Commentary
A vertical type stereo cassette deck that can be directly viewed just like a open-reel.
As a lower model of GXC-510D, performance is improved by omitting functions.
Single crystal GX head is used for the head.
The core of this head is made of a single crystal, and it is uniform to the inside of the tissue and has excellent electromagnetic characteristics. Moreover, since it is made of a pure crystal core, it is excellent in durability. Since the whole shape and the width and depth of the gap can be designed ideally, it is possible to reduce the compensation amount of the high-frequency range on the recording side by the magnetic field of the focus field. This excellent core is wrapped in ultra-hard glass, and excellent characteristics are obtained.
The drive section uses a hysteresis synchronous motor developed by Akai especially for cassettes. This motor uses a SNCII for the shaft and aluminum alloys for the case. In addition to structural features such as the invention of a damper ring and the adoption of fixed metal, it offers high precision and long life.
Equipped with independent left and right recording level control.
Equipped with a large meter.
Equipped with a tape selector, it supports chrome and low-noise tapes.
