Input selector buttons and LEDs for output 1 —
Press the
button corresponding to the desired input. The Input LED for
that input lights.

Input selector buttons and LEDs for output 2 —
Press the
button corresponding to the desired input. The Input LED for
that input lights.
When power is applied, the LEDs light sequentially from
left to right. For first time power up, the unit’s default
configuration is input 1 tied to both outputs 1 and 2, so
that the input 1 LEDs for both output 1 and for output 2
are lit. If this is not a first time power up, then the LEDs
corresponding to the last valid input selections light.
Tying input 0 to an output is done only using RS-232,
and it will be reflected on the front panel and any
optional MMX 32 AAP/MAAP installed. When a tie
is made between an input and an output, if that output
was previously tied to another input, the older tie is
broken when the new input is selected.
Audio breakaway is done by RS-232 through the Extron
Simple Instruction Set (SIS) or the Universal Switcher
Control Program, and the LED corresponding to the
audio source flashes during breakaway.

Front panel security lock out (executive mode)
Locking the front panel protects the switcher when it is installed
in location where unwanted tampering may occur. While the
switcher is locked, the user can select inputs only through a
remote device.
To lock the front panel, press the following buttons
simultaneously and hold them for at least three seconds:
• Input 1 button for output 1
• Input 3 button for output 2
The front panel LEDs flash to indicate that the front panel is
locked.
Repeat this procedure to unlock the front panel.
System reset
To clear all user settings and reset the switcher to its factory
settings, press and hold the input 3 button for output 1 while
you power up the switcher. Continue to hold the button while
the switcher lights the front panel LEDs sequentially from left to
right. The default settings are input 1 tied to both outputs, the
front panel is not locked, and all mute states are unmuted.
Audio switching
When you select an input by pressing a front panel selector
button, the audio and video signals from that input are routed
together to the appropriate output.
The MMX 32 VGA MTP also features audio breakaway through
the Extron Simple Instruction Set or the Extron Universal
Switcher Control Program (see chapter 3, Remote Control, for
details). When audio breakaway is active, the front panel LED
corresponding to the audio source flashes, while the LED
corresponding to the video source lights steadily.
