To ensure this, one device in the setup
must be set as the master clock. The
other devices will then use the master
clocks signal to stay in sync. There can
only ever be one master clock present in
a chain.
The master clock signal can be sent
either via an Optical cable embedded
into the digital signal data, or through
a BNC clock line cable. Please bear in
mind that the clock will only travel in one
direction through these conenctions,
from a devices output to a devices input.
Choosing a Master Clock
In a digital setup, there can be a number
of options when determinging which
device should be your master clock.
Quite often the best device to set as the
master is the one that is connected to
the computer (where possible) such
as an audio interface. This way, when
you open a project in a DAW, the audio
interface should change to match the
project sample rate, and therefore
change the sample rate of all the slave
devices. However this depends on the
devices being used.
iD44 as the Master Clock
With the iD44 set as the Master Clock
the other devices in the chain can be
clocked by either the Optical Port or the
BNC word clock output. When clocking
just one device, clocking via the optical
port would be the simpliest option,
simply connect the TOSlink cable up to
the iD44’s optical output and to the other
digital devices input.
Then set the other device to Slave o the
iD44’s clock.
If you are using multiple devices then it
is reccomended to use the BNC word
clock output and then use T-connectors
to Daisy Chain the Devices together.
It is important to note that the final
device in the chain should have its BNC
connector terminated with 75 Ohms to
stop reflections of the clock signal. This
should be an switchable option on most
devices.
