DVDO iScan Mini - 4K Scaler / Video Enhancement
DVDO iScan Mini 24
Audio Output to S/PDIF
If there is a need to extract audio from the HDMI stream and output to S/PDIF instead (e.g. Soundbar, DVI only TV, or
whole home audio feed), the iScan Mini optical S/PDIF audio output can be used.
Note that while iScan Mini does not have an audio processor, the Audio menu does allow you to modify the audio part of
the EDID so that the proper audio for your application can be requested from the source.
Auto Mode makes no modification to the audio portion of the
EDID presented by the attached display. Since most displays
only have stereo PCM in their audio EDID, That is what the
source will send. If you connect the optical S/PDIF to an AVR or
soundbar, only stereo audio will be heard. Also, if the TV asks
for True-HD audio (incompatible with S/PDIF) there will be no
output from the optical S/PDIF output.
Custom mode allows you to select a specific audio format to
request from the source. When activated, the audio portion of
the EDID from the TV is completely removed and replaced with
the selection in the next menu.
Custom S/PDIF can be selected to be PCM/2, meaning stereo
PCM only or you can select AVR which applies a full selection of audio formats that most AVRs and soundbars are
capable of decoding.
AVR selection includes AC-3/DTS 5.1 and 2 channel PCM
