enjoyment. To obtain the maximum benefit of the many features of this deck, please carefully read these operation
instructions.
1. Don't allow magnetic materials, such as a screwdriver or a magnet, near the head assembly. 2. When cleaning, be careful not to bend the tape
gu ides.
3. Don't attempt to clean the cabinet with alcohol,
benzine or thinner, because it may damage the linish. lf the cabinet is dirty, clean with a soft cloth dampened with a soap-and-water solution.

and playback with little distortion, the Tape selector should be set as shown in figure 5. Note that there may be a dillerence in sensitivity of 2 or 3 dB, depending on the type ol tape.
3. Power source
This unit features a DC operated motor which makes it possible to operate on 50 Hz or 60 Hz AC power lrequency without any conversion. The voltage source should be within +.5%o ol the unit's rated voltage. Variations in excess ol *.1OYo of ratedvoltage maycause uneven performance, or possible damage to the unit. 4. Clean the head assembly One of the most important factors in the determination ol good tape recorder perlormance is regular cleaning of the head assembly. 5. A "click" noise may be heard when the Power switch is turned on or off. To avoid this, be sure to set the volume control of the amplifier to the minimum position.
"Melal tape" (Refer to fig. 6.) Technological developments lo accomodate "Melal
tape"
"Metal tape" is a totally new kind of high perlormance tape, and conventional cassette tape decks cannot sulliciently bring out its performance potential. Our company has succeeded in developing the lollowing technology to exploit the advantages ol "Metal tape" to its
fullest extent.

1. Do not pull the tape out ol the cassette openings. 2. lf the tape is loose in the cassette, the tape may become wound onto the pressure roller and result in breakage or damage. Tighten looseness of the tape, if necessary, by using a pencil as shown in ligure 2. 3. Avoid using C-'120 cassette tape with this unit because this tape can easily become broken, stretched or twisted if not used with extreme care. 4. Avoid storing this unit in places where the temperature is high and/or where the humidity is high. 5. lf the tape is very tightly wound or unevenly wound, last forward it and then rewind it before use.
A word about "Metal tape"
Conventional cassette tapes can be broadly classilied into 2 categories according to the magnetic material coated on the tape surface: the lerric-oxide ( /-FezOo) type, including ordinary LH tape, etc.; and the chrome-dioxide (CrOz) type, including XA tape, etc. Continued technological advances have been made in an attempt to develop these tapes to a high level of performance, but recently there has been a recognized need tor the development ol a new material to improve perlormance much further. ln response to this need, "Metal tape" has been developed as a new kind ol tape, employing a magnetic alloy of pure iron (Fe) as lhe main component in the magnetic substance. ln comparison with conventional cassette tape, "Metal tape" can record a lar greater amount of information at a high
density. As a result, the maximum output level (MOL) has been improved throughout the entire range, and, in
MAINTENANCE (Refer to
lig.4.)
Because the Head assembly and the Capstan are in constant contact with the moving tape, dirt or residue lrom the tape on these parts will decrease the sound quality. They should be cleaned after every 10 hours of use, as shown in
figure
4.
particular, the frequency response characteristics at high levels and the dynamic range in the high range have been greatly improved. This means, theretore, that a remarkable improvement of sound quality has been made possible. (lt should be noted that the tape base and parts of the tape other than the magnetic substance are composed ol the same material as previously used.)
dbr Noise reduction system
The dbx Noise reduction system serves to greatly reduce the noise generated during recording and playback across the whole audible frequency spectrum (reduction by more than about "30 dB") and also to improve the linearity at high input levels. As a result, both recording and playback can be performed without impairing the wide dynamic range of the original sound. There are two kinds of dbx Noise reduction system: Type I and Type tr. Type I is used for open-reel decks and industrial applications while TypeII, which is features in this deck, is used for cassette applications.
Expansion in Dynamic Range
The figure below shows the dynamic range characteristics. First the overall frequency response is indicated at a signal fevel where the distortion is made 3%" at't kHz. When the "dbx in" position is selected, there is an increase of about "13 dB" at the 3% point over the "out" position, indicating that the distortion with ,high input levels is greatly
improved.

recording to enable recording with minimal distortion and a wide dynamic range. The linear logarithmic compression and expansion do not make the sound quality undergo change with level mismatching.
Prineiple of basic operation The dbx system works to expand the dynamic range
by
compressing (encoding) the signals and then expanding
(decoding) them. As shown in the figure, the input signal level is
halved during recording onto the tape. During playback the
halved level is doubled to restore the original signal. The figure shows that high signals are greatly expanded (from "+10 dB" to "+20 dB") while low signals are given a low expansion ("-40 dB" to "-80 dB"). This results in a great improvement in the dynamic range and simultaneously in a great reduction in tape hiss.

clear that the noise level is greatly reduced. Because of the great reduction in the noise level and the great expansion in the signal level, the dynamic range at the "dbx in" position is vastly improved, and a dynamic range which is vastly superior to that of a 2-track 38 cmlsec. open-reel tape is yielded.

button.
Now monitor the sound and depress the Play button.
Now before the next program is recorded and this can then
be recorded. This operation creates an unrecorded blank between the material such as commercials.
Fluorescent level meters The unit's level meters employ lluorescent display tubes
to indicate the input and output signal levels in the form of a bar graph. During playback the playback level is indicated, and during recording the recording level is indicated. This unit's meter is designed for "peak" indication. With peak indication, the level meters respond sensitively to rapid bursts of sound such as that from percussion instruments and so it is possible to record up to near the tape's saturation level with very little distrotion and a good signalto-noise ratio. Furthermore, the unit is provided with an auto reset peak hold f unction. ln order to facilitate recording lvel readout, the peak level-apart from the illumination of the meters-can be held on the meter for about 2 seconds. During this time the peak level can easily be read
out. Based on a reference of "0 dB", the unit's fluorescent display meters have markings in two colors lor easy instantaneous readout.
. Timer playback operations cannot be performed il the
noise reduction selector switch is set to the "disc"
position.
ERASING (Refer to fig. 14.) Use the "CrOz" position for erasing normal tapes, ferrichrome tapes and chrome tapes.
Use the
"Metal" position to erase "Metal tape"'
Remote conlrol
The unit incorporateS an lO-based electronic control operation system and so it can be operated remotely using the remote control unit (RP-9645) or the wireless remote control
unit (SH-R808).
Recording with Dolby NR
This unit includes the Dolby noise-reduction system, which reduces tape noise to a remarkable degree. Brielly, the system works as follows: At low sound levels (where tape noise is most noticeable), the highJrequency portion of the sound is recorded at a higher level. Tape noise is not amplified. During playback, the level ot only that portion ol the signal which was increased at the time of the recording, as well as tape noise, rs reduced by a like amount. This causes the
signal to be heard at a normal level, and the tape noise to be reduced significantly.
Monitoring
To listen to the recording as it is being made, simply con-
nect stereo headphones (8o-125o) to the Headphones jack. You may also listen to the program as it is being recorded if your receiver or amplitier is equipped with a
