Reload factory defaults
Current input: Reloads the default values to the currently selected input.
All inputs: Loads the factory default values to all inputs.
Cable equalization
The amplitude of high frequency signals decreases after they pass through long distances
in copper cables. To counter-act this phenomenon, input port can amplify the digital signal
while maximizing the amplitude at a certain level, which is defined by the DVI 1.0 standard.
This process is called equalization. The digital inputs are automatically compensated for
up to 30-meter cable length.
General settings
Video Source
The signal type of the connected source can be selected in this drop down list: Analog
RGB, Analog YUV, Analog auto, Digital, and Auto source. The Analog auto setting
determines the color space of the connected analog video signal automatically. The Auto
source setting accepts both digital and analog signals on the input and selects the one
which is first detected.
Info If the source signal type is unknown the recomended interface setting is the Auto.
HDCP enable
The HDCP capability can be enabled or disabled on the input port with using the HDCP
enable checkbox. This can prevent unnecessary HDCP encryption with certain source
devices. Note that only unprotected content can be played on the source if this setting is
disabled. For more information about HDCP handling see section 2.6 on page 14.
No sync color
The port generates a solid 640x480 resolution image when there is no incoming signal.
The color of this picture can be set here. Double click on the colored field, a new window
will appear. Choose the desired color then click the 'OK' button to apply changes. Click the
Cancel button to discard changes and close the window.
Audio source
Three different audio sources can be connected to one input port at the same time. The
'Audio source' parameter selects which incoming audio signal will be placed on the selected
output port. Select the desired option from the 'Audio source' drop down list:

The audio source settings can be:
Mute, HDMI, Analog, SPDIF
Auto (HDMI, Analog), Auto (SPDIF, Analog)
Auto (HDMI, SPDIF, Analog), Auto (SPDIF, HDMI, Analog)
If only one input is selected (Analog or SPDIF or HDMI) than only this type of audio
can be placed on the output.
If Mute is selected than the matrix ignores the audio input signals.
Every AUTO value has a priority order. The matrix checks the first item of the priority
list. If there is a valid audio signal on that audio input the signal will be placed on the
outputs. If there isn't the matrix checks the second item of the priority list. And so on.
If the second item of the priority list was selected (e.g. SPDIF) and the first item (e.g.
HDMI embedded) appears on the input UMX4x4-Pro selects the first one ( HDMI
embedded) immediately.
