Connection Example of Word Clock and
Audio
For digital audio output to be performed correctly, it is
necessary to connect a device incorporating a sampling
rate converter to the DIGITAL OUT 1/2/3/4 connector of
the receiver or input a master word clock signal to the
WORD SYNC IN connector of the receiver and perform
synchronization.
There are the following two types of system for inputting
a master word clock signal to perform synchronization.
If the number of connected devices is high, we do not
recommend cascade connections. We recommend using a
word clock divider.
Synchronization system example 1
This system connects the master word clock signal in
cascade via the WORD SYNC OUT connector of this
device.
Set the 75
Ω
termination switch of only the DWR-R02DN
unit at the end of the cascade connection to ON.
Synchronization system example 2
This system divides the master word clock signal with a
divider, and then connects to each device.
Set the 75
Ω
termination switches of all DWR-R02DN
units to ON.
Note
Master word clock
a) WORD SYNC IN
b) WORD SYNC OUT
c) Set the 75
Ω
termination switch to OFF
d) Set the 75
Ω
termination switch to ON
