3.4 Extracting Audio
The SC-HDMI-2A can extract audio from the
HDMI™ source
input and simultaneously output to analog and digital S/PDIF
audio out.
Note that the extracted
HDMI™ audio may lead the video as it
appears on the display by several milliseconds. This is due to
added latency due to processing of video that occurs in the
display. The SC-HDMI-2A can correct for this with a built-in audio
delay of 40ms, 110ms, or 150ms. If a different delay time is
needed then we recommend using the Hall Research Universal
Audio Delay Processor (AD-340) which is capable of delaying
digital or analog audio for any amount of time up to 510ms.
3.5 Embedding Audio
The SC-HDMI-2A can embed audio into the
HDMI™ output
stream. To embed audio you must pull up the OSD menu,
navigate to the AUDIO menu item, and change the source to
wherever you want audio to come from: HDMI, L/R (analog
stereo), or OPTICAL (digital S/PDIF).
Note that embedding audio does require a display. If no display is
connected then the
HDMI™ source will not output a stream.
3.6 Factory Defaults
There are two ways to reset the unit back to its factory default
configuration.
1. If you are able to access the OSD menu you can select
the option from the main menu.
2. You can also set the device back to factory defaults by
pressing and holding the MENU button while connecting
the power supply.
