A&D GX-R3500

Commentary

A quick reverse deck designed to improve the sound quality of the reverse deck.

Bi-directional symmetrical precision (BSP) mechanism is used for the mechanism.
In the BSP mechanism, the tape transport is made almost symmetrical so that the characteristics of the reciprocating tape travel are made uniform, and the difference in sound quality due to the travel difference between forward and reverse directions is reduced.

In order to reduce the sound blank generated during quick reverse, an infrared sensor is used to detect the joint between the magnetic band of the tape and the leader tape and invert the tape. This realizes playback with almost no sound break.

An intelligent CRLP (Computer Rec-Level Processing) system is installed as an automatic recording level setting mechanism.
By combining a microcomputer with an electric volume, this system automatically sets the recording level while responding to all types of tapes, types of sources, noise reduction, and so on.

The Twin Field Super GX head is used for the recording and reproducing head.
The GX is an acronym for Glass & X' tal. The core is made of ferrite with high hardness and excellent magnetic characteristics, and the surrounding head gap is filled with glass with the same hardness as ferrite. This realizes excellent wear resistance and high-frequency characteristics. Compared with amorphous materials, the GX has excellent head life and high-frequency characteristics.
In addition, the Twin Field Super GX head achieves the same performance as the 3-head by providing separate recording and playback gaps in the head housing, and the use of LC-OFC for the head winding reduces the deterioration of sound quality.

The cassette half is equipped with I / V / O (Improved Vibration Off) cassette stabilizer.
This stabilizer uses Sorbocein to greatly reduce the contamination of medium and low frequency sounds caused by the chirping of the cassette half. In addition, the conventional type has been further improved to cope with various cassette half, and the adhesion is improved by processing the surface into a convex shape.

Equipped with a bias adjustment mechanism, the bias amount can be adjusted according to the tape.

High-tune DC amplifier configuration is used for the amplifier section.

Equipped with CD/DAT direct terminal.

Equipped with Dolby HX-PRO.
In addition, Dolby B/C NR is installed as a noise reduction system.

Equipped with an auto tape selector.

It is equipped with IPSS which can select up to 16 songs in front and back.

Equipped with MPX filter.

Wireless remote control is included.
