section labeled AUDIO. A red LED will light
above the left corner of the selected button,
indicating that the switch has been made. On
the rear panel, a red LED for the audio channel
should also indicate the selected input.
4.2 RGBHV+AUDIO MODE BUTTON
When this button is selected, the audio channels
will be ”slaved” to the ”master” RGBHV. In other
words, when you select an RGBHV source, the
same audio input will switch with the RGBHV
source. Note that the audio channels may still be
switched separately, using the buttons in the
AUDIO section of the front panel control.
4.3 VIDEO+AUDIO MODE BUTTON
When this button is selected, the audio channels
will be slaved to the master VIDEO. When you
select a VIDEO source, the same audio input will
switch with the VIDEO source. Note that the audio
channels may still be switched separately, using
the buttons in the AUDIO section of the front panel
control.
Note: In normal operating mode with the
RGBHV+AUDIO and the VIDEO+AUDIO
buttons turned OFF, the MX2222AT will
allow complete independent control over
the RGBHV, video, and audio sources
through the front panel. For example, if
Input 1 is selected for RGBHV, Input 1 or
2 may be selected for video or audio
sources.
4.4 RGBHV+VIDEO+AUDIO FEATURE
When both the RGBHV+AUDIO and the
VIDEO+AUDIO buttons are selected
simultaneously, the audio input will follow either
RGBHV switching or VIDEO switching. In this
mode, RGBHV will act as a ”master” to the VIDEO
as well (e.g. if RGBHV switches both, the VIDEO
and AUDIO will follow).
4.5 STAND-BY BUTTON/ALL INPUTS OFF
When selected, this button will put all inputs into a
stand-by mode with no inputs active. This affects
RGBHV, VIDEO, and AUDIO simultaneously. All
LED’s in the input select section of the front panel
should turn off. It does not affect the power mode of
the switcher. This mode is used when a user
wishes to have none of the inputs selected.
The STAND-BY button is also used to RESET the
switcher to factory defaults. This is done using the
following procedure:
1. Turn OFF or disconnect power to the
MX2222AT.
2. Press and hold the STAND-BY button.
3. While holding this button, reconnect the power.
The MX2222AT will respond with a beeping noise.
You may also hear the relays resetting internally.
This will reset all previous settings.
Note: If the MX2222AT is set for auto
switching, only the channels that are not
set for auto switching will go into stand-by-
mode.
4.6 SYNC DELAY MODE BUTTON
The Sync Delay feature is offered as an option for
the MX2222AT. If this feature has not been
installed, pressing the SYNC DELAY button will
have no affect on the switcher.
If the SYNC DELAY feature is already installed,
enable sync delay switching by pressing and
holding this button for approximately 3 seconds
until a beeping sound is heard. SYNC DELAY
switching will only affect the horizontal and vertical
channels, thus it may only be used for RGBS and
RGBHV signal formats. The SYNC DELAY feature
offers a 0.5 second delay between the
disconnection of the outgoing video and the
reconnection of the incoming video (the sync is
switched off-screen during this delay).
