The
points to
be
borne in mind when recording
from the various
sources are
detailed in the
following
sections.
Copying
from
Records
There are
two
ways
in which the turntable can be connected
to
the
unit:
'1.
Connect
both the turntable and
cassette
deck
to
a stereo
amplif
ier or receiver and
switch the program selector switch
of the
receiver
(amplifier) to
PHONO.
2. To
connect the
turntable directly
to
the
cassette
deck pro-
ceed as
follows:
Turntables whose
cartridge leads have
cinch
plugs are con-
nected
to the LINE lN
jacks (black
=
right
channel
,
white = left
channel).
Turntables whose
cartridge leads have
DIN plugs are connected
to the
REC/PB
jack. For
a player
with a piezo-electric
(ceramic
or crystal) cartridge
this
is
all
that
is
required. For aturntable
with
a
magnetic
or dynamic
cartridgethe
Dual
TVV
47
head
amplifier is required. ln
this
case,
yöu
will
also need
the
Dual adapter, (part
No. 2624831
if your turntable
has
cinch cartridges
leads.
Recording
Radio
Broadcasts
lf
the
cassette
deck and a
tuner/receiver are connected
to
a
HiFi
amplif ier,
you
can record audio
programs
without changing
the
cable
connections.
lf
you
should wish
to
connect a
tuner or radio
directly to
the
cassette
deck,
this can
be
done
by way of
the LINE lN
jacks in
the
case
of
audio
cables
with
cinch
plugs (black
=
right channel
,
white
=
left
channel) and
by way
of
the
jack
REC/PB in
the
case
of audio
cables
with DIN
plugs.
Recording
from Another
Recorder
lf
you
wish
to
record on
your
cassette
deck
from another tape
iecorder
or
cassette recorder,
you
can
do this
with the
audio
cable included
with
the cassette deck. Connect
the unit
from
which
the
recording
is
being made
to the
REC/PB
jack. lf,
however,
you wish
to
make
a
recording
from your
cassette
14
deck
to
another tape deck
or
cassette
deck,
it
may be
neces-
sary
to
connect
the
dubbing
lead (Dual
part number 2268181
to
the connecting
jack
of
the recording deck.
When
making connections via the
cinch
jacks, always connect
the audio
cable
to the LINE lN
jacks
of
the recording
unit
and
to the LINE OUT
jacks
of
the
unit
from which the recording
is
being
made.
Microphone Recordings
The HiFi
stereo cassette deck is
fitted
with
a
jack
for low
and
medium impedance microphones
with
values between
200
and
1000 Ohms and
a
6.35 mm
d
(1
14
inch) coaxial plug.
For
this we
recommend
the
Hi
Fi Electret capacitor microphones
Dual MC
304 and Dual
MC 316.
For stereo recordings,
a
single stereo microphone or
two
mono
microphones
of
the
same
type should
be
used. For mono
micro-
phone recordings only the
track
is recorded
to which
the micro-
phone has
been connected.
ln this
case,
it
is
recommended
that the
unused level
control
be
turned
back
to "0". AlI
other
channel inputs are automatically deactivated when
a
micro-
phone
is
connected.
Erasing
The
cassette
deck
erases
all
previous recording when a new
recordlng
is
made.
lf
you
want
to
erase
a recording
without
making a
new one, play the
cassette
through
with the controls
set
for
"recording"
but
with
all controls
set
to "0".
All
compact
cassettes
have
two
slots
on
thei
r
rear edge
which
are
partially
covered
by plastic
tabs.
You can
prevent accidental
erasure
of your
own recordings
by
breaking
out the appropriate
ta
bs.
Pre-recorded tapes bought
from
cassette dealers
are usually
al-
ready
protected
against accidental erasure
by
having
the
tabs
removed.
lf
you
wish
to
record
on
a
tape
protected in this way
it
is
only
necessary
to
close
the
slots temporarily by means
of
a
small
piece
of
adhesive tape.
Please
note that the additional slots present in
Cr02 tapes must
not
be
closed
by
adhesive
tape.
Technical
Data
Drive
The precision DC motor
is
fitted with
an integrated
frequency
generator and modern
control
lC for
speed
regulation.
A precision-
made
flat belt drives
the
capstan and
thereby plays
its
part in the
overall excellence
of
the
wow
and
flutter
charac-
teristics.
The tape take-up drive receives
its torque
via a second
belt direct
from the motor
so
that disturbances
such as
differen-
ces
in
cassette
winding
have
no effect on the tape
transport.
For
the fast wind
facility
a
functionally realiable gear drive
is
used.
This guarantees
trouble-free winding
even
for
older
cas-
settes.
An
electronic
circuit
continuously monitors tape
movement
and prevents formation
of
loops in the
tape.
At
the
same
time
it
also provides the
signals
for
auto
stop. This
function
is inde-
pendent of the
cassette
or tape switch
ing foi
I
.
Careful tape location and
precise
azimuth setting ensure
opti-
mum
treble reproduction
and prevent
level
f
luctuation.
Heads
The built-in
214-track lvl
+ X
sound head provides
excel
lent
magnetic
properties for
recording and playback
in conjunction
with
high resistance
to
wear.
Compact Cassette System
Your HiFi
stereo cassette deck
uses
a 214-track
format. Four
tracks are
provided
across
the
full width of
the tape
so
that two
stereo
tracks are available
in
each
direction
of play
and thus
the tape length
is used
for double stereo playing
time.
Cassettes
recorded
in
stereo
on your
cassette
deck can also
be
played on mono
cassette recorders.
That
is
to
say,stereo
casset-
tes are
fully
compatible
with
mono
cassettes.
Maintenance and
service
From time
to time it
is
desi
rable
to
clean
the
heads,
capstan,
pressure rollers and tape guides.
