Commentary
This is a stereo cassette deck that pursues the ultimate in cassette using Akai's unique technologies such as Super GX3 head and Quartz Lock 2 Motor DD system.
The Super GX3 head system is mounted on the head part.
It is a REC/PB combination type that uses High and High μ ferrite material and separate recording head (4 μ gap) and reproducing head (1 μ gap). In addition to excellent characteristics, it also has excellent secondary characteristics such as abrasion resistance, little noise, and dust resistance. It brings out the performance of various tapes including metal tapes.
The most reliable 2-motor system is used for the drive system.
Especially for the capstan drive, a high-grade original brushless quartz-lock DD motor is used. Strong torque and excellent rotational accuracy are realized by a three phase full-wave drive system with Hall element position detection and FG servo + quartz-lock circuit with high accuracy and quick response.
In addition, in order to stabilize high rotational accuracy, it is equipped with a quartz lock, which is phase control by crystal oscillation, and it is combined with a direct drive mechanism to maintain high accuracy.
The recording amplifier uses a DC amplifier to minimize distortion during recording, and the playback amplifier uses a dual FET.
By using computer control with two microcomputers, performance degradation due to wear is reduced by reducing noise and mechanical switching mechanism in operation timing and start-up during recording, and by improving various mechanisms such as auto-tuning, excellent recording and playback are realized.
Equipped with an auto-tuning mechanism that has been developed to extract 100% of the characteristics of various tapes and to record and reproduce them under optimum conditions.
A microcomputer mounted on the deck analyzes the characteristics of each tape and commands the deck for the optimum bias equalizer and recording sensitivity. In particular, the auto-tuning mechanism of the GX-F95 employs an independent double tuning method in which the equalizer and recording sensitivity are tuned twice for each side (bias is applied twice for each side simultaneously).
When tuning, a method is used to avoid the beginning of winding where the tape characteristics are unstable by automatically fast-forwarding.
Equipped with an automatic tape position selector mechanism, the deck detects the type of tape set at the same time as the tape set switches the tape position.
Equipped with an electronic digital tape counter.
It is equipped with a recording cancellation mechanism. If you make a mistake in timing by CM, etc., it will automatically return to the head of the recording section and enter the standby state.
Each operation state such as Play/FF/RWD/REC/PAUSE can be checked with the self-illuminated button.
The function indicator displays the operation of each mechanism in a centralized manner.
Equipped with 2-color 24-segment FL bar meter with peak hold.
The peak hold time is approximately one second, and a VU / peak switching switch is installed.
Two types of cassette lids are included. In addition to the aluminum type, there is also an acrylic type that shows the tape running.
Equipped with recording mute mechanism, microphone / line mixing mechanism, Dolby NR with MPX filter switch, etc.
Equipped with remote control terminal and timer mechanism.
There were 2 types, GX-F95 of walkers or rollators for the elderly type and GX-F95BL of black type.
