4. Press the SYNC REV button i to set the SYNC REV Mode.
The SYNC REV Indicator will light up.
To release SYNC REV mode, press the SYNC REV button again.
When direction of Deck A and Deck B is only Forward (
), the
SYNC REV mode can be set.
5. To being normal speed dubbing, press the DUBBING SPEED
NORMAL button r. The NORM DUB indicator will light at this
time.
To high speed dubbing, press the DUBBING SPEED HIGH button
r.
The HIGH DUB indicator will light at this time.
6. To stop dubbing, press the STOP ( ) button t of deck A or
deck B.
¼ When dubbing, the recording level and the Dolby NR
recording will be the same as those of the playback tape,
regardless of the positions of the REC LEVEL control and the
DOLBY NR switch.
¼ When listening to the playback sound during normal speed
dubbing, the DOLBY NR switch remains off even if it is
pressed.
¼ Operation using the REC MUTE u and PAUSE ( ) y
buttons of deck B is permitted during normal speed dubbing.
¼ The following operation is available only when a MARANTZ CD
player with the synchro recording capability is connected to the
cassette deck.
¼ To use synchro recording, connect the remote control cord
terminals on the CD player and cassette deck.
1. Load a cassette tape in Deck B.
2. If Dolby NR recording is required, select type B or C.
3. Press the RECORD/o button to put the cassette deck in record-
pause mode.
4. Adjust the recording level with the REC LEVEL control.
5. Start edit playback of the CD player. (The operation procedure
may be variable between CD players with edit function. Refer to
the instruction manual of your CD player.)
¼ When the MARANTZ PMD371 CD changer is used, it is possible to
set the REV. MODE switch to “ ”. (This enables to record
both A and B sides continuously.)
¼ When other MARANTZ CD player than the above mentioned
models is used, set the REV. MODE switch to “ ”. (This
causes only tape side A or B to be recorded.)
SYNCHRO RECORDING PROCEDURE (Deck B)
1) Operation of the Tape Counter
(1) Press the COUNTER RESET button to reset the counter to
“ ”.
(2) By using the PLAY, FF, or REW functions, the reading of the
counter will change to indicate index position.
¼ During recording and playback operations, the counter is useful
for noting the location of existing programs or positions where
recording is to be started.
¼ The reading of this counter does not correspond with that of any
other deck.
¼ The Dolby noise reduction system substantially reduces the tape
background noise (hiss) inherent in the cassette medium.
¼ 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.
¼ 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.

DOLBY B AND C NOISE REDUCTION SYSTEM
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, High and Metal tape.
The Dolby HX PRO headroom extension system functions during
recording to raise the saturation level in the high frequency range.
Therefore, most of the high frequency range distorted or lost during
recording on conventional cassette decks are more faithfully
recorded on the new MARANTZ cassette deck. Features of the Dolby HX PRO Headroom Extension System
(1) Performance of Normal and High Position tapes can be improved
to very close of that offered by Metal tape.
(2) The dynamics in the high frequency 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.
