Analog Audio Options
DIFFERENCE:
The
-A
suffix in the model name refers to the analog audio option
(for more information
table).
▪
An external audio signal can be embedded in the HDMI stream by the Analog Audio input port. In this
case the audio from the analog input port is converted and embedded in the HDMI stream. Furthermore,
the Analog audio output ports allow to de-embed the audio of the HDMI output stream. Please note that
only stereo LPCM can be de-embedded from the HDMI signal.
The test pattern generator feature makes possible to transmit the analog audio without any video signal.

DisplayPort Video Options
DIFFERENCE:
DisplayPort inputs are available
in certain models,
-D
letter the model name refers to that
(see the
table).

▪
If the emulated EDID does not support the deep color signal (10, 12-bit), and the incoming video is
deep colored, then the video processor converts the signal to 8-bit automatically. The compatible
color depths can be checked in the
in
Software Control – Lightware Device Controller
software.
▪
The factory default EDID (F49 - 1920x1080p60.00Hz) has deep color support up to the full HD
resolution. When the resolution of the incoming video signal is more than the full HD with deep color
(e.g. 4K@30Hz with 10-bit or 12-bit), the color depth is reduced to 8-bit.
▪
If the signal is 4K@30Hz with 10-bit or 12-bit, using F146 EDID (3840x2160@60Hz with deep color
support) is highly recommended.
▪
DisplayPort signals over 18Gbps will be converted down by either truncating bit depth or by converting
RGB signal to YCbCr 4:2:2 12-bit signal based on user selection. The second option will not reduce the
color depth rather, it results in loss of chroma information.
▪
The video processor converts the DisplayPort video signal to HDMI in all models.
