Akai GX-210D reel-to-reel tape deck

Three Motor Automatic Reverse Stereo Tape Deck

GX-210D features 3-motor drive mechanism includes self-lubricating Hysteresis Synchronous Motor

To match the lasting performance of the GX Head, the GX-210D is equipped with Akai's unique self-lubricating capstan motor. The installation of two oil circulating mechanisms with cellulose fibres within the interior of the motor provides long lasting, trouble-free operation. Oil circulating speed is adjusted naturally according to motor revolutions and temperature, and because shaft rotation is always smooth and stable, various mechanical troubles resulting from oil circulation suspension do not occur. Further, these unique cellulose fibres also function as filters to keep the oil clean during the circulating process, adding to the motor's epoch-making longevity. Two highly efficient outer-rotor motors for supply and take-up reel drive assure consistent and smooth tape travel and ideal starting torque.

Akai 1730D-SS reel-to-reel

4-channel / 2-channel Stereo Tape Deck

An entirely new world of sound has been created by Akai's electronics engineers who have developed a new and sophisticated line of 4-channel surround stereo equipment. Included in this line are the exciting 1730D-SS 4-channel/2-channel Stereo Tape Deck and 1730-SS 4-Channel/2-Channel Stereo Tape recorder.

With either system, you're completely surrounded in sound with four speakers, left and right in front, and left and right in the rear. This system gives you a real "sense of presence", the feeling of being exactly in the middle of a live performance. Both models are designed to be used for not only 4-channel stereo but also 2-channel stereo as well.

The 1730D-SS is perfectly matched with Akai's exclusive AA-6100 amplifier. this amplifier has 80 W music power for dynamic 4-channel stereo sound and accommodates both 4-channel and 2-channel stereo operation.

 

Akai's dependable 2-lever system complements the high grade parts and robust construction of this rugged 4-channel/2-channel stereo model

It is regular practice to employ mechanical control in one-motor tape decks.  Akai has long since employed this 2-lever system in our one-motor decks. When compared to an ordinary 1-lever system, because the Play/Rec and F.Fwd/Rew Levers are independent, the movable range of the levers are shorter, and operation is lighter. Also, because the F. Fwd/Rew Lever is separate, mis-operation is minimized. Further, because of the mechanical structure of this control system, other parts are not unfavourably influenced and mechanism endurance is extended. Rectangular shaped Control Panel with proportionately balanced controls.

Akai GX-280D-SS tape deck

4-Head 3-Motor Automatic Reverse Surround Stereo Tape Deck

Akai's GX Head 4-Channel Surround Stereo system eliminates the inability to pick up and reproduce true concert hall sound. Every pitch of sound and reverberation effect is reproduced with all of the exciting "sense of presence" experienced when attending a live concert. Akai's surround stereo supplements conventional stereo's two front speakers with two additional rear speakers to front the "2-2 system". The listener is surrounded by two sets of speakers (left & right front and left & right rear). This arrangement does not mean, however, that simply adding two speakers to a 2-channel stereo system is all that is necessary for 4-channel stereo playback. Four separate recordings are made using four individual channels (four tracks in one direction) of the magnetic recording tape. This 4-channel stereo tape feeds into four pre and main amplifiers to activate a 4-speaker system. Thus, at playback time, sounds from separate channels are emitted from each speaker providing the listener with a feeling that he is listening to concert hall sound from the best seat in the auditorium. Model GX-280D-SS is a compatible 4-channel/2-channel stereo model. For 2-channel stereo operation, only the front channels are utilized. For exciting 4-channel surround stereo, a 4-channel stereo external amplifier or two 2-channel stereo amplifiers can be used to activate a 4-speaker system.

 

GX (Glass & Crystal Ferrite) Head

Akai has equipped this model with its new and amazing Glass & Crystal Ferrite Recording and Playback heads to bring you unequalled open reel high fidelity sound. With the Glass & Crystal Ferrite head, superbly wider frequencies with clear highs can be recorded in all their true fidelity with low noise tape. In other words, with the GX head, a high dynamic range and excellent Signal-to-Noise Ratio are achieved. The secret of this quality head is made of single crystal ferrite and is mounted and set in glass. The superior high range characteristics are contributable to thw structure of the head gap which focused the magnetic field into a sharp oblong radius. This focused field recording system minimizes high frequency loss, eliminating undue equalization and achieving a wider dynamic range.

