Digital Input/Output & Optional Card Settings

1 INT button
When this button is on the AW2400’s internal clock is
selected as the wordclock source. Use this setting
when using the AW2400 on it’s own, or when using
the AW2400 as the wordclock master for other
devices.
B D.ST IN button
When this button is turned on the clock signal
included in the digital audio signal received at the
[DIGITAL STEREO IN] connector is used as the
wordclock source.
Use this setting when you want the AW2400 to func-
tion as a wordclock slave that synchronizes to the sig-
nal received via the [DIGITAL STEREO IN]
connector. Choose this setting when, for example, you
will be cascade-connecting the digital audio from an
external device to the AW2400 stereo bus, or when
receiving digital audio from a DAT recorder or similar
digital audio source.
C 1/2–15/16 buttons
When one of these buttons is turned on the clock sig-
nal included in the corresponding digital audio signal
received via the rear-panel slot is used as the word-
clock source (i.e. the clock signal included in one ste-
reo pair: 1/2, 3/4–15/16).
Use one of these settings when using an external HDR
or other digital audio source as the wordclock master
to which the AW2400 will be synchronized as the
wordclock slave.
The CLOCK and SYNC rows show the condition of
the received wordclock signal and the synchronization
status, respectively.
• CLOCK ... A “●” symbol will appear when an appro-
priate wordclock signal is detected.
• SYNC...... A “●” symbol will appear when the
AW2400 is properly synchronized to the
incoming wordclock signal. A “ ” symbol
will appear when an appropriate word-
clock signal is not detected.
D SLOT
When an I/O card is installed in the rear-panel slot a
graphic symbol that indicates the type of card will
appear here. “NO CARD” will appear when no card is
installed.
E IN, OUT
Indicates the number of input channels (IN) and output
channels (OUT) available on an I/O card installed in
the rear-panel slot.
F Fs
Indicates the sampling frequency of the wordclock
signal currently selected as the wordclock source.
• When the internal clock is selected the sampling frequency of
the current song becomes the sampling frequency for the
entire system.
HINT
• Buttons that appear gray indicate that an appropriate digital
signal is not available at the corresponding connector or slot,
and cannot be used.
NOTE
• When using the AW2400 as wordclock slave, check that the
sampling frequency of the current song matches the sampling
frequency shown in the Fs filed. For example, a song that was
recorded with a sampling frequency of 44.1 kHz will play back
with the wrong pitch and tempo if slaved to a 48 kHz word-
clock signal.
• “Unlock” in the Fs field indicates that proper synchronization
with the wordclock source has not been achieved. In such
cases check that an appropriate wordclock signal has been
selected as the source.
