processor MGP 464 Manual De Usuario

The MGP 464 front panel contains four Window Select buttons.  Use these buttons 

in conjunction with the Input buttons to specify which window displays an input, 

or use them with the picture control buttons to specify which window/image is 

adjusted.  
When you select a picture control, the window whose button was previously 

selected is affected.  (See “Picture Controls,” later in this chapter, for information on 

the available controls.)
To select a window, press its Window Select button, which lights.  To deselect a 

window, press another Window Select button.

The MGP 464 front panel contains a set of four input buttons that enable you to 

select RGB, HD, and/or video (component, S-video, or composite) inputs for 

windows 1 through 4.  It also contains 15 virtual input buttons that enable you to 

select only video inputs. 

Before you can select an input, you must first select a window, as follows:

. 

Press the Window Select button for the window in which you want the input 

to be displayed.

. 

Press the button with the number of the input you want to display.

  If you have a computer connected to input 1 and you want to display 

the computer’s output in window 4, press Window Select button 4, then press Input 

button 1.

To mute a selected input (turn off its signal and close the window), press its button 

again.  The button’s backlight blinks continuously, which indicates that the input is 

muted.
When an input is muted or unmuted, the currently selected transition effect (cut, 

wipe, or dissolve) is used to close or open the window on the output display.   See 

“Window effects submenu” in the “Window Configuration menu” section, later in 

this chapter, for information on transition effects.   
To unmute the input, press its button again.  The button’s backlight stops flashing 

and returns to a steady light.
