The cassette deck which employed the plunger mechanism of a system and a 2 motor
IC logic circuit corresponding to a metal.
The plunger mechanism by IC and 2
motor composition is employed, and the operativity of a click touch is realized.
The dual motor drive system is carried in the mechanism part.
is 2 motor systems which roll round with a capstan and drive a reel by a motor
for exclusive use, respectively, works with a margin compared with 1 motor
system, and is improving accuracy and durability.
DX head developed on
the assumption that metal tape use is adopted as a head.
This head has
realized the guard part by Sendust, electromagnetism conversion nature which
consists of the magnetic pole of the special structure which laminated the core, and was excellent in the hard complex material, and antiwear quality. Moreover,
there is allowance also in the maximum magnetic flux density which is a point in
the case of using a metal tape, and it is not saturated with the big bias
current which a metal tape requires.
Moreover, the linearity of recording amplifier has gained the data exceeding a metal tape, and also supports the dynamic range which a metal tape has.
Guide-type VU meter and the peak
level indicator of three-point LED are carried.
A level setup which the
indicator showed the maximum level value of the peak according to LH, CrO2, and
metal tape to the scale of +4, +6, and +10, and was united with the tape is
The tape selector is carried, and if a knob is set to the
position currently displayed according to LH, CrO2, and a metal, a bias value and an equalizer value will be set simultaneously.
If the auto-repeat
mechanism is carried and a switch is set to the repeat side, after a tape is
completed, it will be rolled back automatically and a tape will be played
Moreover, if a tape is completed also from a recording
state, in order to work, it shifts to playback immediately.
standby mechanism is carried.
REC Mute and the Dolby system interlocked with the MPX filter are carried.
By connecting an optional remote
control unit, it can be operated also from the distant place.
