Noise
Reduction
System
(DOLBY
NR)
Always
play
back
a
cassette
in
the
same
way
as
it
was
re-
corded,
ie:
record
and
playback
should
be
both
with
or
without
DOLBY
NR
(B-type
or
C-type)
selected.
It
is
only
under
these
conditions,
that
playback
quality
will
be
op-
timum.
The
advantage
of
recording
with
DOLBY
NR
over
recording
without
DOLBY
NR
is
a
noticeably
better
signal-to-noise
ratio,
ie:
the
ratio
of
the
volume
of
the
useful
signal
(eg:
music)
to the inherent noise. :
B-type
or
C-type
NR?
The
“DOLBY
C-type
NR
system”
Is
a
further
development
of
the
“DOLBY
B-type
NR
system”
with
better
noise
reduction
over
a
wider
frequency
range.
For
this
reason,
always
select
the
C-type
NR
when
making
new recordings.
lf
a
commercially
pre-recorded
cassette
only
shows
the
OO
symbol,
the
recording
was
made
with
the
DOLBY
B-type

@ To stop playback press the stop button 1.
Fast Wind
®@ For fast rewind: press button <i.
@ For fast forward wind: press button>>.
@ To stop fast wind: press stop button (1.
Tape-End Switch-Off
The unit automatically switches to stop in all tape running func-
tions when the end of tape is reached.
Recording
Warning:
Copyright — in copying 4 material copyright must not be infringed.
Preparation for Recording
The unit must be correctly connected and ready for operation;
the same applies to the programme source (eg: tuner, record
deck, etc.). |
® For recording with or without DOLBY NR (B-type or C-type),
press the DOLBY B-C NR button as appropriate (see section
headed “Noise Reduction System’).
@ Press record button REC/MUTE: the unit switches to record-
ing/pause, as can be seen in the display.
— \f a cassette protected against erasure is inserted, no record-
ing will be possible (see also section headed ee and
Protecting Against Accidental Erasure’).
— If the unit is set to the function TAPE (indication TAPE), ewitch
to indication SOURCE with the SOURCE/TAPE button, to
enable you to check the recording level with the aid of the re-
cording level indication.
® lf you record without tape matching, turn the BIAS and CAL
controls to their centre positions.
Adjusting Recording Level
@ Turn the MASTER CONTROL fully right.
@ Adjust the small LEVEL controls so that the O-dB marks of
the level indication just light up at the loudest points in the re-
cording (0 dB = maximum recording level).
The recording level for the two channels can be adjusted sepa-
rately to equalise different stereo levels, eg: in the case of rere-
cordings. In general, however, it is not advisable to change the
stereo balance but to set the LEVEL controls for the same re-
cording level using the adjustment figures.
Lighting up of the level indication above the 0-dB marks (+B)
indicates over-modulation and should only happen for very
short periods. |
Start Recording
by pressing the start button >.
Monitoring During Recording
Recordings can be monitored through an anipiinee connected
to the LINE OUT sockets or via the HEADPHONES socket.
Pre-Tape Monitoring (Monitor A)
To monitor the sound as it is being recorded, switch to display
indication SOURCE using the SOURCE/TAPE button.
Off-Tape Monitoring (Monitor B)
To monitor the sound immediately after it is recorded, switch to
display indication TAPE using the SOURCE/TAPE button.
Fading Recording In and Out
@ To fade recording in: Gradually tum MASTER CONTROL
from “QO” to the point previously found to give correct record-
ing level.
® Jo fade recording out: Gradually turn MASTER CONTROL
down to “0”,
For Muted Recording
hold the © REC/MUTE button pressed during recording. No
sound will be recorded during this time, which allows eg: an-
nouncements to be faded out.
To Interrupt Recording
press the pause button 00.
To restart recording press the start button >.
To Stop
recording press the stop button 02.
MPX FILTER button
Press this button when recordings are made from an FM stereo
broadcast to filter out pilot tone residuals, particularly when
radio recordings are made using the DOLBY NR system.
Tape Counter
An electronic tape position counter with memory function is in-
tegrated in the display, which can be used as follows:
@ Rewind the cassette to the beginning of the tape.
