OUTLINE

The

model

AG-7500

Editing

Video

Cassette

Recorder

has

been

developed

for

industrial

applications,

as

well

as

for

schools

and

studios.

By

the

use

of

the

S-VHS

system,

a

sharp

picture

with

high

resolution

is

obtained.

Advanced

editing

and

easy

operation

is

realized

by

the

introduction

of

high

reliability

mechanisms

including

the

two-reel

motor

drive

system,

DD

cylinder,

and

DD

capstan.

By

connecting

the

AG-A750

Editing

Controller

to

the

AG-7500,

you

can

fully

utilize

the

editing

functions

of

the

AG-7500

and

perform

more

accurate

editing

by

automatic

operation.

You

can

also

create

an

editing

system

by

connecting

the

unit

to

the

AG-A650,

NV-A500

or

NV-A960

Editing

Controller.

2.

Use

of

digital

YC

circuit

ePerfect

YC

separation

is

possible

even

in

noncorrelating

portions.

Because

of

burst

PLL

system,

non-standard

signals

can

be

separated,

too.

®As

digital

signals

are

process,

YC

can

be

separated

with

small

changes

by

a

stable

operation.

3.

Time

Editing

The

unit

allows

the

execution

of

time

code

editing

when

this

unit

is

connected

to

the

AG-A750

Editing

Controller.

Synchronization

is

also

possible

at

the

Edit

point

by

the

Capstan

Override

Connector.

itis

possible

to

at

the

linear

of

+1

frame

with

respect

to

the

video

timing.

(When

using

AG-A750.)

5.

Automatic

back

space

function

By

the

automatic

back

space

function,

video

and

audio

data

without

blank

portions

can

be

recorded

by

splicing.

6.

H-aligned

framing

servo

Sometimes,

when

editing

video

signals

conforming

to

the

CCIR

standard,

frame

phase

misalignment

or

horizontal

distortion

occurs

between

adjacent

edited

portions.

This

unit

employs

a

framing

servo

to

align

the

frames,

thus

eliminating

such

errors

at

the

edit

start

and

end

points.

7.

Flying

erase-based

editing

The

adoption

of

a

“rotary

erase

head”

makes

it

possible

to

achieve

top-grade

electronic

editing

without

noise

or

frame

mis-synchronization.

8.

Dual

audio

channel-Dolby*

NR

system

Because

there

are

two

normal

audio

tracks,

stereo

or

bilingual

programmes

can

be

recorded

and

played

back.

The

sound

quality

is

further

improved

due

to

the

built-in

Dolby
