CONTROL DESCRIPTION
DISPLAY
A Blue/White LCD display with 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
The LED’s
indicate the
status of the
input sources
for both Sync1
& Sync2 in
word clock &
A E S - 3 i d .
When a led is lit continuously a strong signal
is being received by that input source and
the D-Clock-R 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.
CLOCK PRESENT
The two LED’s
indicate the input
source being
used - either
Sync1 or Sync2.
By default Sync1
would be used,
however, should
this signal be weak or missing
the D-Clock-R will automatically
switch to using Sync2 as the
clock input.
ACTIVE INPUT
The two LED’s
indicate the
power supply
being used -
either PSU1 or
PSU2. With both
LED’s lit the
power is shared
between the two PSU’s. A LED
unlit identifies that the PSU is not
in use and the source of this
problem should be found as soon
as it is convenient. The DMS-6
can operate via both or either of
the PSU’s.
