Harman Kardon CD 401 - HX-PRO System; Erasing the Recorded Signals; Timer Function

,-HX-PRO System-
By varying the bias level to compensate for the dif¬
ferent characteristics of the input signal. Active Bias
is kept constant, so that this allows natural-sounding
recordings of the low frequency region. Also, much
higher levels of high frequencies can be recorded.
If we consider specific sectors of the frequency range,
then, if a signal source only contains high frequency
components, the HX-PRO will detect this and reduce
the bias from the oscillator to the optimum bias for
the signal. On the other hand, no changes in bias level
will be made for signal sources that contains only low
frequency sounds. However, when low frequency sig¬
nals contain occasional admixtures of high frequency
signals, the HX-PRO will reduce the bias, changing
only high frequency bias levels while keeping lower
frequency bias level constant. The new system, there¬
fore, not only offers an improvement at high frequen¬
cies, but also ensures the optimum bias at low fre¬
quencies, too.
Advantages of the HX-PRO
| 1. Gives performance almost equal to metal tape for
normal tape.
| 2. Outstanding treble dynamic range.
| 3. Adjustment to left and right channels can be
made independently.
I 4. All kinds of tape from normal through metal are
suitable.

Erasing the Recorded Signals
When a new recording is made on a recorded tape, the
recorded sound on that part of the tape is automatically
erased. To erase the recorded sound on the tape without
recording, operate as follows:
1. Be sure that erase-prevention tabs of the cassette are
not broken out. If broken, cover the holes with ad¬
hesive tape.
2. Turn the LINE INPUT LEVEL controls to the 0 posi¬
tion and MICROPHONE INPUT LEVEL controls to
the MIN position.
3. Press the BIAS selector buttons corresponding to the
type of the tape.
4. Press the RECORD and PLAY buttons at the same
time.
Timer Function
By using an audio timer, FM broadcasting can be automati¬
cally recorded or the tape can be automatically played back
at any desired time while you are out or sleeping
Therefore, this function can be conveniently used instead
of an alarm clock.
Automatic recording while you are out
1. Connect the AC cords of CD401, tuner and amplifier
to the timer.
2. Turn the POWER switches of CD401, tuner and
amplifier ON and then select a desired broadcasting
station.
3. Make necessary ad¬
justments in recording
levels reffering to the
explanation for Tape
Recording. After that
press the TIMER REC
button.
4. Preset the timer to a desired time. With this power
supply is turned off except the timer.
5. At the preset time, power supply to CD401, tuner and
amplifier is turned on and then tape recording starts
after about 2 seconds. At the tape end, operation of
CD401 stops by the Auto Stop mechanism and then
power supply is cut off by the timer.
Caution: 3e sure to adjust the VOLUME knob of the
amplifier to the minimum setting position so that music or
other item being recorded will not be reproduced by the
speakers.
Automatic tape playback for morning wake up
1. Connect the AC cords of CD401, tuner and amplifier
to the timer.
2. Turn the POWER switches of CD401 and amplifier
ON.
3. After setting a cassette tape in the CASSETTE COM¬
PARTMENT, press the proper EQUALIZATION
selector button and adjust the OUTPUT LEVEL
control.
4. Press the TIMER
PLAY button. The
TAPE MONITOR
switch must be in the
MONITOR position.
5. Preset a desired time
on the timer.
Caution: For normal operation, press the TIMER OFF
button without fail.
Caution
Do not tamper with the adjusting knobs marked DOLBY
NR PLAYBACK CALIBRATION on the rear panel. Since
they have been set to the standard Dolby level at the
factory, tampering with these knobs will disable correct
recording and playback through the Dolby NR systems.
If playback sound through these systems is not proper,
ask your retailer or send the unit back to Harman Kardon
for adjustment.
