|GXC-46D:59,000 yen( at the 1972 time?)
The stereo cassette deck carrying GX head, a Dolby system, and an ADR system.
GXC-46D becomes a cassette deck and the cassette tape recorder with which
GXC-46 carried the speaker etc. in GX-46D.
GX head which the Akai was
original and developed is adopted as a head.
This head is using special hard
glass for low noise single crystal ferrite and a carrier at core material, it is
adopting it as a magnetic recording reproducing head, and recording by the
outstanding head touch and the sharp focal field is realized.
A. The D.R
(Automatic Distortion Reduction) system is carried, and with the level of an
incoming signal, a recording equalizer is changed automatically and it is
recording in accordance with the dynamic range of a tape.
Since the recording in a portion with the linearity of a high region sufficient
thereby always is attained and reduction of the record signal by a previous
distortion and demagnetization action etc. is lost, degradation of the
frequency response in high level, distortion, and a beat are stopped.
The Dolby system is carried as a noise reduction
When the case of only compass lower than a fixed level with an
incoming signal when recording on a tape theoretically, and the whole volume are
small and noise is conspicuous, volume is raised automatically and the whole
volume difference is made to compress.
And only the quantity automatically
reinforced at the time of a play is decreased, and noise of quantity returned
also decreases by returning as before.
In order to solve the problem of
the low cassette of the saturation point compared with an open reel, the O.L.S.
(Over-Level Suppressor) circuit is carried. If a switch is switched, even if the
time of making a level excess and a momentarily big input should enter, sound
will not be distorted but will be held down to 2% or less of a distortion.
It is possible to carry the tape changeover switch, to change suitable
bias and the amount of frequency compensation on a tape, and to pull out the
engine performance of a chromium tape.
The direct function change
mechanism is carried, and only by pushing the manual operation button of hope
directly in the state of recording / play / fast forward / rewinding, even if it
does not push a stop button, it goes into the mode chosen automatically.
The hysteresis synchronous motor is carried in the motor.
meter and a triple figure index counter are carried.
