Names of Things and What They Do
7
LOCK indicator
This indicates whether correct synchronization to an external word clock is in effect.
8
Word-clock output/thru jack
This is a BNC connector for output of the internal clock (INTERNAL or SRC) or for
passing through an external word clock.
When synchronizing multiple SO-AES4 modules, use the included BNC cables to
connect the SO-AES4 modules to one another.
Shown below is an example of synchronization of multiple SO-AES4 modules to an
external word clock.
9
Word-clock output/thru switch (word-clock input terminal-resistor switch)
This switches the functioning of the word-clock OUT/THRU jack.
Also, when the SO-AES4 is functioning as a terminal for an external word clock,
setting the switch to OUT (75
Ω
ON) enables the terminal resistor and prevents signal
reflection.

When the SO-AES4 is
functioning as an external
word-clock terminal, set the
word-clock output/thru
(OUT/THRU) switch to “OUT
(75
Ω
ON).”
If the LOCK indicator flashes
and correct synchronization is
impossible, check the
connection with the word-
clock source device, its
sampling frequency, and the
like.
If the LOCK indicator is unlit
and synchronization is
impossible, check for a broken
cable and make sure the word-
clock source device is working
correctly.
The settings for the clock source and the sampling frequency are stored in memory
on the S-4000 unit.These settings are read automatically after a REAC link has been
established.
Operation using the S-4000R remote controller or the S-4000RCS remote-control
software is supported for storing and recalling of memory or scenes.
