INSTALLATION

The recorder may be installed on any stable sur-
face that is not subjected to vibration or intense mag-
netic fields. It should not be placed directly on a loud-
speaker, a television set, or a large power amplifier
where it might pick up hum from the amplifier's power
transformer. if you wish to install the recorder next to
an amplifier on the same shelf, place the recorder on
the left so that its cassette compartment will be locat-
ed away from the amplifier.

WARNING TO UK USERS. If this appartus is not fit-
ted with a UK three-pin plug, do not attempt to insert
the attached plug into a UK mains socket. Instead, cut
the plug from the mains lead and attach a fused UK
three-pin plug using the following safety advice on
wiring.

IMPORTANT. The wires in this mains lead are
coloured BLUE and BROWN;

BLUE: NEUTRAL BROWN: LIVE

The colours of these mains lead wires may not corre-
spond with the coloured markings identifying the ter»
minals in your plug. In this case the BROWN wire
must be connected to the terminal which is marked
L(ive) or coloured RED. The BLUE wire must be con-
nected to the terminal marked N(eutral) or coloured
BLACK. No connection should be made to the termi-
nal marked E or coloured green or green and yellow

PRECAUTIONS

To ensure that maximum performance of the NAD
613 cassette deck is maintained over time, please
bear the following precautions in mind:

THE DECK

A. Make sure the heads and transport are cleaned
regularly. Please referto page 8.

B. Demagnetise both heads and tape guidance from
time to time. Please refer to page 8.

C. The bearings and other moving parts have been
treated with special lubricants and are therefore main-
tenance-free. Additional lubrication can actually cause
malfunctioning.

D. Do not position the deck near equipment with
strong magnetic fields, such as loudspeakers or tele-
visions, etc.

E. Place the deck on a solid, flat surface.

F. Avoid dirt, dust, sand, etc. from entering the deck.
G. Avoid placing near transmitters: they can generate
high frequencies which may cause malfunctioning of
the deck.

H. Ensure the cassette deck compartment lid is
closed when the deck is not in use. Open it only for
taking a cassette in or out, or for cleaning the heads
and tape guides.

|. Do not place the deck directly on top of a (power)
amplifier or receiver. The deck may pick up hum from
the amplifier's power transformer. Some amplifiers
can also generate a fair amount of heat, even when
on stand-by.

WARNING : BEFORE PLUGGING IN THE UNIT FOR
THE FIRST TIME, READ THE FOLLOWING SECTION
CAREFULLY.

Some models are designed for use only with the
power supply voltage of the region where they are
sold.

NAD 613 CASSETTE DECK

European models:
U.S.A. and Canadian models:

AC 230V, 50HZ
AC 120V, GOHZ

THE CASSETTE TAPES

A. Store the cassette tapes in their jewel case, away
from dust. Never store tapes in direct sunlight or very
hot places.

B. Always use cassette tapes of a good quality.
Besides mediocre results, poor quality tapes can
cause excessive head wear.

C. Never touch the exposed tape itself or take it out of
its cassette casing.

D. In most cases the cassette tape has a five to eight
second leader tape at both the beginning and end of
a cassette tape. As you cannot record on this leader
tape, be sure to commence recording beyond this
tape.

REAR PANEL CONNECTIONS &
CONTROLS.

The numbers in the text refer to the connections in
figure REAR PANEL CONNECTIONS

This cassette deck can be connected to almost all
pre-amplifiers, integrated amplifiers or receivers.
Ensure the plugs are fully inserted and the recording
and playback cables are connected properly.

1. INPUT.

Connect a cable from the decks LINE IN" jacks at
the rear panel to the TAPE OUT or REC jacks of your
amplifier. Connect the left channel of the deck to the
left channel of the amplifier and connect the right
channel of the deck to the right channel of the amplifi-
er. Normally, the red plug is used for the right chan-
nel, the black or white plug for the left channel.
Please refer to figure 1.

2. OUTPUT.

Connect a cable from the deck's LINE OUT jacks
at the rear panel to the TAPE lN, PLAY, or MONITOR
jacks of your amplifier. Connect the left channel of the
deck to the left channel of the amplifier and connect
the right channel of the deck to the right channel of
the amplifier. Normally, the red plug is used for the
right channel, the black or white plug for the left chan-
nel. Please refer to figure 1.

