AKAI GX-630D Manufacturer's Description

Hi-Fi Performance

Stereo record and playback. GX Head, AC Servo Motor, Direct Capstan Drive System Wow and Flutter reduced to 0.06%, Distortion less than 0.5%, S/N Ratio better than 57 dB.

Recording and Playback heads

As is well known, the core of Akai's GX Head is made of crystal ferrite and is mounted and set in glass. The superior magnetic properties of the head material and special processing allowed the formation of a perfectly lineal shallow head gap, an acute head surface angle contour, and focusing of the magnetic field into a sharp oblong radius. This focused field system eliminates undue equalization, minimizes high frequency loss, and achieves a wider dynamic range. Further, sound drop-out is eliminated, head-to-tape contact and signaLto-noise ratio improved, and the hardness of the head materials provide dust free and wear free characteristics for longer lasting performance. The GX-630D exhibits a clear frequency response range to 25,000 Hz with Akai LN-15G-7 Tape.

Three motor drive system

This model employs a 3 motor drive system with a new CFG (center pole generated) AC Servo Motor for direct capstan drive. The quality of this outstanding motor plus the elimination of rubber belts and flywheels results in the realization of a 0.06% Wow and Flutter factor. Two eddy current outer rotor motors complete the drive system for completely stable performance and excellent tone quality. Impedance Roller and Tension Levers also add to tape travel stability.

10-1/2" Reel capacity

A Reel Size Selector and standard accessory 10-1/2" reel hub adapters facilitate the use of 5, 7, or 10-1/2" reels. Further, this model features "quick tension" wherein ideal take-up and back tension is applied to the reels at the beginning of tape start for smooth operation regardless of reel size.

Feather-touch controls

Feather-touch Full Direct Function Change Control for speedy mode change. This feature includes direct function change to recording mode for easy add-on recording. The Automatic Stop/Tension Arm drops at the end of the tape, activating an automatic stop mechanism which completely stops reel movement for operating safety. When Pause Mode is effected, the tape remains in contact with the heads and the pinch roller separates from the capstan only slightly so that when the Pause Lever is released, re-start is fast and smooth. Pause Control is especially convenient for editing tape.

Inputs and Outputs

A built-in mic-line mixing circuit and independent Microphone and Line Input Level Controls facilitate easy sound mixing from separate sources. A Tape/Source Monitor Switch enables comparison of source signals with the recording being made for more professional recording results. Output level control can be adjusted to correspond with amplifier input enabling connection with any amplifier. Jack for remote control of all operating functions as well as absentee recording with optional accessory Remote Control Unit RC-17, a Tape Selector Switch for use of Low Noise or Wide Range Tape, and a convenient lift-up type head cover for easy head block accessibility.


I read the Operator's Manual of this fine audio equipment. The front cover give but one warning important enough to be read before all other warnings. Warning: To prevent fire or shock hazard, do not expose this appliance to rain or moisture. I am correct in my assumption that I cannot play the greatest opera in the rain.
