® "Dolby C-Type Noise Reduction System
In addition to the standard Dolby B-type NR system,
your deck provides the ultimate in noise reduction
systems, Dolby C. Even with normal cassette tapes, the
trailing off of the high frequency respor.ee is dramati¬
cally improved, and with metal tapes recorded at the full
0 dB level, the frequency is flat up to 15 ~ 20 kHz.
® HX-PRO System
Since HX-Professional system keeps Active Bias con¬
stant, it allows natural-sounding recordings of the iow
frequency range. When you record high level, high fre
quency sound in a conventional way, frequency charac¬
teristic will be reduced due to self-demagnetization. HX-
PRO works so as to reduce this self-demagnetization far
better, so that higher level recording may be capable.
Therefore, HX-PRO gives normal tape almost equal per¬
formance of metal tape.
® Electric Auto-Search Function
This makes it easy to find the head portion of each item
in the music tape.
® Metai-Tape Compatible
Tape selector switch for METAL position is added to
assure the best performance of metal tape. Since the
tape selector switches are provided for 3IAS and
EQUALIZATION independently; METAL, CrOa, FeCr,
LN, the best performances of each tape can be assured.
® 3-Head, 2-Motor Mechanism
A 3-head configuration is used to allow monitoring of
the recording while it is inprogress. Twoseperate motors
are used — one for the capstan and one for the two reel
drives — in a mechanism that boasts extremely high
precision and highly reliable tape transport for low wow
and flutter.
® Feather-Touch Operational Controls
Semiconductor logic control gives pleasant, feather-
touch control of the mechanism. Direct changes are
possible between, for instance, play back and fast for¬
ward or rewind. Again, a remote control can be availa¬
ble.
a Memory Auto-Repeat Function
When playing back the same item repeatedly, or the item
just recorded from its beginning, the tape can be re¬
wound to the desired position readily.
a Electrical Tape Counter
An electrical digital display is used for the tape counter.
It is both easier to see and more accurate counter of start
and stop position because of its faithful to tape progress,
compared with analog type.

Always use at 120V AC
This unit isdesigned for use
at 120V AC. Do not con¬
nect the unit to an outlet
supplying a higher voltage
to prevent fire.
Handle the AC cord carefuSiy
® Always hold the plug when disconnecting the AC cord
from the outlet. Pulling at the cord may cause dis¬
continuity.
® If the unit is not used
for a prolonged period,
disconnect the plug
from the outlet.
© Do not place or drop a
heavy material such as
furniture on the cord.
Otherwise, the cord may
be damaged to cause
fire or shock hazard.
Do not open the cabinet
To prevent shock hazard or unexpected trouble, do not
tamper with internal components for inspection or main¬
tenance. Harman Kardon does not guarantee performance
degradation resulting from any modification.
When water ora metal piece enters the unit
When water, a hairpin or wire accidentally enters the unit,
immediately extract the AC plug from the outlet to prevent
shock or trouble.
Locations for Installation
Place this unit on a firm flat base.
Avoid the following locations:
® Place exposed to direct sunlight or near a heat source
® Place exposed to excessive moisture
® Cold place such as near a cooling air outlet
® Dusty place
® Place exposed to excessive vibration
® Poorly ventilated place
® Place near a TV receiver, speaker or other object that
generates strong magnetism
When piling with other components, carefully plan so as
not to obstruct heat radiation from a pre-mainamplifier or
mainamplifier. Use of a Harman Kardon audio rack is re¬
commended.
*Always disconnect the plug from the outlet before
making connections with other components.

® Be sure to remove the cassette tape from the cassette
compartment after the end of operation to keep the tape
quality and maintain the deck performance for a long
time.
® Store cassette tapes off from a strong magnetic field
such as near a TV set, amplifier and speakers to prevent
adverse effect on the recorded sound.
® Before a cassette tape is played back or recorded, be sure
to eliminate tape slackness. A slackened tape, if used,
may cause jamming in the tape running mechanism.
Remove tape slackness
by winding with a pencil.
® If the sound recorded on the tape is desired to be pro¬
tected from accidental erasure, remove the erase-preven¬
tion tabs. With these tabs broken out, accidental erasure
can be prevented even if the RECORD button is inadvert¬
ently pressed.
® If it is later desired to record on a cassette tape protected
in this way, cover the holes with adhesive tape.
Your deck provides the Dolby C-Type Noise Reduction
system, which is said to be the ultimate in noise reduction
system. Also, you can work the standard Dolby 8-Type
Noise Reduction System by changing the B-C select switch.
The Dolby NR System is one of the methods for reducing
the noise that is created during the play back of a tape, and
is now widely and internationally used. The noise which
this system reduces largely emits from the tape itself and
this system cannot reduce the noise which comes from the
program which is being recorded. Therefore, in order for
the Dolby NR System to function more effectively, it is
important to avoid recording from signals either from re¬
cords or FM radio that contain a lot of noise, i.e., it is
important to choose signals with as little noise as possible.
Principle
Any magnetic tape used on a tape recorder contains native
noise. In particular, among these noises, the middle and
high frequency noises, which we can easily pick up by
hearing, are called "hiss noises", and they are said to be
caused by the site of magnetic particles on the tape. Hiss
noises decrease if the magnetic particles are small, and also
decreases if the tape is played at a higher speed. In other
words, the high speed of the tape playing, and the small
size of the magnetic particles produce the same effect
as regards the hiss noise. In this respect a cassette tape
played at a low speed, will produce more hiss noise.
Function of the Dolby Noise Reduction
When the recording input signals are lower than the stan¬
dard level, those middle and high frequency sounds among
those signals are gradually strengthened and recorded. The
signals will return to the original state if a tape is played
back opposite to the way it was recorded, i.e., if it is played
back with middle and high frequency sounds above the
standard level being gradually weakened. At the same time
tape hiss sounds, which are middle and high frequency
noises, created during the play back are reduced accord¬
ingly, as the signals become smaller. Noise reduction is
achieved in this way.
While the Doiby B-Type NR System has only the noise re¬
duction capacity of the noise ievel of 10 dB, the Dolby C-
Type NR System has a capacity of 20 dB. This C-Type NR
System, in comparison, has an improvement in its function
in the high frequency range so that it can be used for 0 dB
recording. The Doiby C-Type NR System assures enough
dynamic range and SN ratio to record a Hi-Fi program
source.
