OPERATION

EXPLANATION

I.

Regarding

recording

frequency

characteristic

and

bias

Ordinarily,

if

the

recording

bias

current

is

increased,

REC/PB

frequency

response

level

in

the

high

frequency

region

(about

1OKHz

and

above)

drops,

and

if

the

bias

is

decreased,

the

response

rises.

Regarding

the

basic

operation

of

HX

PRO

(Refer

to

Fig.

1)

The

HX

PRO

uses

the

«%

PCI297CA

IC.

The

operation

is

in

accordance

with

the

following.

1)

At

(a),

the

recording

bias

is

added

onto

the

audio

signal,

and

the

recording

signal

is

detected.

This

is

the

same

as

the

recording

head

recording

the

signal

on

the

tape.

2)

The

signal

of

1)

preserves

the

frequency

response

with

the

integrated

circuit

of

(b).

By

means

of

the

frequency

of

Fig.

1,

the

frequency

which

is

effective

from

the

beginning

is

determined.

In

the

ordinary

situation,

this

is

half

the

audio

band

(1OKHz),

(lLOKHz

~

7.5KHz).

|

3)

At

(c),

in

order

to

use

the

affected

waveform

after-ward,

absolute

detection

is

carried

out.

Frequency

=

(2.1)

4)

At

(d),

the

waveform

peak

value

is

detected.

The

output

becomes

the

peak

DC

voltage.

5)

At

(e),

the

standard

voltage

and

the

voltage

of

(4)

are

compared.

6)

With

the

output

of

(e),

the

frequency

generation

level

is

controlled

(voltage

controlled

amplifier).

That

is,

the

bias

size

iS

varied.

7)

Summing

up

|)

~

6):

At

(a),

the

time

constant

(frequency)

that

is

detected

in

the

recording

signal

is

preserved,

and

above

a

certain

frequency

and

above

a

certain

level,

the

VCA

controls

the

bias

current

by

causeing

its

reduction.

When

this

is

done,

in

the

maner

shown

in

the

explanation

of

Item

I

above,

the

frequency

high

region

is

raised.

With

this

control,

the

audio

signal

is

instantaneously

dealt

with.

3.

Regarding

the

operating

conditions

of

the

HX

PRO

1)

With

equation

(2.

1)

noted

above,

the

effect

begins

at

the

frequency

thus

determined.

Above

a

certain

level

the

effect

begins.

(Substantially

0

dB:

In

the

vicinity

of

500mV

line

out)

The

audio

signal

component

level

is

dependent

upon

the

waveform

after

point

(c).

REPEAT

(FULL

or

and

AMCS.

The

FULL

REPEAT

function

enables

five

plays

of

one

full

side

of

the

tape

currently

on

the

machine.

It

operates

such

that

when

FULL

REPEAT

has

been

selected

and

the

end

of

the

tape

is

sensed

during

PLAY

or

rewind

then

the

machine

will

automatically

enter

this

mode.

Where

the

end

of

the

tape

is

sensed

and

this

mode

entered

during

play,

then

the

latest

completed

play

will

be

deemed

to

be

the

first

play

and

the

tape

will

then

be

played

four

more

times.

The

use

of

the

PAUSE

or

its

release

during

the

course

of

a

FULL

REPEAT

will

not

have

any

effect

on

the

subsequent

number

of

repeats.

(see

Fig.

2)

The

BLOCK

REPEAT

function

enables

five

consecutive

plays

of

the

section

between

any

two

selected

points.

The

start-

ing

point

is

the

point

at

which

the

BLOCK

REPEAT

function

is

switched

ON,

or

alternatively,

if

the

BLOCK

REPEAT

function

is

already

switched

ON,

it

is

the

point

during

play

at

which

the

PLAY

button

is

depressed.

If

the

PLAY

button

is

depressed

more

than

once

then

the

effective

starting

point

will

be

the

last

point

at

which

the

button

was

depressed

and

in

the

case

of

a

reverse

deck,

if

the

end

of

the

tape

is

sensed

before

the

return

point

has

been

set

then

the

mechanism

is

reversed

and

that

point

becomes

the

new

play

starting

point.

The

return

point

is

the

point

during

F-PLAY

at

which

the

REW

button

is

depressed

or

the

point

during

R-PLAY

at

which

the

FF

button

is

depressed.

However,

in

the

case

of

a

one-way

deck,

if

the

end

of

the

tape

is

sensed

before

the

return

point

has

been

set

then

the

end

of

the

tape

itself

will

become

that

return

point.

The

use

of

the

PAUSE

or

its

release

during

the

course

of

a

BLOCK

REPEAT

will

not

affect

the

continuation

of

the

operation

but

if

any

other

function

is

activated

during

the

course

of

a

BLOCK

REPEAT

then

this

will

cause

the

BLOCK

REPEAT

function

itself

to

be

terminated

at

that

point

and

then

new

operation

to

begin.

When

the

return

point

is

sensed

for

the

fifth

time

then

the

BLOCK

REPEAT

operation

is

terminated

and

the

machine

stops.

(see

Fig.

3)

*

Where

the

full

BLOCK

REPEAT

section

is

set

to

cover

too

short

a

period

the

return

point

should

be

moved

out

until

sufficient

length

has

been

allowed.