Stereo Tape Deck

AC Servo Motor Direct Capstan Drive System

6 Head system Automatic and manual Reverse Recording and Playback

One each GX forward recording, GX reverse recording, GX forward playback, GX reverse playback, forward erase, and reverse erase head make up the superior GX Head reverse recording and Playback system of this model. The quality and special process of the GX Head materials result in a wider dynamic range, better high frequency characteristics and tone quality and longer lasting performance. Manual Reverse Button and Automatic Sensing Tape Reverse completely eliminate the necessity of inverting reels by hand.

 

Symmetrical Head Block Layout for identical performance in both directions.

The arrangement of the head block is completely symmetrical in relation to the center capstan. The short and equi-distant tape path within the head block and between heads and reel tables on both sides assure identical performance in both directions. Tension Arms on both the take-up and supply reel sides provide perfect tape tension, also contributing to operating stability.

AC Servo Motor for capstan drive, Wow and Flutter reduced to 0,06.

The GX-265D employs a 3 motor drive system with a new AC Servo Motor for direct capstan drive, Rubber belts, flywheels, etc. are eliminated for reduced interference. This coupled with the center capstan system of this model reduces wow and flutter to an amazing 0,06%.

 

Microphone/Line Mixing

Individual Microphone and Line Input Level Controls and a built-in mic-line mixing circuit facilitate easy sound mixing from two separate sources.

Quick Pause Control

Depress the pause Switch to immediately suspend reel movement. When Pause mode is effected, the pinch wheel separates from the capstan by only 0,5 mm for a quick and smooth start when released. Especially convenient for editing tape.

Dual Monitoring

Tape/Source Monitor Switch enables comparison of source signals with just records signals for more professional recording results.

Automatic Stop

The Tension Arm/Stop lever drops at the end of the tape, activating an automatic stop mechanism which completely stops reel movement for operating safety.

Individual Track Selectors for Monaural or Stereo Preformance

Recording mode can be effected using individual left or right channel selectors or both channels simultaneously. A Recording indicator Lamp lights to confirm recording mode.

Output Level Control Enables Connection with any Amplifier

An Output Level Control facilitates adjustment of output level to correspond with your amplifier input.

Tape Selector Switch

A Tape Selector Switch facilitates the use of Low Noise or Wide Range tape. While high performance low noise tape is standard for this machine, the ability to use wide range tape further extends high range frequency response.

Sony TC756-2 reel-to-reel

The Sony TC756 set new records for performance of home tape decks.

Hirsch-Houck Laboratories further noted. "The dynamic range, distortion, flutter and frequency response performance are so far beyond the limitations of conventional program material that its virtues can hardly be appreciated".

 

The Sony TC756-2 features a closed loop dual capstan tape drive system that reduces wow and flutter to a minimum of 0,03% , logic controlled transport functions that permit the feather-touch control buttons to be operated in any sequence, at any time without spilling or damaging tape: an AC servo control capstan motor and an eight-pole induction motor for each of the two reels; a record equalization selector switch for maximum record and playback characteristics with either normal or special tapes; microphone attenuators that eliminate distortion caused by overdriving the microphone pre-amplifier stage when using sensitive condenser mics; tape/source monitoring switches that allow instantaneous comparison of program source to the actual recording; a mechanical memory capability that allows the machine to turn itself on and off automatically for unattended recording; and a full, two-year guarantee.

In addition, the TC756-2 offers 15 and 7-1/2 ips tape speeds; Ferrite & Ferrite 2-track/2-channel stereo three-head configuration; and symphase recording that allows you to record FM matrix or SQ** 4-channel sources for playback through a decoder-equipped 4-channel amplifier with virtually non-existent phase differences between channels.

The Sony TC756-2 is representative of the prestigious Sony 700 Series - the five best three-motor 10-1/2" reel home tape decks that Sony has ever engineered.

Cross-Field Head

On conventional recorders the signal and bias are applied to the same recording head. Therefore the frequencies recorded, especially the high frequency component of the recorded signal tend to be attenuated or erased by the effect of the bias field.

On the exclusive Akai Cross0Field Head which was developed by Akai for practical use the signal and bias heads are mounted in opposition with their centres slightly off. As the recorded signal is entirely unaffected by the prevailing effect of the entire frequency spectrum with maximum fidelity.

 

Sensing Tape Continuous Reverse

Automatic reverse with metallic sensing tape is used for playback only. Reverse operation will occur when metalic sensing tape on prerecorded tape makes contact with the Sensing PIN. Put metallic sensing tape as the desired reverse point on shiny side of the prerecorded tape and another metallic sensing tape at the desired reverse point  on dull side of the prerecorded tape. So, the M-10 will give continuous playback in both directions between two points
