PAUSE/MUTE KEY

This is an original

feature

developed by DENON. lt enables

bottr

pause

functioning

during

playback

as well as

pause

and mute

functioning

during

recording

operations. lt is especially

convenient

for

adding

non-recorded

intervals

(blank

spaces) between

selections being recorded.

l. By

continuously

pressing

the PAUSE/MUTE

key

during recording,

non-recorded interval

(blank

space)

will

be

recorded on the tape.

When the PAUSE/MUTE

key

is released during recording, the

deck reverts to the record-

ing

standby

mode.

To

restart

recording

(or

DOLBY HX.PRO

HEADROOM EXTENSION SYSTEM

This deck

is equipped

with the

DOLBY

HX-PRO headroom extension system. Since the system

functions

automatically

during recording, no switching operation or

adjustment

is required.

The system

is effective

with any type of Normal,

CrOz

or

Metal

tapes.

The Dolby HX-PRO headroom

extension

system

functions during

recording to lift up the

saturation

level in the

treble range. Therefore, most of the treble range components

distorted

or lost during recording

on conventional cassette decks

are

more faithfully recorded on the

new

DR-M33HX/M44HX cassette deck.

Features of the DOLBY

HX-PRO headroom

extension system

(

1) Performance

of Normal and

CrO,

tapes can

be

up-graded

closer to that

of Metal tapes.

(2)

The dynamic

range in the treble is. improved signif icantly.

(3)

Since no

decoding in

playback

is

necessary, the improvement

can be obviously

heard on

any

hi-fi

playback

system

including

portable

components and

car systems.

(4)

The

system

functions whether the

Dolby

B/C NR

is

engaged

or

not.

DOLBY C

NOISE

REDUCTION SYSTEM

r

The Dolby

noise

reduction

system substantially reduces

the tape

background

noise

(hiss)

in'

herent in the cassette

medium. Dolby B NR is most

widely in use.

However,

Dolby

C

NR is

a much

more recent

development

and represents a

signif icantly

improvement

over Dolby B NR.

rTape

background noise consists

primarily

of

high

freqnency information

which

is

particularly

annoying during

soft

passages.

The Dolby NR

system

increases the

level of low volume mid

and high

frequency

signals during

recording and

reduces

the level

of

these signals

by

an

identical

amount

during

playback.

As a

result, the

playback

signal is identical to the original source

signal, but the level

of background

noise

generated

by

the tape is

greatly

reduced.

r

The operating

principle

of Dolby

C

NR is

similar

to that

of B except for

the encoding/decoding

response curves. The

noise reduction effect obtained

by

Dolby C

NR is up to

2OdB,

compared to

lOdB with Dolby B NR. ln addition,

Dolby

C NR uses

an antisaturation network and spectral

skewing

circuitry,

and significantly

improves

the dynamic

range

in the mid to

high

frequencies.
