D-CLOCK WORD CLOCK MEASUREMENT
AND DISTRIBUTION AMPLIFIER
The D-Clock is a dual input/twenty output word clock distributor with a 16
character blue LCD display providing a reference measurement of the
incoming sample rate. Both AES/EBU and BNC word clock inputs feature a
zero latency loopthrough output with switchable high impedance to maintain
the correct level of the digital signal for onward distribution. The D-Clock dis-
plays incoming sample frequencies up to 768 kHz to an accuracy of 2ppm
(parts per million) with two further modes - sample frequency with ±ppm error
and sample frequency with % pull up/down for video users.
Sixteen BNC clock outputs are situated on the rear panel with a further four
BNC clock outputs on the front panel for quick patching to other digital
devices. The word clock outputs can be derived from either a word clock
input or alternatively an AES/EBU audio signal from which clock information
can be stripped. In the latter case, one of the many mic pre’s with internal
A/D conversion but no word clock output can be utilised as the master clock
source for the whole digital studio.
