AKAI GX-650D - GX Head and Dual Capstan

AKAI GX-650D

The AKAI GX-650D was introduced in 1976. It's a 3 Head, 3 Motor stereo tape deck featuring an efficient Closed Loop Double Capstan AC Servo Motor system. The recording and playback heads of this model are AKAI's famous GX (glass and crystal ferrite) heads. The special construction of this head eliminates sound drop-out, improves head sensitivity, and minimizes high range loss for a more dynamic range with vastly improved high range frequency characteristics. Also signal-to-noise ratio is improved and distortion minimized. The GX-650D operates on 15, 7-1/2, and 3-3/4 ips tape speed. AKAI's exclusive CPG (center pole generated) system inner-rotor AC Servo Motor is employed in this model for double capstan drive. With this system, the voltage supplied to the stator winding is pulse detected and precisely controlled for stabilized motor revolutions and constant tape speed. Two oil circulating mechanisms with cellulose fibers are installed within the interior of the motor. This oil-circulating system assures smooth and stable shaft revolutions. Two 6-pole eddy current anti-vibration outer rotor reel drive motors complete the perfect drive system of this model. Technical data: Track system - 4 track 2 channel stereo/mono system, Reel capacity up to 10-1/2", Wow/Flutter less than 0.04% RMS at 15 ips, Frequency response 30 to 30,000 Hz +/- 3 dB at 15 ips, Signal-to-noise ratio better than 58 dB, Dimensions 524 (H) x 442 (W) x 258 (D) mm, Weight 26.2 kg.
