These

two

allow

the

types

of

VTRs:

(relative

sélection

—

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

player,

and

other

VTRs

cannot

be

used

as

a

recorder

when

connected

to

this

unit.

You

can

easily

preset

various

data,

such

as

the

preroll

time

and

the

edit

timing,

needed

for

editing

on

the

‘Synchronize

The

REF.VIDEO

IN

connector

allows

the

unit

to

synchronize

with

the

connected

VTR.

Therefore,

the

unit

can

perform

absolutely

precise

editing.

When

the

VTR

which

has

the

dynamic

function

is

connected

to

this

unit
