"Intern" All audio clocks are generated internally. The selection of the sam-
pling rate is not affected by external signals.
"Aux In" The audio master clock is determined by the audio signal supplied at
the [AUX IN] socket, regardless of whether the sampling rate is sup-
ported by the video format selected in the HDMI generator or not.

nal.

Sample Freq
Selecting of the sampling rate of the generated audio data.
"Fixed frequen-
cies" The permissible scanning rates depend on the selected "audio for-
mat" and the video "Format Resol". For the audio format "PCM 8Ch
Lay1", the selected video "Format Resol" determines the permissible
sample frequencies - only they will be offered. For all other audio for-
mats, sample frequencies in the range from 30.72 kHz to 192 kHz are
available. The corresponding dependencies between video format
and supported sampling rates can be found in the HDMI 1.4 specifi-
cation under item 7.3.3 "Video Dependency".
"Value " Allows entering a "freely" selectable frequency within certain limits. At
this point, values that deviate by no more than 4% from a standard
sampling rate allowed for this video format are permissible.
