CONTROL DESCRIPTION
DISPLAY A Blue/White LCD display wth three switchable modes of operation: FREQ, ±PPM and ±%.
The mode that is displayed during power down is saved for the next session.
The display accuracy is 2ppm at all sample rates up to 768kHz, or 0.1Hz increments @
48KHz sample rate
MODE A switch controls the mode of display enabling you to read the incoming sample rate in your
preferred manner. Pressing the switch toggles through the three modes of FREQ, ±PPM and
±%, with led indication.
FREQ
Displays the actual frequency to four decimal
places upto >768kHz.
±PPM
Displays the nominal sample rate with +/- ppm
(part per million) error indication for 32, 44.1, 48,
96 & 192KHz
±%
Displays the nominal sample rate with percentage
pull up/down indication for 32, 44.1, 48, 96 &
192KHz
INPUT SOURCE CLOCK PRESENT
Sets the input source
to be used - either AES
or BNC as connected
on the rear panel - with
led indication.
The two LED’s indicate the status of the input
sources. When a led is lit continously a strong
signal is being recieved by that input source and
the D-Clock is “locked on”. If a led flickers, the
signal for that particular input source is weak or
unstable - in this case the source of this weak
signal should be located and improved.
