Word clock settings
If a device such as a digital MTR or DAT recorder is digitally connected to the
AW4416, the clock that controls the timing at which digital audio is processed
(referred to as the “word clock”) must be synchronized. To do so, you must select
one of the devices as the word clock master, and set the remaining devices so
that they will follow the word clock supplied from the master device. Here we
will explain how to select the clock source to which the AW4416 will synchro-
nize.
Be aware that if the system includes an unsynchronized device, drop-outs and
click noise will occur.
1. Turn on the power of the external digital device and of the AW4416.
If an external device is connected to the SCSI connector of the AW4416, you
must turn on the power in the order of external SCSI device → AW4416. If the
power of the external SCSI device is off when you turn on the AW4416, it may
not start up correctly.
If the D.in Setup tab is not assigned to the [F4] key when you press the [SETUP]
key, press the [SHIFT] key + [F1] key to switch the tab, and then press the [F4]
key.
2. 2. Press the [SETUP] key → [F4] key.
The SETUP UP screen D.in Setup page will appear, allowing you to make word
clock settings.
In the WORD CLOCK SOURCE area of this screen you can select one of the fol-
lowing as the clock source to which the AW4416 will synchronize.
❍ SLOT 1 1/2–7/8
❍ SLOT 2 1/2–7/8
An input signal from a digital I/O card installed in OPTION I/O slot 1/2 will be
the clock source. You can select one pair from input channels 1/2–7/8 of the digi-
tal I/O card, and the AW4416 will synchronize to the word clock data included
in the input signal of the corresponding channel.
