CLOCK SOURCE

CLOCK SOURCE selects the master clock timing reference for the ADA-7000. This
parameter interacts with the VS-2480’s MASTER CLOCK parameter (Page 132).
• When the VS-2480’s MASTER CLOCK parameter’s value is the R-BUS jack to
which the ADA-7000 is connected, the ADA-7000’s CLOCK SOURCE should be set
to INTERNAL or WORD CLOCK.
• When the VS-2480 MASTER CLOCK is set to INT, COAXIAL IN, OPTICAL IN,
WORD CLOCK or EXT TIME CODE, the ADA-7000’s CLOCK SOURCE should be
set to R-BUS. However, if a separate word clock generator is supplying word clock
directly to the ADA-7000, set the ADA-7000’s CLOCK SOURCE to WORD CLOCK.
The following table explains the CLOCK SOURCE values and tells you how to set the
VS-2480’s MASTER CLOCK parameter with each ADA-7000 CLOCK SOURCE value.

SAMPLING FREQ

SAMPLING FREQ provides a readout of the sample rate at which the ADA-7000 is
operating and capturing audio through its input jacks. When the ADA-7000’s CLOCK
SOURCE parameter is set to INTERNAL, SAMPLING FREQ automatically switches to
the current project’s sample rate, unless the project uses the 88.2k or 64k sample
rates—the ADA-7000 doesn’t support the use of these two sample rates.

AE-7000 Settings

Turn down the volume for all connected equipment before changing the CLOCK
SOURCE value to avoid damage to your equipment.

If the ADA-7000
CLOCK SOURCE is:
This means that
the ADA-7000:
Set the VS-2480’s
MASTER CLOCK to:

INTERNAL uses its own master clock and sample
rate (see “SAMPLING FREQ” below).
the ADA-7000’s
R-BUS jack.
WORD CLOCK derives its clocking from the word
clock device connected to its rear-panel
WORD CLOCK jack.
the ADA-7000’s
R-BUS jack.
R-BUS derives master clock from the VS-2480. a clock source other
than the ADA-7000’s
R-BUS jack.
When the ADA-7000’s CLOCK SOURCE is set to any value other than INTERNAL, it
derives its sample rate from the selected master clock source.
