Word Sync; Up Convert - Esoteric SA-60 Owner's Manual

Word sync

This feature is used when you want to get your whole system
locked to a single sync signal (clock) by connecting this unit to
the Esoteric AZ-1, G-0/G-0s or other devices that are capable
of outputting a sync signal (word clock).
Use the WORD button to switch between Word ON and
Word OFF.
The main unit can accept and synchronize to the following
frequencies received from external devices:
44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz
This unit also accepts a Universal Clock frequency of 100 kHz.
< It takes several seconds for the unit to detect and lock to an
external clock.
< Make WORD SYNC connections before powering on the unit.
If no valid word sync signal is received, the display shows "No
Word!".

Up convert

Press the UP CONVERT button to select algorithms for upward
conversion. A lit indicator shows the current selection.
FIR
An FIR-type digital filter that does upward sample rate
conversion.
You can select Wide or Narrow characteristic for this filter.
See page 20 for details.
RDOT+FIR
This provides a combined function of FIR and RDOT filters.
The RDOT filter has a slow roll-off characteristic and provides
a smooth immersive sound.
The two up-conversion filters are directly coupled digitally so
that the best of each is brought out.
PCM q DSD
The SA-60 can convert PCM signals to the DSD signals (1 bit,
64 fs) that are used on a Super Audio CD.
< The conversion has effect on signals output from the
following terminals:
XLR (BALANCED) L and R
AUDIO OUT (L and R)
AUDIO OUT (FRONT L and R)
Other terminals cannot output upconverted or DSD-converted
signals.
< Super Audio CDs output a DSD signal (1 bit, 64fs) and cannot
be up converted.
< The DSD indicator lights during playback of a Super Audio
CD.
