Aerials
In primary service areas good results can
be obtained on FM with
dipole eg: GRUNDIG FM strip dipole.
For the best possible
recommend the use of an outside
dipole especially when receiving stereo
broadcasts. Remember
aerial signal is required when receiving a
stereo transmission.
dipole may not be suitable in mountainous
regions or for long distance reception
unless it is mounted
above the roof of the house.
On the back of the unit there
for aerials and earth (pos. O), The
sockets are for connecting an FM
dipole (300 Q). 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).
If separate outside
MW/LW are being used, the shorting link
must be inserted vertically
flat plug sockets (blind connection), other-
wise inter-action between the two aerials
will occur.
The high-impedancesocket Y is intended
for the connection
A 75-ohm aerial system can be connected
to the coaxial socket O. In addition
it serves also for AM. when the shorting
link is inserted horizontally

If you are not sure Of signal conditions
in your area. and remember that a good
signal is essential for optimum
reception, we suggest you contact your
dealer who will be pleased to advise you
as he will be familiar
for reception in your area.
Loudspeakers
To achieve the best results
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
for two separate stereo loudspeaker
groups are provided (pos.

rooms. The loudspeaker impedance must
be 4 Q 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

socket and vice versa.
Overload Protection
The ci rcuit has been designed

It Will also sense over
inductive loads and the automatic
protection circuit Will then operate. Thermal
protection devices have also been titted to the
mains input transformer and onto the heatsinks
of the output transistors. These transistors
are therefore protected

An electronic loudspeaker protection circuit
