Installation
if HiFi components in a rack or cabinet
(Compact-System)
are
to
function
properly,
i. e. without excessive accumulation of
heat and reciprocal effects, the following
must be strictly observed.
Depending
on
the
number
and
combination
of
the
employed
HiFi
components,
they
are
to
be
placed
one
above
the
other
into
the
rack
(Compact-System)
as
shown
in
the
pattern
below:
|
Record player (PS)
Receiver (R)
Cassette deck (CF)
This
is
the
maximum
number
of
com-
ponents
that
can
be
installed.
If
one
or
the
other
set
is
deleted,
leave
the
remaining
sets
in
the
sequence
indicated.
Same
is
valid
for
free
installation.
Mains
cables
must
not
be
placed
near
AF
leads,
like
connection
leads
of
record
player,
cassette
deck,
tuner
or
loudspeakers.
In
the
GRUNDIG
HiFi
range
you
will
find
the
appropriate
racks
and
Compact-
Systems
for
your
GRUNDIG
HiFi
units.
Your
dealer
will
be
glad
to
advise
you.
Mains Connection
The
set
is
designed
to
operate
from
an
AC
mains
supply
of
220
V
(50/60
Hz).
Additional
Information
for
sets
sold
in
Great
Britain
The
set
is
designed
to
operate
from
a
mains
supply
of
240
V
AC.
We
recommend
that
a
13
amp
3-pin
plug
fitted
with
a
2
amp
fuse
be
used.
The
brown
lead
should
be
connected
to
the live pin (marked ’L’ or ‘red’ or
‘brown’)
and
the
blue
lead
must
be
connected
to
the
neutral
pin
(marked
'N’
or
’black’
or
’blue’).
On
no
account
should
either
of
the
wires
be
connected
to
the
earth
pin
(marked
’E’
or
’green/
yellow’). If other mains plugs are
used,
ensure
that
they
are
protected
with
a
2
amp
fuse.
We recommend that the set be
disconnected
from
the
mains
when
not
in use for long periods.

Aerials
In primary service areas good results can
be obtained on FM with a simple room
dipole eg: GRUNDIG FM strip dipole.
For the best possible results we
recommend the use of an outside FM
dipole especially when receiving stereo
broadcasts. Remember 10 times as much
aerial signal is required when receiving a
stereo transmission. Even an outside FM
dipole may not be suitable in mountainous
regions or for long distance reception
unless it is mounted as high as possible
above the roof of the house.
On the back of the unit there are flat
sockets for aerials and earth (pos. @). The
sockets |[ are for connecting an FM
dipole (300 2). When an outside FM dipole
is used, AM (LW, MW) reception may also
be improved, if the shorting link is inserted
horizontally between the two upper flat
plug sockets (see detailed drawing, page 3).
lf separate outside aerials for FM and
MW/LW are being used, the shorting link
must be inserted vertically between the
flat plug sockets (blind connection), other-
wise inter-action between the two aerials
will
occur.
|
The high-impedance socket Y is intended
for the connection of an external AM aerial.
A 75-ohm aerial system can be connected
to the coaxial socket @. In addition to FM
it serves also for AM, when the shorting
link is inserted horizontally between the
AM aerial socket Y and FM socket
(as above). |
If you are not sure of signal conditions
in your area, and remember that a good
signal is essential for optimum stereo
reception, we suggest you contact your
dealer who will be pleased to advise you
as he will be familiar with the conditions
for reception in your area.
Loudspeakers
To achieve the best results we recommend
that you choose GRUNDIG HiFi Loud-
speaker Enclosures as these are of the
highest quality and capable of handling the |
full output power of the unit.
On the rear of the set, connecting sockets
for two separate stereo loudspeaker
groups are provided (pos. @, €). These
speaker groups (LS 1 and LS 2) can be
Operated simultaneously in two separate
rooms. The loudspeaker impedance must
be 42 to obtain full power output. It is
permissible, however, to use loudspeakers
with an impedance of up to 16 Q provided
that the loss of output power experienced
is tolerable.

Always make sure that the right-hand
loudspeaker unit is connected to the RH
socket and vice versa.
Overload Protection
The circuit has been designed so that it will .
sense open and short circuit loading conditions.
It will also sense over capacitive or over
inductive loads and the automatic overload
protection circuit will then operate. Thermal
protection devices have also been fitted to the
mains input transformer and onto the heatsinks
of the output transistors. These transistors
are therefore protected against destruction by
overload and high operating temperatures. Should
a fault condition occur these overload protection
circuits will reset themselves when the fault has
been cleared.
An electronic loudspeaker protection circuit
prevents the destruction of the loudspeakers
should a fault occur in the power amplifier.
Switching On and Off
The
set
is
switched
on
and
off
by
means
of
the
toggle
switch
“POWER*“
(pos.
@):
Bottom
=

of
the
human
ear
as
the
sound
intensity
is
reduced.
As
the
volume
control
is
reduced
through
medium

