3.9.3. Crosspoint Modes
The audio crosspoint settings can be controlled by any of the following ways:
▪ Using the LCD menu by pressing the navigation buttons (see in Crosspoint Settings Menu section);
▪ Using the Lightware Device Controller (LDC) (see The Layout of the Crosspoint Menu section);
▪ Sending LW3 protocol commands (see Video Port and Crosspoint Settings section), or
▪ Using the
Autoselect
function, see in The Autoselect Feature section.
3.9.4. Audio Options - Example
ATTENTION! The following drawing is a random example and may not cover all capabilities. The received
and transmitted signals depend on the configuration of your MODEX device.
The Concept
Two sources are connected to the MODEX transmitter: a Blu-ray player which sends video and embedded
audio signals on HDMI; and a media player which sends audio signals to or receives audio signals from the
transmitter. The MODEX receiver accepts the signal on the OPTS/OPTM line. On the MODEX receiver side
there are two sinks: an audio amplifier that can accept and send analog audio and a HD TV that can accept
digital audio signal. A microphone is also connected to the audio amplifier. The transmitted audio signal
depends on the settings of the transmitter and receiver sides.
Three options are available for the audio module both on the RX and TX side:
▪
Analog
: only analog audio signal will be transmitted.
▪
Digital
: only digital audio signal will be transmitted.
▪
Mixed
: both analog and digital audio signals can be transmitted, see available connections in the next
section.
The following scenarios are supported for the audio presentation:
▪
Digital audio signal from the
Blu-ray player
is transmitted to the digital sink device (
HD TV
) and analog
audio signal from the
Media player
is transmitted to the analog sink device (
Audio amplifier
) through the
fiber optical line.
▪
Digital audio signal from the
Blu-ray player
is transmitted to the analog sink device (
Audio amplifier
) and
analog audio signal from the
Media player
is transmitted to the digital sink device (
HD TV
).

▪ Digital audio signal from the
Microphone
is transmitted to the
Media player
as a "reverse direction"
through the fiber optical line.
3.9.5. Mixed Audio Mode
The mixed audio mode allows to embed and de-embed analog and digital audio signals as well but the
available connections in the crosspoint are limited. Compared with the analog and digital audio modes the
crosspoint possibilities are the same so there is no transition between the analog and digital inputs and
outputs in the case of analog/digital audio interface modules.
Affected Interface Modules:
▪
MODEX-IF-AUDIN
▪
MODEX-IF-AUDOUT
▪
MODEX-IF-AUD
The following drawing shows all audio layers in the MODEX transmitter and receiver:
Audio Layers
The three audio layers, between the transmitter and the receiver are defined and fixed, always extended. The
other audio inputs and outputs are optional and depend on the installed interface modules; the available
crosspoint settings depend on the application mode set in the properties of the audio module.
