Sample Clock Source
The Sample Clock setting determines the source of the HDR24/96 sample clock. If
the HDR24/96 is a clock master or not connected to any other digital device(s),
set it to
Internal . If the HDR24/96 is a word clock slave, set it to Word Clock . A
third option is Video and this is discussed in the Reference Manual.
Sample Rate
The Sample Rate determines how fast the HDR24/96 sample clock runs. Compact
Disks use a
44.1 kHz sample rate; the video production folks prefer 48 kHz
because their digital video recorders use 48 kHz.
Bit-Depth
The Bit Depth setting determines how many bits are contained in each audio
sample recorded to disk (the bit “resolution”). While
16-Bit audio takes up 1/3
less disk space than 24-Bit audio, 24-Bit audio offers the potential for greater
dynamic range (the difference between the softest and loudest sounds that can be
recorded) and captures a more accurate “image” of the sound.

don’t set it correctly,
the HDR24/96 time

wrong rate, even
though audio will play
at the right speed.
