troduction
,is recorder can be used with ferro, chromium and metal
cassettes. To improve the signal-to-noise ratio the recorder is
provided with the Dolby* NR (Noise Reduction) system.
* Trademark of Dolby Laboratories.
The mechanism is operated by micro switch buttons; the switch
functions are activated by solenoids. The recorder mechanism is
equipped with two motors, one of which is a tacho controlled
direct drive capstan motor.
Instead of the usual two heads, this recorder has three heads
(Fig. 7 - ®, © and ©). The separate heads for recording and
playback are situated together in one housing. Separate heads
provide the possibility of 'off-tape' monitoring (playback during
recording) and more accurate adjustment of the recording level.
The automatic repeat facility enables continued playback of a
cassette as many times as required.

Note: Do not expose the recorder for any great length of time to

cessive heat from heating equipment or direct sunshine.
Connecting the recorder to the mains
Before connecting the recorder to the mains ensure that voltage
selector sa is set to the local mains supply. If it is not, turn the
voltage selector until the correct voltage value is indicated. After
Important note for users in U.K.
When fitting a mains plug to the mains lead proceed as follows: The
wires in the mains lead are coloured in accordance with the
following code: Blue = Neutral, Brown = Live. As these colours
may not correspond with the colour markings identifying the
terminals in your plug proceed as follows:
The Brown wire must be connected to the terminal which is
marked with the letter L or coloured Red. The Blue wire must be
connected to the terminal which is marked with the letter N or
coloured Black.
Note: This apparatus must be protected by a 3 Amp Fuse if a
13 Amp plug is used or if any other type of plug is used by a 5 Amp
Fuse either in the plug or adaptor or at the distribution board. If in
doubt consult a qualified electrician.
Switching on and off
• Switching on: Press mains switch ®, the recording level
indicators zi and® and the cassette holder® will now light up.
• Switching off: Press mains switch is again.
Compact cassettes
• With compact cassettes you can make stereo and mono
recordings. At anytime, the cassette can either be turned over and
the other side used, or it can be replaced.
• Both ends of the tape are attached by a length of non-magnetic
leader tape to the reel hubs. It is therefore necessary when starting
at the very beginning of the tape to allow the cassette to wind on
for about seven seconds before starting to record.
• You can prevent the accidental erasure of recordings as
follows:
Having made the recording, take a sharp object and break out the
little flap at the left-hand corner at the back of the cassette (Fig. 3).
With the cassette in the recorder at any time thereafter, no
recordings can be made on the side concerned.
• You can render this safeguard ineffective by covering the
aperture now existing with a piece of adhesive tape.
• Musicassettes are compact cassettes containing prerecorded
music. They are safeguarded against accidental erasure.
• Protect your cassettes against dust by returning each to its box
after use. Store the cassettes at room temperature, away from the
sun and out of magnetic fields generated by magnets and trans-
formers of recorders, radios, television sets, loudspeaker en-
closures etc.
Inserting and removing the cassette
• Inserting: Press eject key®; ; the damped cassette holder®
will now open. With the full reel on the left-hand side, slide the
cassette fully into the holder as shown in Fig. 4. Close the cassette
holder. Stop indicator® now lights.
• Removing: Press eject key®; ; the cassette holder® will open
and the cassette can be removed.
Note: Eject key® also serves as a stop key.
Adjustment for type of tape in use
In the magnetic recording and playback of sound, it is necessary
to employ a certain standardized frequency correction, known as
equalisation.
Also, during the recording process it is necessary to apply the
correct bias (pre-magnetisation) according to the type of tape in
use.
During recording, switch ® must be set according to the type of
tape. Switch ® adjusts both the recording equalisation and the
bias.
During playback, switch® must also be set according to the type
of tape. Switch ® adjusts only the playback equalisation.
The correct equalisation for a particular cassette will normally be
indicated on the cassette, and is expressed in microseconds e.g.
EQ-120 µs.
Note: Do not confuse the figure for equalisation with that of the
