Overview

of

the

Digital

Audio

Tape

Deck

Serial

copy

management

system

This

unit

utilizes

the

serial

copy

management

system

that

permits

digital-to-digital

recording

for

one

generation.

You

can

record

CD

sound

or

other

digital

formats

through

a

digital-to-digital

connection.

(See

page

36.)

Three

sampling

frequencies

Recording/playback

can

be

done

with

three

sampling

frequencies

(48

kHz,

44.1

kHz and

32

kHz).

48

kHz:

For

analog

and

digital

input

signals

in

a

standard

mode.

44.1

kHz:

For

compact

disc

and

pre-recorded

DAT

tape.

32

kHz:

For

analog

input

signals

in

a

long-play

mode.

Long

play

mode

This

unit

can

operate

in

a

long-play

mode.

Analog

input

signals

can

be

recorded

or

playback

for

up

to

four

consecutive

hours

when

the

DT-120

DAT

cassette

tape

is

used.

The

sampling

frequency

will

be

32

kHz

in

the

long

play

mode.

Visible

cassette

loading

You

can

view

the

tape

operation

through

the

lid

of

the

cassette

compartment.

Due

to

a

revolutionary

new

transport

mechanism,

cassette

loading

time

has

been

significantly

reduced.

Excellent

sound

quality

¢

1-bit

A/D

converter

For

the

A/D

converter

section

which

converts

analog

input

signals

to

digital

signals,

the

unit

employs

a

1-

bit

A/D

converter

which

theoretically

generates

no

zero-cross

distortion

for

a

clear,

elegant

sound

quality.

Pulse

D/A

converter

Superior

playback

performance

is

achieved

with

a

1-

bit

D/A

converter.

Rich

variety

of

subcode

information

This

unit

can

record

subcode

information

such

as

Start

IDs,

program

numbers,

Skip

IDs,

and

absolute

time

data,

enabling

you

to

quickly

locate

tunes

and

display

the

playback

time

in

the

same

manner

as

when

playing

compact

discs.

Post

edit

recording

of

sub

codes

You

can

record

or

rewrite

the

following

sub

codes

after

the

audio

signal

recording

has

been

completed.

Start

ID:

Signifies

the

beginning

of

a

selection.

Program

number:

Gives

a

number

to

the

selection.

Skip

ID:

Signifies

the

beginning

of

a

portion

to

be

skipped.

End

ID:

Signifies

the

end

position

of

recording/

playback.

Since

sub

codes

are

written

on

the

tape

separately

from

audio

signals,

the

audio

signals

are

not

affected.
