O BIAS FINE Tuning Control
This control allows fine bias level setting
when recording. The center “click” position
provides a nominal amount of bias current
depending on the type of tape.
Turning the control toward + increases the
amount of bias and thus decreases high
frequency response.

In this mode, tape travel is measured in
increasing minutes and seconds up to a
maximum of 99.59 (99 minutes 59 seconds).

Type Indicators
This meter shows the peak level of the
input or playback signal. In the record
mode, the meter indicates the level of the
source signals which have been adjusted
with the Recording Level controls. The
highest peak to be recorded should generally
not exceed the meter reference reading for
the type of tape used.
During playback, the meter indicates
the level of signals recorded on the tape.
The deck automatically detects the type
of tape which has been loaded, and these
indicators (NORMat, Ér0, and METAL)
indicate the type of tape being used.
A dash indicator below the appropriate
tape type indicator is provided as the
meter reference reading for the type of
tape used.

Recording prerecorded tapes, recdrds, or

laws before recording.
Setting the recording level correctly is
essential if you want to make top-quality
recordings. If the level is too low, the
recording will be noisy. [the level is set too
high, the recording will be distorted.
Generally speaking, the recording level
should be set so that the loudest peak to be
recorded makes the meters briefty indicate
the meter reference reading for the type of
tape used. If the meters peak over the
reference reading, decrease the recording
level by turning the Recording Level con-
trols counterclockwise. However, some pra-
gram material of different tape formula-
tions may require higher or lower record-
ing levels. With a little time and practice
you will be able to select the critical record-
ing level that gives you the best hi-fi re-
cordings. The type and condition of the
tape, as well as the type of music source
you are recording will affect the optimum
setting of the recording level.
The capability of creating blank unrecorded
(erased) portions on a tape during recording
is a real advantage in many recording situa-
tions. Fer instánce, you may want to
eliminate undesired portions of an FM
broadcast that you are recording, such as
commercials, station breaks or announce-
ments, You may want to record a complete
program with controlled spacing between
each song. Such blank portions on à tape
can be easily left using the REC MUTE
1. Automatic Spacing Operation — for a 4-
second blank — (during recording or
record-pause mode)
Press the REC MUTE button during
recording or record-pause mode. The
tape movement continues, and a blank
space of about 4 seconds is recorded
{the REC indicator flashes).
The deck then switches automatically
to the record-pause mode (both the
REC and PAUSE indicators light),
To begin recording the next tune, press
the » button (the PAUSE indicator -
goes off).
2. For a Blank of More Than 4 Seconds
During recording, keep the REC MUTE
button pressed for a longer blank period.
Release the button to enter.the record-
pause mode. To begin recording, press
the » button.
3. Fora Blank of Less Than 4 Seconds
After pressing the REC MUTE button
during recording, press the PAUSE
button, before the 4-second interval has
expired, to cancel the muting mode and
“ engage the record-pause mode. To begin
recording, press the № button. .
A previously recorded tape will be auto-
matically erased -when you make a new
recording on it. Alternatively it can be
erased by “recording” on it with the
MASTER REC LEVEL control set to “0”,
‚Punch; ln Recording = о оллЬь
During playback, you can go from repro-
duce to record by holding in the RECORD
button and simultaneously pressing the »
button. A new recording will start from that
location, This operation allows you to re-
cord over or correct a recorded section of
the tape without pressing STOP button
first and then enabling the record mode.
Deck-to-deck copying of tapes (dubbing)
can be done without using an external am-
plifier. Operation is the same as standard
record and playback procedures described in
the record and playback sections.
This deck can be used as the “master” re-
corder with a second recorder used as the

:Multi-Counter Function.
With the multi-counter facilities incorporat-
ed in the unit, there are two different
display modes available, depending on the
setting of the COUNTER MODE button.
Tape Counter Mode: The counter functions
as a conventional tape counter.
TRT Counter mode: The counter functions
8$ а tape-run-time counter, measuring tape
travel in minutes and seconds,
Using as a Tape Counter
Using the COUNTER MODE button, call up
the tape counter mode; a 4-digit display will
appear. lts function is identical to that of
conventional tape indexing counters. Dur-
ing recording (included record muting},
playback and fast-forward, the counter
counts upwards as the tape moves from
left to right, and downwards during re-
wind as the tape moves from right to left.
The indicated numerals are not related to
time lapse and are not compatible with
the counter readings of other cassette
decks. One typical example of using this
display in the conventional tape counter
mode is: First load a cassette and before
recording, press the COUNTER CLEAR
button to reset the counter to “0000”.
Then note the counter reading at the begin-
ning of each piece of music to facilitate
locating a particular selection when you
wish to play it back,
Using as a TRT Counter
Using the COUNTER MODE button, call up
the tape-run-time mode: a dot appears
between the 2nd and 3rd digit: In this
mode, tape travel is measured in increasing
minutes and seconds while. the tape is
running at norma! speed during recording
{including record muting} and playback.

forward. This function can be used to
measure the approximate length of a re-
corded song or to make a calculated estima-
tion of how much tape is left.
“Visible” and “invisible” Counters
Both counter modes are switchable at any
time, with the one selected appearing on the
display and the other functioning in mem-
ory. For example, when the conventional
tape counter is selected with the COUNTER
MODE button, counting of the tape-run-
time also takes place and its reading can be
called up at any time by pressing the COUN-
TER MODE button, Pressing the COUNTER

Dolby HX Pro is an “active bias” technique
that can improve the quality of audio tape
recordings. High-level high freguencies can
be recorded more accurately, without
sacrificing signal-to-noise ratio, while such
side effects of tape saturation as distortion
are reduced.
What Is Bias?
Bias is a very high-frequency signal generat-
ed within a tape deck and recorded on the
tape simultaneously with the program
material, This inaudible signal allows a low -
noise, low distortion recording and flat
frequency response, Different magnetic tape
formulations require different amounts
of bias for optimum performance, If the
bias level is too high, high-frequency
Maximum Output Level MOL) decreases.
The Problem of Self-Bias
Unfortunately, bias level is often influenced
by the signal being recorded. The high fre-
quencies contained in some music act as
hias. This unpredictable source of bias is
added to the existing bias, resulting in a loss
of high-frequency response, As the high-
frequency content of the signal increases,
the ability of the recorder to record high
frequencies (MOL) decreases, This pheno-
menon is called self-biasing.
20Hz 50 100 200
How Dolby HX Pro Solution |
The Dalby HX Pro manitors the high-
frequency content of the program material
and adjusts the recorder bias oscillator to
maintain a constant total bias level. The
result is improved high-frequency response
and lower distortion. Depending an the type
of tape, the improvement in headroom can
be 6 dB ar more,
The Benefits
With Dolby HX Pro, it is easier to make
more accurate recordings of the kind of
music which contains high-level high fre-
quencies, The improvement is similar 10
that of high-performance tape over conven-
tional tape, so regardless of the type of
tape used, the results will sound better,
Most important of all, Dalby HX Pro
requires no “decoding process, Once the
tape is recorded with Jt, the improvements
will be realized when playing the tape back
on any machine.
