Word clock settings

"Word clock" is clock data that acts as the timing ref-
erence for digitally processing the audio data. If digi-
tal audio data is being transmitted or received
between the AW2816 and an external digital audio
device, each device must be using the same word
clock. Specifically, one device must be set to operate
as the "word clock master" (the device that transmits
word clock data), and the remaining devices must be
set to operate as "word clock slaves" (devices that fol-
low the word clock provided by the master).
If you are digitally connecting an external device such
as a digital MTR or sampler to the AW2816, select the
word clock master as described below.
• Be aware that if your system contains an unsynchro-
nized device, dropouts and click noise will occur.
• Even if an external device is not digitally connected,
a message of "WRONG WORD CLOCK!" will
appear if the word clock setting is inappropriate,
and it will not be possible to record correctly. Please
check the word clock settings as explained in the fol-
lowing procedure.

Press the [SETUP] key
The SETUP screen D.in Setup page will appear,
in which you can make word clock settings.
In the WORD CLOCK SOURCE area of this page,
you can select one of the following word clock
sources to which the AW2816 will synchronize.
• SLOT 1/2–7/8
The clock data included in the input signal of the
digital I/O card will be used as the word clock
source. You can select one pair of input channels
(1/2–7/8) from the digital I/O card, and the
AW2816 will synchronize to the clock data
included in that input signal.
• D.ST IN
The clock data included in the input signal of the
DIGITAL STEREO IN connector will be used as
the word clock source.

Operation section
• INT
Use the internal clock of the AW2816.
A button will be highlighted to indicate
that it has been selected as the current
word clock source.
An X superimposed on a button indi-
cates that no digital audio signal is
being input to the corresponding slot or
jack.
A diagonal line/superimposed on a but-
ton indicates that a digital audio signal
is being input to the corresponding slot
or jack, but is not synchronized to the
internal clock of the AW2816.
Buttons without an X or/indicate that a
digital audio signal is being input to the
corresponding slot or jack, and is syn-
chronized to the internal clock of the
AW2816.

In the WORD CLOCK SOURCE area, select
the desired clock source, and move the
cursor to the corresponding button.
The clock source you should select will depend
on the system in which you are using the
AW2816. Several typical examples are described
below.
• Using the AW2816 as the word clock master
If no digital audio device is connected to the
AW2816, or if you want the AW2816 to be the
word clock master that the other external devices
(e.g., digital MTR) will follow, turn on the INT
button. You should also use this setting when
recording from the AW2816's DIGITAL STEREO
OUT jack to a DAT recorder or MD recorder.
