The stereo cassette deck which supplied the original technology which Akais,
such as super GX3 head and a Quartz lock 2 motor DD system, have, and
investigated the extreme of the cassette.
The super GX3 head system is
carried in the head part.
It is the REC/PB combination type which used High
Bs and High mu ferrite material, and made the recording head (4micro gap) and
the playback head (1micro gap) become independent,In addition to the merit of
many characteristics, it has the engine performance excellent also in the
secondary characteristics, such as little of antiwear quality or a noise, and
the difficulty of being attached of garbage, and the engine performance of
various tapes including a metal tape is pulled out.
Most reliable 2
motor system is adopted as a drive system.
Especially, the high-grade
original brushless Quartz lock DD motor is used for a capstan drive, with the
three-phase-full-wave drive system by Hall device position detection, it is
highly precise and the early FG servo + Quartz lock circuit of a response has
realized the strong torque and outstanding rotation accuracy.
order to stabilize high rotation accuracy more, the Quartz lock which is the
phase control by crystal oscillation is carried, and high accuracy is conjointly
maintained with the mechanism of a direct-drive system.
amplifier is performing direct-current-ization in order to suppress the
distortion at the time of recording to the minimum. Moreover, an improvement,
such as adopting dual FET, is aimed at in reproduction amplifier.
computer control by two sets of microcomputers is adopted, and the improvement
of reduction of the performance degradation by wear etc. is realized because the
noise in the timing of operation and the standup at the time of recording and a
mechanical change mechanism decrease.
Furthermore, many mechanisms including
auto tuning have been improved and the outstanding Recording play is realized.
The auto tuning mechanism developed so that the characteristic might be
pulled out 100% and a recording play could be carried out on the optimal
conditions to various tapes is carried.
The microcomputer carried in the
deck analyzes each tape characteristic, and orders a deck optimal bias equalizer
and recording-play sensitivity. The right-and-left independent double tuning
system which performs tuning of an equalizer and recording-play sensitivity to
right-and-left independence 2 times respectively (right and left bias is
simultaneous 2 times) is used especially for the auto tuning mechanism of
When tuned up, the method of fast forwarding automatically a cut
water portion with the unstable tape characteristic, and avoiding it is taken.
The auto tape position selector mechanism is carried, and simultaneously
with a tape set, a deck detects the kind and switches a tape position
The electronic digital tape counter is carried.
When the recording cancellation mechanism is carried and timing is
mistaken by CM etc., it will return to the head of a recording part
automatically, and will be in a standby state.
Each operating state, such as Play/FF/RWD/REC/PAUSE, can check with a illuminaned
Moreover, the operation of each mechanism is indicated by intensive with a
2 color 24 segment FL bar meter with a peak hold is
A peak hold is about 1 second, and also carries the changeover
switch of VU/peak.
Two kinds are attached and a cassette lid has an
acrylics type which appears besides an aluminum type as for a tape run.
Dolby NR with a recording mute mechanism, a microphone / line mixing
mechanism, and a MPX filter switch etc. is carried.
The remote control
terminal and the timer mechanism are carried.
There were two kinds of
GX-F95 BL GX-F95 of a silver color and black type.
