The cassette deck which carries various
functionalities and a noise reduction system in order to correspond to a digital
The automatic-reversing functionality by the infrared photosensor
and a rotary head is carried.
The difference of the reflection factor of the
magnetic-substance fraction of a tapes and a reader fraction is detected, a
rotary head rotates immediately, and an infrared photosensor performs a reverse
A rotary head does not have a tone-quality difference in order to
carry out the Recording play of the both-way bothways with the same head, and
azimuth adjustment is possible for it in bothways.
In the mechanism,
microcomputer +3 only for 2 K bytes motor (it is one motor each the object for
capstans, the object for reels, and for a head migration) was carried, and the
operation which was trustworthy and was stabilized is realized in it.
The large-sized fly wheel was adopted and the smooth rotation has been
The back tension dynamically stabilized by the dynamic
stability tension system of the newly developed tension organization which
employed new-materials Lu Ron is maintained.
In order to banish the
variation in the run performance in the round trip which poses a problem on the
reverse deck, the double dummy head is carried.
Each sides of the rotary
head were equipped with the dummy head, and the tapes run which kept the tapes
location exact and was stabilized is attained.
The audio circuitry has
DC composition made into only two coupling capacitors from the input to the
output, and DC stream composition of a head hardwired connection is raising the
Moreover, logic circuitries, such as an audio system and
each window control, and a power circuit are made to separate, influence is
suppressed, and the tone quality is raised.
Dolbey B/C and dbx are
carried in the noise reduction system.
The synchro recording
functionality is carried and a sound-recording start can be controlled at the
player start of a play equipment by combining with the equipments
(compact-disk-84 etc.) equipped with the synchro recording termination.
The blank search function is carried, the head of the unrecorded
fraction of a recorded tape is found, and from there to about 3-minute after, after play checking, a sound-recording standby (REC/PAUSE) is returned and
carried out to the head of a unrecorded part.
If the quick rewind
functionality is carried and a hoist back-out switch is pushed after a sound
recording, it will return to the location which started the sound recording, and
a play standby (Play/Pause) will be carried out automatically.
unrecorded fraction for 4 seconds is made from one-touch, and the auto REC-Mute
functionality which carries out a sound-recording standby automatically is
The QMS (quick music sensor) functionality in which transfer
song selection of 20 music is possible is carried approximately.
index scan functionality which reproduces the head fraction of each music for 10
seconds at a time is carried.
The memory functionality is carried, a
tapes location is memorized by memory switchpoint operation, and a stop and a
play can be performed in the location.
By pushing a play switchpoint
twice, an one music repeat play is possible.
Independent equipment of
the volume which can control an output output and a headphone output is carried
The large-sized display device consisting mainly of a peek hold
level meter and 4way digital counter is carried.
The Marantz bus system
is carried and a remote control etc. becomes possible by the interconnection
with a balance bus system loading model.
