These
two
types
of

allow
the

to
be
used
with

types
of
VTRs:

“BETACAM”
and

and
even

—
When
a
VTR
is
connected
through
the
9-pin
remote
contro!
connector,
you
can
select
a
CTL
signal,
time
code
or
RTC
(relative
time
code)
for
editing.
When
RTC
is
selected,
the
time
code
is
used
as
an
edit
reference
and
its
progress
is
counted
as
CTL
on
the
time
counter.
RTC
can
be
used
to
determine
how
far
the
desired
tape
point
is
from
the
IN
point
as
it
can
be
reset
in
the
same
manner
as
a
CTL.
ime
learning
capability
The
unit
can
detect
the
pinch
on
delay
time
of
the
connected
VTR
and
hold
this
data
for
a
week
even
after
the
power
is
turned
off.
Therefore,
the
operation
with
the
connected
VTRs
is
very
smooth
and
no
discontinuity
of
the
picture
is
produced
by
this
unit.
You
can
connect
not
only
the
VTRs
which
have
the
same
remote
connectors
but
also
VTRs
having
a
9-pin
remote
connector
and
those
having
a
33-pin
remote
connector
to
the
unit,
and
control
them
remotely.
In
the
assemble
mode,
the
video
signal
and
audio
signals
(A1
and
A2)
are
edited
together
at
the
same
time.
In
the
insert
edit
mode,
they
can
be
edited
separately.
The
unit
can
also
perform
the
split
edit.
Therefore,
you
can
set
the
audio
IN
point
independently
from
that
of
the
video
channel
and
vice
versa.
Materials
you
are
to
edit
can
be
previewed
and
those
that
you
have
edited
already
can
be
reviewed.

The
BVW-10
is
a

and

‘Synchronize
The

connector
allows
the
unit
to
synchronize
with
the
connected
VTR.
Therefore,
the
unit
can
perform
absolutely
precise
editing.
When
the
VTR

has
the

function
is

to
