LS9-16/32 Owner’s Manual
“Word clock” is the clock data that provides the timing
basis for audio signals to be processed digitally.
If a digital I/O card installed in a slot is digitally con-
nected to an external device such as a DAW system, CD
player, or HDR (hard disk recorder), and you want digital
audio signals to be transmitted or received between the
LS9 and the external device, you must synchronize the
word clock of the respective devices.
In order for this to occur, one device must be the word
clock master (transmitting device) and the other device
must be the slave (receiving device), and the slave device
must synchronize to the master device.
If you want to set the LS9 as the word clock slave so that it
will synchronize to the word clock supplied from an exter-
nal device, you can either use the clock data included in
the digital audio signal received from a digital I/O card, or
provide dedicated word clock to the WORD CLOCK IN
jack located on the rear panel.
In either case, you must use the following procedure to
specify the word clock source that the LS9 will use for
operation.
