Before connecting the deck to your amplifier, please review your
amplifier's instruction manual. Use the white plugs for the left
channel and red plugs for the right channel.
•Tape Dubbing
Many stereo amplifiers and receivers have tape dubbing circuitry
so that tape duplication can be performed between two or more
tape decks. Review your amplifier's instruction manual for a full
explanation of this mode of operation.
•Connecting Headphones
To listen through headphones, plug your headphones into the
PHONES jack.
• Installation Precautions
If the deck is placed near an amplifier, TV or tuner, noise (induced

CASSETTE TAPES
• Handling Precautions
• C-120 Cassettes
C-120 cassette tapes are not recommended as they use a very thin tape base which
may become tangled around the capstan or pinch roller.
• Tape Slack Before putting a tape into the deck, take up any slack with a pencil or
your finger tip. This precaution prevents the tape from becoming entangled around
the capstan or pinch roller.
• Storage Precautions
• Do not store cassette tapes in a place where they will be subject to:
• Extremely high temperature or excessive moisture
• Excessive dust
• Direct sunlight
• Magnetic fields (near TV sets or speakers)
• To eliminate tape slack, store your cassettes in cassette cases with hub stops
• Accidental Erasure Prevention
• All cassettes have erasure prevention tabs for each side. To protect valuable
recordings from accidental or inadvertent erasure, remove the tab for the appropriate
side with a screwdriver or another tool.
• To record on a tape whose erasure prevention tabs have been removed, cover the
tab holes with adhesive tape.

•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 button simultaneously with the Fast Forward button when the tape is
traveling in the forward direction. Press the PLAY button simultaneously with the
Rewind button when the tape is traveling in the reverse direction.
The deck will skip the rest of the current selection and automatically resume play from
the beginning of the next selection.
2. To repeat playback from the beginning of the current selection:
Press the PLAY button simultaneously with the Rewind button when the tape is traveling
in the forward direction. Press the PLAY button simultaneously with the Fast Forward
button when the tape is traveling in the reverse direction.
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:
• 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.
• REV close the beginning of the program or CUE close to the ending.

• Relay play will play decks A and B in succession for 5 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 5 cycles
will always be at the opposite side of the tape in deck B.
NOTE: If both decks A and B are set to the play or record modes while in the relay mode,
the relay mode is cancelled and the RELAY indicator turns off. To set the relay
mode again, first set both decks A and B to the stop mode.
The RELAY indicator turns back on.
• TWIN OUTPUT
With the DN-770R, it is possible to play tapes simultaneously on decks A and B and
output their signals at the same time.
When both decks A and B are played, the signals for deck A are output from the deck A
line out jacks, and the signals from deck B are output from the deck A/B line out jacks.
• The deck A line out jacks are exclusively for the deck A signals.
• The deck A/B line out jacks are for both the deck A and deck B signals.
• Use the deck A/B line output jacks when connecting one of the sets of
line outputs to a receiver or amplifier.

• 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.

Reverse mode Operation
Dubbing is performed only for one side.
The decks stop when either deck A or B
reaches the end of the tape.
The tape direction is reversed on each
deck when they reach the end of the tape.
(This is convenient for dubbing to a tape
with a different length.)
RELAY During dubbing of the side facing you, the
deck that first reaches the end of the tape
will stand by until the other deck reaches the
end of the tape, then both decks will reverse
the tape direction together.
(Depending on the manufacturer, the length of
tapes having the same recording time may differ
somewhat. Setting this mode permits the arrangement
of the beginning portion of the opposite
side of the tape.)



To begin normal speed dubbing, press the DUBBING SPEED NORMAL button. The DUB
indicator will light at this time.
To high speed dubbing, press the DUBBING SPEED HIGH button. The HIGH indicator
will light at this time.


 To stop dubbing, press the stop of deck A or deck B.
• When deck A is in the playback mode and deck B is in the stop condition, setting deck B
to the recording pause mode will engage the normal speed dubbing pause mode.
Dubbing is then started by pressing the PLAY button.
• When dubbing, the recording level and the Dolby NR coding will be the same as those
of the playback tape, regardless of the positions of the INPUT LEVEL control and the
DOLBY NR button.
• When listening to the playback sound during normal speed dubbing, set the DOLBY NR
button to match the Dolby NR system with which the playback tape was recorded. This
will assure correct sound reproduction, but does not affect the recording.
• The playback sound cannot be heard during high speed dubbing.
Operation using the REC/REC MUTE (•) and REC PAUSE (II) buttons of deck B is
permitted during normal speed dubbing.
• Buttons other than the stop button cannot be used during high speed dubbing.

1) Operation of the Deck A/B Selector
(1) Press the RESET button to reset the counter to "0000".
(2) By using the PLAY, FF, or REW functions, the reading of the
counter will change to indicate index position.
• During recording and playback operations, the counter is useful for noting the
location of existing programs or positions where recording is to be started.
• The reading of this counter does not correspond with that of any other deck.
(3) Deck A and Deck B have the memory of their own counter. Operate COUNTER A/B
to change Deck A or B to display its counter.
(4) The level meter and Dolby setting display also switch with the
Deck A/B selector.
2) MEMORY STOP Operation
(1) During recording or playback, the Memory Stop feature can be used to locate a
particular point on the tape. Press the COUNTER MEMO button at the desired
point.
(2) The MEMO indicator lights.
(3) When the Rewind (<<) is pressed during forward tape travel (►), or the Fast
Forward (>>) button is pressed during reverse tape travel (◄), the tape is
rapidly rewound (or advanced) until the counter indication of "0000" is reached.
• The Memory Stop feature will rewind or forward the tape to within -5 counts in
the forward (►) direction (from "0000" to "-0005") and to within +5 counts in
the reverse (◄) direction (from "0000" to "0005"). After this, several seconds
are required for corrective operations.
• The Memory Stop function operates independently in both directions for deck A
and deck B. The MEMO indicator will switch over with the use of the DECK A/B
button.
Caution:
If the memory stop operation is performed after repeated fast
forwarding or rewinding, the tape may not stop at the proper position.
(3) Display Back-up
(1) The COUNTER VALUE, DECK A/B, MEMO DIRECTION and DOLBY NR functions are
protected for approximately one month by a memory back-up.
Once the back-up period is up, the DOLBY NR and MEMO settings are set to off,
the DECK A/B setting is reset to "A" the DIRECTION setting is set to (►), and
the counter is reset to "0000".
DECK A / B SELECT AND MEMORY STOP

DOLBY B AND C NOISE REDUCTION SYSTEM
• 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.
• Tape background noise consists primarily of high frequency information, which is
particularly annoying during soft passages. 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 recording, no switching operation or adjustment is required.
The system is effective with any type of Normal, Cr02 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 DENON cassette deck.
MAINTENANCE
• 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. Some cleaning cassettes on the market have strong abrasive effects and may scratch
the heads. Always use cotton swabs instead of cleaning cassettes.
2. 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.
14
• 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 Cr02 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 improved 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.
• 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.)
• 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 each head, making sure you do not touch them.
3. Slowly move the demagnetizer away and turn it off when it is at
least 30 cm away from the heads.
