Syncing
with
the
PCM-800
as
Slave
(With
the
DABK-801)
Once
the
same
time
code
has
been
recorded
on
both
the
master
and
slave
machines
you
can
synchronize
them.
Procedure for Synchronization
If
the
PCM-800
is
referenced
to
its
INT
(ernal)
clock
and
the
CHASE
MODE
DIP
switch
is
at
its
down/“Rechase”
position,
the
DABK-801
reads
the
master
and
slave
time
code
numbers,
compares
the
two,
and
issues
“speed-up”
or “slow-down”
commands
to
the
PCM-800
continually
in
order
to
keep
the
two
machines
in
sync
(“resolving”
or
“phase
lock’).
If
the
PCM-800
is
referenced
to
the
WORD
or
VIDEO
clock,
the
slave
drops
into
“clock
sync”
when
the
difference
between
the
master
and
slave
time
code
numbers
decreases
to
a
certain
degree.
Whatever the clock to which the PCM-800 is referenced, if the
CHASE MODE DIP switch is set to its up/“Free” mode position, the
PCM-800 goes into its normal play mode once synced up to the
master.
If you intend to perform a synchronized rehearse, do not press
REHEARSAL before CHASE. Once REHEARSAL is pressed,
CHASE cannot operate.
1 Make sure of the following :
* Your master machine is correctly connected to the PCM-800/
DABK-801 system.
* The PCM-800/DABK-801 system is referenced to the
appropriate clock.
If a VTR is the master and the CLOCK key is set to VIDEO, the
VIDEO IN connector of the DABK-801 must be fed with a
signal from which a clock can be derived regardless of VTR
transport status — a signal from sync generators, pattern
generators, etc. If for example, a video output signal is
connected instead, and the VTR stops playing, no clocks are
available; and, when play resumes, the system clock of PCM-
800 does not stabilize in time.
* The PCM-800 is ID-numbered “0.”
¢ The CHASE MODE DIP switch is set to the desired position.
* If you are in doubt about the type of time code in use on the tape
inserted to the PCM-800, verify it as per instructions in (4) of
page 2-3.
