SHl: FS (sampling frequency) selector
This switch selects the sampling frequency
when the unit operates in the internal sync
mode:
44.1 kHz (upper position)
44.056 kHz (lower position)
The selected sampling frequency is
indicated by the corresponding INT SAMPLING
FREQUENCY indicator on the front panel.
When the unit operates in the external sync
mode, the sampling frequency is determined
by the frequency of the external sync
signal input to the unit. Therefore, the
setting of this selector has no effect upon
the sampling frequency.
This selector is factory preset to 44.1
kHz.