3. NAD LINK.

The NAD Link IN" connector allows the NAD 613
to be operated by external remote control signals
passed from another NAD remote control component
featuring NAD Link, e.g. AV 716 receiver. NAD Link
works in a daisy chain fashion, connections going
from one unit to the next one. Many NAD receivers
and AV components come supplied as standard with
an NAD system remote control which sports buttons
for most used tape transport functions (Play, Record,
Fast Forward, Rewind, Stop, etc.). It is recommened
that the NAD 613 is the second unit in the daisy chain
after the master unit, usually a receiver. Connect a
cable from the master unit Link Out (e.g. the AV 716)
to the NAD Link IN jack on the 613.

level will result in excessive tape hiss. whereas too
high a recording level will result in distortion. The
standard procedure is to set the recording level to
accommodate the loudest part of the music, and then
leave the controls alone. Set the control so that sus-
tained sounds, e.g. a singing voice or full orchestral
chord reaches the red segments (up to 4 dB). With
music that spans a wide range of volume levels, this
may mean that the quiet portions of the music will be
recorded at a level of -20 dB or less (with no seg-
ments illuminated). This is normal.

The BALANCE (13) control will allow you to alter
the left/right balance of a recording. When turned fully
counter clock-wise, only the left channel will be
recorded. whereas turned fully clock-wise only the
right channel will be recorded. For normal use the
control is set in the detent in the centre of its range.
recording each channel with equal levels.

If you wish to erase a tape, without making a new
recording. follow the procedure as described above,
but turn the RECORD LEVEL (12) control fully
counter clock-wise. No recording level segments will
illuminate.

ACCIDENTAL ERASURE PREVENTION.

Whilst making a new recording any previous
recordings already on the tape will automatically be
erased. If you wish to protect a tape from being
erased or re-recorded accidentally, you can remove
the tapes protection tabs. This way the record func-
tion will not engage. Please note that most pre-
recorded tapes commercially available already have
the tabs removed. Using adhesive tape over the
holes will enable the circuits to record again.

CrO2 (type II) and Metal (type IV) tapes have addi-
tional holes in the cassette housing, enabling the
deck to recognize" the various tape types. Make sure
you do not cover these holes as well! Refer to figure
3.

THE PLAY TRIM CONTROL.
Position the PLAY TRIM control in the 0" (centre
detent) position for normal play-back.

Errors in high frequency response often occur in
cassette recordings. especially in tapes that were
recorded on one machine and are being played on
another. These errors arise from tape saturation -
particularly those tapes recorded on decks without
HX Pro headroom extension -, from biasing that didn't
match the tape when the recording was made, and
from differences in equalisation and head azimuth
among recorders.

These errors cause mis-tracking of the Dolby NR
circuits. which in turn cause the faults to be magni-
fied by the circuits, often resulting in dull sound.

Play Trim is a special high-frequency play-back
equalisation circuit. used to restore accurate play-
back response before Dolby NR decoding takes
place. Standard play-back equalisation. for correctly
recorded tapes, is provided when the Play Trim con-
trol is set at the detent in the centre of its range.

When playing tapes, set the DOLBY NR selector to

match the recorded tape. If the recording sounds dull,
turn the Play-Trim up (clock-wise) to restore accurate
highs. if the recording sounds edgy or sibilant. turn
the Play-Trim down to obtain smoother treble.

NOTE: The Play Trim control only affects play-back
and doesn't function whilst making a recording.

MAINTENANCE

The bearings and other moving parts have been
factory treated with special lubricants and do not
need any special attention.

Dirt, dust and tape-oxide can potentially damage
the heads and tape guidance. besides degrading the
sound quality both on play-back and recording. Parts
in direct contact with the tape therefore need to be
cleaned regularly.

NOTE: Make sure the receiver or amplifier is
switched off before cleaning or demagnetising the
heads.

CLEANING

Open the cassette compartment door. At the bot»
tom of the compartment you can see the heads and
tape guidance (capstan and pinch-roller). Refer to
figure 4.

Clean the heads (A & B) and the capstan (C) using
cotton wool buds with pure alcohol or with a dedicat-
ed Tape Recorder Cleaner.

Clean the pinch-roller (D) using only distilled water.
Never use alcohol on the roller, as the rubber will dry
out. Alternatively. you can use a special cleaning cas-
sette. Be sure to use a cassette that cleans all parts
illustrated in figure 3.

DEMAGNETIZING

Parts in direct contact with the tape will become
slightly magnetic over time, This magnetism will
increase hiss. both during play-back and recording.

It is therefore advisable to demagnetise the heads.
pinch roller and other metal tape guidance parts from
time to time. using a demagnetiser or a demagnetis-
ing cassette. Follow the instructions of the demagne-
tiser or demagnetising cassette.

WARNING
Keep demagnetisers away from your tapes, they
can accidentally erase the recordings.

Your dealer will be able to advise you and supply
the proper accessories for both cleaning and demag-
netising.
