Changing the clock
If the desired clock source
has a frequency selection option, select the
frequency.
The stereo digital inputs (
D-IN1
and
D-IN2
) can have
their sampling frequency manually set here (but
remember that if the frequency converter is turned
on, they cannot act as clock sources). To enable the
manual setup for both digital inputs, which copes
with ambiguous embedded C bit (channel status bit)
information, check the checkbox, and select the sam-
pling frequency. Note also that if the optional AES/
EBU slot card is fitted, the settings made here are
applied to this card as well.
The following options relate to the different clock
sources available:
When you have selected the appropriate option for
the clock source, move the cursor to the checkbox
and press
ENTER
.
A checkmark (
) appears in the box if a valid clock
signal is present, a cross (
) if it is not present, and a
question mark (
?
) if the clock signal is out of range.
An appropriate popup message is shown in the event
of an error in the selected clock signal.
If the clock signal is a valid one, and one which can
be used, an appropriate popup message (depending
on the action selected when the clock is changed
(“Clock change action” on page 56) is shown).
Press
ENTER
to change the clock, or a cursor key to
cancel the action.
Clock phase
The phase of the clock signal
received at the
WORD SYNC IN
or transmitted or
passed through the
WORD SYNC OUT/THRU
termi-
nal (see also “WORD SYNC (IN and OUT/THRU)”
on page 55) can be inverted using the on-screen
phase controls.
OUT SPEED
Note that in high-speed mode, the
clock transmitted from the
WORD SYNC OUT
can be
either the high-speed (88.2/96) clock or the corre-
sponding normal speed (44.1/48) clock.
