4D dbx button
When recording with dbx NR, input signals with a large dynamic range
are compressed to 1/2, and expanded by a factor of 2 to their original
state when played back. This means that a large dynamic range can be
obtained even from cassette tapes with small dynamic range recordings,
and noise can also be reduced at the same time. If metal tapes are used
for recording and playback, a dynamic range which would have been
thought impossible with cassette tapes can be obtained. For recording

3-HEAD CONFIGURATION AND AUTO MONITOR SYSTEM
This unit uses a full-scale three-head configuration, with independent
recording, playback and erase tape heads, as well as independent
recording and playback amplifiers. Sint;::ea major characteristic of a
three-head tape deck system is simultaneous tape recording and tape
playback, tapes can be monitored directly as they are made.
The auto monitor function automatically switches to source monitor
during the rec/pause and recording, and to tape monitor during the
playback. The auto monitor function can also be manually switched by
using the MONITOR button if required (tape monitor during recording).
DOLBY C TYPE NOISE REDUCTION
same noise reduction effect at both high and low signal levels and to set
the recording level at a point where side effects such as "breathing" are
eliminated. Also, by expanding the operating frequency range to two
octaves more than that of Dolby B NR, overall noise balance is obtained
and the system also becomes effective against high frequencies from the
power supply.
The graph shows the frequency response and the noise reduction effect
of recording and playback with Dolby B NR and Dolby C NR. The noise
reduction effect of Dolby C NR is larger - approximately 20 dB.
Dolby noise reduction is a 2 part process that acts both on recording and
playback; be sure that the noise reduction button is set to the same
position on record and play.
*Noise in the source material cannot be reduced with the Dolby NR
system.

Frequency (Hz)
With cassette tapes, the most noticeable form of noise is high frequency
hiss. To reduce this hiss noise, the KX-800/U has been equipped with
Dolby Band C noise reduction systems. Either type of noise reduction
may be selected with the switch provided.
Dolby B NR has a noise reduction effect of about 10 dB in the high
frequency range. The corresponding figure with Dolby C NR is about 20
dB, but this is over the entire range where the human ear is most
sensitive to noise (2 kHz to 8 kHz). Dolby C NR also improves the tape's
MOL (Maximum Output Level).
Dolby C NR has two circuits; a spectral skewing circuit and an anti-
saturation network. By improving the saturation level of the tape it is
possible to prevent high frequency loss and encode/ decode error, etc.,
improve dynamic range and signal-to-noise ratio, and make it easier to
set the recording level. With Dolby C NR it is possible to achieve the

HX PRO DYNAMIC BIAS SERVO SYSTEM
Dolby Noise reduction and HX Pro headroom extension manufactured
under license from Dolby laboratories Licensing Corporation. HX Pro
originated by Bang & Olufsen.
With this system, the deterioration of the high frequency signal
components has been drastically improved, resulting in dynamic and
clear recording with sufficient headroom. The circuit works independently
on each channel, and no decoding is necessary during playback.
*The HX Pro is not the noise reduction system, Since it functions only in
recording, the tape recorded with HX Pro system can be played back
on any types of cassette decks, with a richer dynamic range.

ENCODE Tape's full capacity level DECODE
The built-in dbx system works by compressing the dynamic range of the
record signal by half and then doubling the dynamic range of the playback
signal, resulting in expande dynamic range of cassette tapes.
With the dbx system functioning, a program source compressed to 50 dB
at recording will be expanded to a dynamic range of 100 dB. At the same
time, noise levels will be reduced throughout the entire frequency range,
and the effective saturation level of the tape will be increased.
*Tapes not recorded with the dbx system should be played back with the
dbx system off.

It is important that the optimum bias current be supplied to the recording
head during recording. However, an excessively high bias current with
cause the loss of the high frequency range and an excessively low bias
current will cause the distorted sound.
In addition, the high frequency content of the recording signal tends to act
as bias upon itself, and it becomes difficult to carry out recording with the
optimum bias. To prevent this, the HX Pro Dynamic Bias Servo System
constantly monitors the recording signal and instantly decreases the
increased bias to keep the total effective bias constant.

5. After completing bias adjustment, press BIAS TEST switch to off. The
tape will be rewound to the beginning of the bias adjustment.
• If the heads are dirty or the tape is unsatisfactory, etc., it may not be
possible to carry out bias adjustment.
• When the BIAS TEST switch is ON, ordinary recording and playback
cannot be carried out.

both the KX-800/U and your amplifier (receiver, etc.) are turned off
before making connections.

ICASSETTE TAPES "' I
• CASSETTE TAPES
There are many different types of cassette tapes available, however, they
all conform to standard specifications so any brand may be used with the
KX-800/U.
*Classification of Cassettes Tapes by Formulation
Cassette tapes are available in four basic types depending on their
formulation, or type of magnetic material and manufacturing process.
These four types are commonly known as Normal (II NORM), Chrome
(1I/Cr02), Ferrichrome (1II/FeCr), and Metal (IVIMETAL), and they
each require specific optimum performance.
The KX-800/U has an Auto Tape Selector which automatically adjusts
for the proper bias, level and equalization according to the tape
formulation - all you have to do is load a cassette and the Auto Tape
Selector does the rest.
*Old-type Metal tape cassette shells do not have the necessary hole for
Auto Tape Selector operation. It is recommended that you do not
record with this kind of Metal cassette. However, Metal tape cassettes
recorded on another deck may be played back with the KX-800/U at
the Chrome (IIICr02) settings. All current cassette tapes will have this
small opening in the cassette shell, so be sure you use suitable
cassettes with the KX-800/U.
*The KX-800/U does not have the required setting for Ferrichrome (1111
FeCr) tape, since this tape formulation is not widely used. Should you
use a Ferrichrome tape, it will be recorded and played back at the
Normal (I/NORM) settings. And this will result in an unnatural high
frequency emphasis. This effect may be compensated for somewhat
by adjusting the tone controls of your amplifier.
*YAMAHA does not recommended the use of C-120 cassettes since
the extreme thinness of the tape makes them susceptible to
mechanical and electrical problems.
-.
• PROTECTING YOUR RECORDINGS
~=,c=.
~
~
All cassette tapes are provided with erasure protection holes to prevent
recorded tapes from being accidentally erased. There is a small tab
covering the hole on each cassette, and it should be broken off with the
screwdriver after recording a tape. Without this tab covering the hole, it is
impossible to record on that tape again; thus, you can keep any recorded
tape for as long as you wish without fear of accidental erasure. Should
you wish to use a cassette tape protected in this way for later recording,
simply covering the hole with adhesive tape will permit erasure and re-
recording.
* When using Chrome (1I/Cr02) or Metal (IV/METAL) tape, make sure
you do not cover the hole intended for the tape formulation check.
14

• TAKING UP SLACK IN THE TAPE
Slack in the tape inside of the cassette shell can be corrected by simply
inserting a pencil into one of the spools and winding it until all the slack is
taken up.
• STORAGE OF YOUR CASSETTE
