This device is a convenient system which detects the
non-recorded part of more than 4 seconds between melodies,
cues the next melody while the present melody is being
reproduced or automatically detects the beginning of the
melody now being reproduced and makes it into the repro-
duceable state. ©. e 5
1. For cueing the next melody while the present melody
is being reproduced:
At PLAY mode, depress the PLAY button and the FF
button simultaneously. This device will detect the
interval between melodies with the CUE state on, auto-
matically become the PLAY mode and begin performing
the next melody.
2. For hearing again the melody being reproduced:
At PLAY mode, depress the PLAY button and the REW
button simultaneously. This device will detect the
interval between melodies with the REVIEW state on,
automaticaliy become the PLAY mode, detect the be-
ginning of the melody now being performed and pla
it from the first again. |
PROPER RECORDING LEVEL
Note about MUSIC SEARCH action:
MUSIC SEARCH is a function which operates by detecting
a comparatively ¡long non-recorded part on the tape. There-
fore, MUSIC SEARCH may not operate normaliy in the
following cases.
e Sound on the tape is interrupted by speech or conversa-
tion.
eLong periods of pianissimo (softly played music) or
non-recorded intervals occur on the tape.
e The tape has picked up noise in a non-recorded interval.
e Non-recorded intervals on the tape are less than 4 seconds
in length.
e Noise-emitting electrical appliances are in operation
nearby. i.e.; Electric razors, drills, refrigerators, etc.
A too high recording level can saturate the tape and cause
distortion. On the other hand, it the recording level is set
too low, soft passages will be marked by residual noise.
À proper recording level is the single most important factor
for making well balanced recordings.
Guideline for maximum recording level
TYPE I (Normal)
+1 dB level on peaks
TYPE I (CrQy) +3 dB level on peaks
TYPE NV (Metal) +5 dB level on peaks
Note: Theoptimumrecording level differs depending on the
program source and the type of tape used.
RECORDING BIAS ADJUSTMENT
For best recording results, monitoring during recording and
comparing different recordings using your own judgement
are essential.
The DRS-810 is equipped with a BIAS FINE control to assist
you in setting the proper bias for different types and brands
of tape. At the center stop-click position, the deck is set
to the reference bias level for Normal, CrO; and Metal tape.
If the resulting recording in this position has too much or
too little high frequency content, adjusting the BIAS FINE
control can be useful to achieve better results.
BIAS FINE
REC/REC MUTE AND PAUSE BUTTON
Meter reading differences between Left and Right
channels
The left and right channel readings of the Peak Level Meter
can differ due to variations in the input signal levels. In such
cases, use the BALANCE control to adjust the channel input
balance until identical meter readings are obtained for both
channels.
If the high frequencies {treble sounds) are to the boosted,
turn the BIAS FINE control counter-clockwise to decrease
the bias current. Turn the control clockwise to increase bias
current.
By the use of this control, you can record tapes with a
frequency response that will perfectly match your listening
taste. |

The linear tape counter and remaining tape counter of this

When using a tape of a special size, select the TAPE SIZE
which is nearest to that of the used tape. (The tape counter
error will then be smaller.)
Note also that the linear tape counter and remaining tape
counter do not work as accurately as a clock. Small devi-
ations may occur because the thickness of the tape differs
depending on the type (position, tape length) of the used
cassette. Slight errors may also be caused by the difference
between cassettes with a large hub and cassettes with a
small hub.

DOLBY B & C NOISE REDUCTION SYSTEM
Mm The Dolby noise reduction system substantially reduces
the tape background noise (hiss) inherent in the cassette
medium. Dotby B NR is most widely in use. However,
Dolby C NR is a much more recent development and
represents a significantly improvements over Dolby B NR.
Ш Tape background noise consists primarily of high frequency
information which is particularly annoying during soft
passages. The Dolby NR system increase the level of
tow volume mid and high frequency signal during recording
and reduces the level of these signals by an identical
amount during playback. As a result, the playback signal
is identical to the original source signal, but the level
of background noise generated by the tape is greatly
reduced.
DOLBY HX-PRO HEADROOM EXTENSION SYSTEM
This deck is equipped with the DOLBY HX-PRO headroom
extension system. Since the system functions automatically
during recording, no switching operation or adjustment is
required. The system is effective with any type of Normal,
Cr0, or Metal tapes.
The Dolby HX-PRO headroom extention system functions
during recording to lift up the saturation level in the treble
range. Therefore, most of the treble range components
distorted or lost during recording on conventional cassette
decks are more faithfully recorded on tne new DRS-810
cassette deck.
MN The operating principle of Dolby C NR is similar to that
of Dolby B NR except for the encoding/decoding response
curves. The noise reduction effect obtained with Dolby
C NR is up to 20dB, compared to 10dB with Dolby B NR.
In addition, Dolby C NR uses an anti-saturation network
and spectral skewing circuitry, for a significant improve-
ment in the dynamic range of the mid- to high-frequencies.
Features of the DOLBY HX-PRO headroom extension
system
(1) Performance of Normal and CrO, tapes can be up-
graded closer to that of Metal tapes.
(2) The dynamic range in the treble is improved signifi-
cantiy.
(3) Since no decoding in playback is necessary, the
improvement can be obviously heard on any hi-fi
playback system including portable components and
car systems.
(4) The system functions whether the Dolby B/C NR is
engaged or not.

in the playback condition, hook a stick type spring balance to the
bracket on the central axis of the pinch roller. After pulling the
pinch roller away from the capstan shaft, let the pinch roller con-
tact the capstan shaft as it is and verify that the readings on the
stick type spring balance are 250 to 350 g on the right side and
70 to 150 g on the left when the pinch roller starts turning. If the
readings exceed the standard values, replace spring 26) or

(1) Set THG-801 (ig board) on the mechanical unit and perform
the adjustment by turning the special height adjustment
screw so the 3.8 mm part on THG-801 (lig shaft)
can move without touching the tape guide on the recording/
playback head
(2) Turn the azimuth adjusting screw so that the
recording/playback head does not tilt whileadjusting the
height, and make a rough visual adjustment.
4-2 Adjustment of tilt angle
(1) Set THG-801 (jig board) in the mechanical unit and place
THG-801 (jig shaft) on the recording head to inspect the
gap between the jig board. if the jig shaft is tilted forward,
the tilt screw is too tight. Loosen it slightly and
adjust the tilt screw (745 until the jig stick is parallel to
the jig board and the gap is completely eliminated.
(2) Readjusting the tilt may cause the height adjustment to slip.
After adjusting the tilt, be sure to verify the height.
If the height is misaligned, turn the special height adjustment
screw “and the tilt screw as to the same angle
to shift the recording/playback head so it is parallel to the jig
board for height readjustment. After the adjustment is
completed, tighten the lock nuts.
