SYNCRO REVERSE DUBBING
During dubbing of the side facing you, the deck that first reaches the
end if the tape will standby until the other deck reaches the end of the
tape, direction together.

recording time may differ somewhat. Setting this mode permits the
arrangement of the begining portion of the opposite side of the tape.)
1. Press the POWER switch
q to the ON (

recording is to be started.
¼ The reading of this counter does not correspond with that of any
other deck.
í The Dolby noise reduction system substantially reduces the tape
background noise (hiss) inherent in the cassette medium.
í 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.
í 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.

the instruction manual of your CD player.)
¼ When the MARANTZ CD-57, CD-67 or CD6000 CD player is used,
be sure to set the REV. MODE switch to "=". (This causes both
