CLK-C4 (clock converter):
Why use a clock converter:
When working in a studio or on a project where both Word-Clock
and Super-Clock equipment is being used it will be necessary to
synchronise the two standards. The CLK-C4 solves this problem
by its ability to automatically detect and lock onto whichever
standard clock is connected to its input and by having two 'pairs'
of outputs which can be selected to be either Word-Clock or
Super-Clock. The CLK-C4 has two LEDs on the front panel which
indicate whether the input is Word-Clock or Super-Clock and one
other LED which is only used with a Word-Clock input and
indicates whether Super-Clock is locked at the output.
(not used with a Super-Clock input)
Using the CLK-C4:
A cable with a characteristic impedance of 75 ohms must be
used, particularly with long distances and Super-Clock mode (any
video cable with BNC connectors). The CLK-C4, has a very high
input sensitivity and is able to receive a Word Clock and even
Super-Clock signal via a 100 metre cable and so can be used as
a buffer for long distances.
