Audio source
Three different audio sources (embedded, analog and S/PDIF) 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:
If only one input is selected (Analog or SPDIF or HDMI) than only this type of audio can
be placed on the output.
If the No audio (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.
Info: 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-Pro2 selects the first one (HDMI
embedded) immediately.
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
Status
Connection status of the selected input port is shown here. (Type of the video signal,
HDCP encryption, the source 5V, sync type)
Video signal info
Resolution, color depth and color space, Timing type and Timing ID of the incoming
signal are shown here.
The 'Timing type' and 'Timing ID' fields show which parameters are used to digitize the
incoming analog signal. The input port measures the incoming analog signal and
determines the timings. If the parameters need adjustment, it can be done on the right
side at 'analog options'. In this case, the 'Timing ID' field changes to 'user modified'
unless the parameters are not saved.
Audio signal info
Information about the embedded audio signal is shown here. (Signal present, audio type,
sampling frequency, channel allocation)
Analog audio input settings
Gain of analog audio input (amplify of the built in
preamplifier) signal can be adjusted as follows:
from 0 .. +24 dB with 3 dB steps
