Tone
The bass and treble tones can be adjusted
separately and independently using the
controls @ and @.
Low Pass Filter
If the lever switch @ is moved to the top
the filter is operative. With the filter switch-
ed on all frequencies above 7 kHz are
suppressed. The filter is particularly useful
for removing high frequency hiss or distor-
tion (noisy tapes or old gramophone
records).
Linear/Contour Switch
(loudness compensation)
The contour facility is to compensate for
the change in frequency response of the
human ear as the sound intensity is re-
duced. As the volume control is reduced
through medium to low volume the bass
and high frequencies are progressively
boosted to alter the tonal balance.
!f the lever switch @ is moved to the LIN.
position no treble or bass boost will take
place as the volume is reduced. We
recommend the switch @ be used in the
linear position when large loudspeakers
(having superior bass respons) are used
and also when speech is being reproduced.
For all other conditions we recommend
the switch be set in the CONT. position.
Balance Stereo Control
The relative output between left and right
loudspeakers can be adjusted with the
balance control @. The control can be
used to compensate for poorly positioned
loudspeakers or unfavourable room
conditions.
Record Player
The built-in record player is fitted with a
magnetic cartridge wired internally to the
amplifier. To replay a gramophone record
the TA button @ must be pressed.
Please read the record player instruction
book carefully.
The set is permanently wired for stereo
operation, but when a mono gramophone
record is played it will automatically be
reproduced in mono through both loud-
speakers.
The built-in Cassette Recorder
is ready for use as soon as the complete
set is switched on with the mains switch @
(top position of switch).
To replay a cassette the CASS button ©
must be pressed. To record onto the
cassette select the required programme
source, by pressing the corresponding
programme button: TA = built-in record
player, TB = external tape recorder, cas-
sette recorder or record player, UKW/LW/
MW/KW = desired radio programme.
When replaying a mono cassette it will
automatically be heard from both speakers
in mono.
TB Socket (Universal socket)
The TB socket ® on the rear of the set
can be used to connect a tape recorder or
a cassette recorder for both record and
replay. Recordings can be made from the
internal cassette recorder to an external
tape / cassette recorder or vice versa both
in stereo and mono. For connection use
the radio socket (or equivalent socket) on
the external tape or cassette recoder.
The TB socket can also be used for con-
necting an external record player fitted
with a ceramic or crystal cartridge (or a
record player fitted with a magnetic
cartridge and pre-amplifier).
The TB button @ must be pressed to re-
play or to record onto the built-in cassette
recorder any signal presented to the TB
socket. As previously mentioned all mono
signals available from equipment accord-
ing to modern standard will be replayed
through both jeft and right hand channels,
however to ensure signals from equipment
of older standard are replayed through
both left and right hand channels (in
mono), the Mono-button @ must be de-
pressed. Do not forget to release this
button when connecting stereo equipment.
Before connecting a tape recorder or
cassette recorder to the TB socket be sure
to read the instruction book supplied with
the product carefully.
Simultaneous Rerecording
During radio reception ard replay of
records, it is possible to record the cor-
responding programme (radio or record
replay) simultaneously onto the built-in
cassette recorder or — via the Tape socket
® — onto an external tape/cassette
recorder.

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. Shou:d
a fault condition occur these overload protection
circuits will reset themselves when the fault has
been cleared.
