Relay play will play decks A and B in succession for 6
cycles, upon which playback stops. When playback starts
from deck B, when switching to deck A, the first deck A
playback cycle will be counted as the second cycle. The
completion of 6 cycles will always be at the end of the tape
in deck B.
H MUSIC SEARCH SYSTEM
The music search system detects blank sections (lasting for at
least 4 seconds) between selections in order to locate the
beginning of selections in the forward or reverse direction.
1. To advance from the current selection to the beginning of the
next selection (CUE):
Press the PLAY (Pp) button simultaneously with the Fast
Forward { Pp ) button.
The deck will skip the rest of the current selection and
automatically resume play from the beginning of the next
selection.
To repeat playback from the beginning of the current selection
(REVIEW):
Press the PLAY (Pp) button simultaneously with the Rewind
( 44 ) button.
The deck will rewind the tape to the beginning of the current
selection and automatically resume play from that point.
This is very convenient for repeating playback of the current
selection.
Notes on Music Search Operation:
The search functions operates by detecting comparatively long,
blank sections approximately 4 to 5 seconds long, in between
recorded selections. Therefore, the system may not operate
normally in the following cases:
e Recordings with discontinuous speech or conversation.
® Recordings with long periods of pianissimo (softly played
music).
Recordings with long silences.
Blank sections with a high level of noise.
Blank sections shorter than 4 seconds.
If noise-emitting appliances, such as electric razors, drills,
refrigerators, etc., are operated nearby.

The best way to avoid accidental erasure is to break off the two
erasure prevention tabs on the cassette housing.
M PROPER RECORDING LEVEL
A too high recording level can saturate the tape and cause
distortion. On the other hand, if the recording level is set too
low, soft passages will be marked by residual noise. A proper
recording level is the single most important factor for making
well balanced recordings.
Guideline for maximum recording level
TYPE | (Normal) 0 dB level on peaks
TYPE Il (CrO,) +3 dB level on peaks
TYPE IV (Metal) +3 dB level on peaks
Note: The optimum recording level differs depending on the
program source and the type of tape used.
IM RECORDING BIAS ADJUSTMENT
—
For best recording results, monitoring during recording and
comparing different recordings using your own judgement are
essential.
The DRW-650 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 & REC PAUSE
. To record a 5-second blank section during recording:
Press the REC/REC MUTE (®) button. A 5-second blank will be
recorded and the deck will enter the recording standby mode.
2. To record a 5-second blank section during the recording
standby mode:
Press the REC/REC MUTE (®) button from the recording
standby mode. A 5 second blank will be recorded and the deck
will enter the recording standby mode again.
ENGLISH
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 be 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.

lB The Dolby noise reduction system substantially reduces the
tape background noise (hiss) inherent in the cassette medium.
Dolby B NR is most widely in use. However Dolby C NR is a
much more recent development and represents significant
improvements over Dolby B NR.
H Tape background noise consists primarily of high frequency
information, which is particularly annoying during soft pas-
sages. The Dolby NR system increases the level of low volume
mid- and high-frequency signals 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, 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 record-
ing, no switching operation or adjustment is required. The system
is effective with any type of Normal, CrO, and Metal tape.
The Dolby HX-Pro headroom extension system functions during
recording to raise 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 the new DRW-650 cassette deck.
H 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 20 dB, compared to 10 dB with Dolby B NR. In addition,
Dolby C NR uses an anti-saturation network and spectral
skewing circuitry for a significant improvement 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 improved to
very close of that offered by Metal tape.
(2) The dynamics in the treble range are improved significantly.
(3) Since no decoding is necessary during playback, the im-
proved sound can be enjoyed on any type of tape deck,
including portable players and car audio systems.
(4) The system functions whether the Dolby B/C NR system is
engaged or not.
ENGLISH
MAINTENANCE
№ Removing the cassette compartment cover
It will be more convenient if the cassette compartment cover is
removed during the cleaning of the pinchroller and heads, or
during demagnetizing of heads.
Follow these procedures:
1. Press the EJECT button to open the cassette compartment.
2. Hold only the cover of the cassette compartment and pull it
up. The compartment cover is removed from the front.
When attaching the cassette compartment cover, reverse the
above procedure.
№ Head Cleaning
After long usage, tape coating or dust may adhere to the
heads, causing deterioration of sound. Therefore, the parts
depicted in the illustration should be cleaned regularly. Use a
cotton swab moistened with a tape head cleaning solution
(such as alcohol).
Note:
1.
12
Some cleaning cassettes on the market have strong abrasive
effects and may scratch the heads. Always use cotton swabs
instead of cleaning cassettes.
Since the use of metal tape is apt to collect more dust on the
heads, the heads should be cleaned more often to enjoy the
best possible sound.
IM Cleaning the Pinch Rollers and Capstans
If the pinch rollers or capstans accumulate dust, tape transport
may become unstable, as a result from slippage, during
recording or playback. The tape can also be damaged if it gets
entangled in the capstan.
Clean these parts with a cotton swab or a soft cloth moistened
with a tape head cleaning solution (such as alcohol).
Demagnetizing the Heads
The heads will become magnetized after long usage or if
strongly magnetized objects are brought near them. The result
is a generation of noise, loss of the high frequency range, and
in extreme cases erasure of treble components on pre-
recorded tapes in combination with added noise.
Thus, the heads should be demagnetized at regular intervals.
(Head demagnetizers are separately available from your
dealer.)
Ш How to Demagnetize the Tape Heads
1. Turn off the power.
2. Turn on the demagnetizer while it is at least 30 cm away
from the heads. Bring the demagnetizer near the heads and
slowly move it in small circles four or five times in front of