@ Set the counter to “OO00” by pressing the reset (O-SET) but-
ton.
@ At the beginning of each recording note its title and the
counter reading.
@ On playback, set the counter again to “OOOO” after the cas-
sette has been rewound to the beginning of the tape.
— Any chosen title may now be selected observing the counter
reading.
The respective counter reading is retained when the unit is
switched off.
Memory Function
The MEMO button enables you to enter a stopping position in
the memory, which can then be called up via the rewind func-
tion (button <<).
To enter in memory
@ Press MEMO button: display shows MEMO.
To erase memory
@ Press MEMO button again or press 0-SET button.
Example:
@ Before the start of a recording, press the MEMO button; dis-
play shows MEMO.
@® Start recording.
@ If you do not like a number, press rewind button <<.
~ The recorder now winds the tape to the position (counter
reading) stored in the memory. From this point you can start a
new recording.

Calibration
For optimum operating point adjustment of the unit to the differ-
ent tape qualities, a test CD with different test tone recordings
is enclosed. The test signals required for the calibration are
supplied by the tracks 5 to 9 on the CD.
Adjustment
e Prepare the test CD for copying and insert a blank cassette.
@ Select the function recording/start.
@ The adjustment is made by means of pre-tape and off-tape
monitoring. Pre-tape means: you will hear the CD playback;
off-tape means: you will hear the sound already recorded.
— Switching between pre-tape and off-tape monitoring is done
with the SOURCE/TAPE button (pre-tape = indication
SOURCE, off-tape = indication TAPE in the display).
1. Copying track 8 (400 Hz) of the CD:
Adjust the LEFT CAL and CAL RIGHT controls in such a way
that no difference in volume level can be noticed between
pre-tape and off-tape monitoring. The O-dB mark in the re- .
cording level display should just light up (full modulation).
2. Copying track 9 (12 kHz) of the CD:
Adjust the LEFT BIAS and BIAS RIGHT controls in such a
way that no difference in tone can be noticed between pre-
tape and off-tape monitoring. The recording level display
should only light up to the -10dB mark.
Operation with an External Timer
It is possible to start and stop the recording function with an ex-
ternal timer.
@ Switch the cassette deck on with the POWER switch.
For Playback:
— Insert cassette and, if required, wind to the desired starting
position.
— Use the stepping button TIMER to switch to display indica-
tion [> TIMER: indication flashes.
For Recording:
— Insert cassette with sufficient playing time.
— Use the stepping button TIMER to switch to display indica-
tion REC TIMER {press twice): indication flashes.
@ After the respective preparations have been made, pull the
mains plug.
® Set the timer to the required switch-on and switch-off times
and connect the cassette deck to the timer.
Note: To switch off the timer function prematurely, press the
stepping button TIMER until the flashing TIMER function indica-
tions go out.
For normal operation of the unit, the timer function must be
switched off.
Erasing and Protecting Against Accidental
Erasure
Whenever a recording is made, any recording already on the
tape is automatically erased. Commercially pre-recorded cas-
settes are protected against accidental erasure.
You can protect your own
recordings against acciden-
tal erasure if you break out
the appropriate record lock
tab in the opening in the
back edge of the cassette
(eg: with a screw driver).
If you wish to make a fresh
recording, simply cover the
opening with a sticky tape.
Treatment of Cassettes
Never place the cassettes on or near radiators or any other
heat source as this may damage the tape and make the cas-
— gettes unusable.
When not in use, cassettes should be placed in their containers
to keep them clean and to prevent loops being formed in the
tape.
Care and Maintenance
To clean the cabinet, only a soft cloth which picks up dust
should be used. Aggressive polishing or cleaning materials may
damage the surface of the cabinet.
Consistently good recording and playback will be obtained only
if all parts with which the tape comes into contact, eg: pinch rol-
ler, capstan, sound head and erase head are free from tape ab-
rasion. They should be cleaned at regular intervals as follows:
® Open cassette compartment with EJECT button & and re-
move an eventually inserted cassette. =
e@ Soak a cotton wrapround in. methylated spirits and clean
parts making contact with tape. Do not use hard objects.
lf your set developes a fault, contact your dealer.