VHF/FM Field Strength Indication €
The LED array can be very useful on
VHF/FM for indicating the field strength.
Where it is possible to receive several
identical stations of varying strength, the
set should be tuned to the transmitter which
gives the highest field strength reading,
especially where stereo transmissions are
to be received. It cannot be emphasised
too much that stereo radio requires a much
higher aerial input signal than for the same
programme in mono.
For the technically minded: — the minimum
signal, recommended for this unit.
for satisfactory stereo reception, is 25 uV.
Below this figure one can expect
a deterioration in signal to noise ratio.
O - 4 =
10 uV 200 WwW SMV
The aerial voltages quoted are approximate
values in 300 9.
Tone
The bass, medium and treble tones can be
adjusted separately and independently
using the controls @, © and @.
Stereo Balance Control!
The relative output between left and. right
loudspeakers can be adjusted with the
balance control @. The contro! can be
used to compensate for poorly positioned
loudspeakers or unfavourable room -
conditions.
Headphones
Connecting sockets for two stereo
headphones are located in the front panel
of the unit (pos. ®). Headphones with a
6.3-mm jack plug and an impedance of
8 to 2000 ohms are suitable, in particular
GRUNDIG stereo headphones which are
matched perfectly.

Record Player Connection (DIN)
For connecting a record player with
magnetic
pick-up,
socket
@
on
the
rear
of
the
set
is
provided.
The
set
incorporates
a
separate
pre-amplifier/equalizer
so
that
a
separate
equalizer
is
not
necessary.
For
connecting
a
record
player
with
magnetic
system
and
combined
pre-
amplifier/equalizer
or
ceramic/crystal
cartridge,
the
sockets
@
and
®
are
provided.
For
record
reproduction,
depress
the
corresponding
button.
With
the
switch
@
on
the
back
of
the
set,
it
is
possible
to
change
the
input
sensitivity
of
socket
TA/Phono
@.
When
this
switch
is
set
to
position
“High“,
the
sensitivity
is
of
a
value
that
corresponds
to
the
current
DIN
regulations
and
the
Standards
of
the
record
manufacturing
industry.
When
setting
switch
@
to
position
“Low“,
the
gain
factor
is
attenuated
by
approx.
6
dB
(approx.
the
half).
By
this,
an
improved
stability
against
overmodulations,
which
are
frequently
encountered
when
playing
highly
modulated
records
(as
for
example
direct-cut
records)
or
when
using
pick-ups
delivering
high
output
voltages,
is
obtained.
Same
switch
can
also
be
used
to
compensate
for
volume
differences
between
the
individual
sound
sources
(radio,
record
player,
tape
recorder).
Tape
Recorder
Connection
(DIN)
The
Sockets
@)
and
@
on
the
rear
of
the
set
can
be
used
to
connect
tape/cassette
recorders
for
both
record
and
replay
or
to
rerecord
from
one
machine
onto
the
other.
The
two
sockets
are
equivalent
and
are
switched
into
circuit
with
the
button
TB
1
or
TB
2.
For
playback
or
rerecording
select
the
TB
socket
to
which
the
reproducing
tape/cassette
recorder
is
connected.
An
additional
socket
TB
2
@
is
located
in
the
front
of
set.
This
socket
is
selected
with
the
button
TB
2.
When
nothing
is
connected
to
the
rear
socket
TB
2
(pos.
@),
the
front
socket
@
offers
the
same
possibilities
as
the
rear
socket.
If
the
rear
tape
socket
is
occupied,
then
the
front
socket
@
should
be
used
for
recording
only.
Rerecording
between
the
front
socket
@
and
the
rear
socket
TB/TAPE
1
(pos.
@)
is
always
possible.
Please
see
also
the
operating
instruction
of
the
tape/cassette
recorder.

Via Tape Monitoring
This
set
is
provided
with
a
monitor
socket
(pos.
&))
which
permits
via
tape
monitoring
when
recording
onto
a
tape
machine
being
designed
for
monitoring
operation.
Connect
the
Monitor
socket
with
a
standard
lead
(e.
g.
GRUNDIG
lead
242)
to
the
corres-
ponding
socket
on
the
tape
machine.
If
you
now
set
the
Monitor
switch
@
to
its
bottom
position,
the
recording
is
continued
without
interruption, but the receiver amplifier is
connected
to
the
playback
contacts
of
the
Monitor
socket
and you
will
hear
the
just
recorded
signal.
By
setting
the
Monitor
switch
repeatedly
to
its
top
and
then
to
its
bottom
position,
you
can
compare
the
just
recorded
programme
with
the
original
programme,
and
thus
check
the
recording.
Line Output Socket
Socket LINE €D is a low impedance/high
level voltage output for making high
quality
recordings
on
a
tape
recorder
with
a corresponding line input socket. It is also
possible
to
connect
a
mixer
or
reverber-
ation
unit
to
the
Line
output
and
play
back
via the Monitor socket with the receiver
being switched to Monitor operation
(MONITOR switch @ set to bottom
position).
The
Line
output
socket
can
also
be
used
to
feed
another
amplifier
or
