Digital Input/Output & Optional Card Settings
This section covers settings that apply to digital I/O and optional I/O cards.
Wordclock source selection and settings for Vari-pitch and cascade connection are made via the
DIO screen Setting page.
To call this page press the Work Navigate section [DIO]
key as many times as necessary, or press the [F1] key after
pressing the [DIO] key.
This page includes the following items.
1 WORDCLOCK SOURCE field
Selects the wordclock source to which the AW2400 will
synchronize. The condition of the received wordclock and
synchronization status are also displayed here.
B VARI field
Provides fine adjustment of the internal clock in order to
control the Vari-pitch function.
C STEREO BUS CASCADE field
Provides settings that allow an external device connected
to the [DIGITAL STEREO IN] connector to cascade-con-
nected to the AW2400 stereo bus.
“Wordclock” refers to the clock signal that provides the
basic timing for all digital audio signals. When transfer-
ring digital audio signals between the AW2400 and an
external device such as a computer-based DAW (Digital
Audio Workstation) or HDR (Hard-Disk Recorder) it is
necessary to ensure that both devices are synchronized to
the same wordclock signal. If the wordclock used by the
two devices is not perfectly synchronized the digital audio
cannot be accurately transferred and severe noise will
often be the result.
The normal procedure is to designate one device that will
be the source of the wordclock signal for the entire system
as the “wordclock master,” or simply “clock master”, and
all devices that receive and synchronize to the wordclock
master as “wordclock slaves”. The AW2400 can be set to
function either as the wordclock master or slave.
