“Our most affordable model that preserves the “Air Force” technologies
The Air Force V has been developed to deliver another dimension of analog sound to more analog enthusiasts at a more affordable price. This model has a similar sized compact chassis as the Air Force III, and by designing an elaborate drive system successfully reduces any motor vibrations.
Thus we have achieved an integration of the motor in the plinth. The result is an even more compact turntable without a separate motor unit that can be fitted with up to four tonearms.”

“The Air Force III turntable is designed as a system with excellent performance and upgradability. It has been developed by extracting the essence of our reference model Air Force One, and reworking these aspects into a more compact and affordable design. It is a true audiophile product in it’s own right.”
Air control technologies
Instead of having built-in insulators, the turntable sits on four feet using a pin point support method with a sufficient howling margin within an appropriate installation environment.
For an environment that needs a larger howling margin, an insulation table based on air insulation technology will be availabl
Above all, the Air Force III ha
s the core air control technologies of the Air Force One, which is the air bearing that enables the platter to float at 30µm above the base, and also has a vacuum hold down for securing the disc.
“The top-of-the-line model for the TechDAS Air Force turntable series with new integrated concepts and technologies further refining the sound, user-friendliness and external finish.
The Air Force One Premium analog turntable by TechDASushers in exquisite design concept to positively exploit the aerodynamic force equivalent to sound energy rather than springs or buffer materials. It is the ultimate mechanism based on a vibration damping design using “Air Force” and utilizes only high-precision finished parts with enough mass to completely avoid any “colour” to the sound, nothing is added or removed. Through the aerodynamic instrumentality of “Air Force” the real magnitude and essence of ultimate analog playback is now a reality. Adverse effects caused by various obstructive oscillations, which used to be arch-nemesis of analog turntables has been thoroughly wiped out by the Air Force.”
Technology used in vinyl reproduction
Descended from the flagship model, the core mechanism contained in the exquisite design concept is designed in such a way to exploit the aerodynamic force equivalent to sound energy to the full. It is a well-known fact that an analog disc is a sensitive and very fragile program source in which waveforms transmitted as air vibrations generated by the original music are im
printed into a microgroove in the record.
The turntable should thus be the key center of the playback process by extracting the original oscillatory waveforms in an authentic way and transmitting these as accurate audio signals. Any signals other than these valuable micro waveforms imprinted on the disc ought to be detected by a stylus as maleficent without exception.
There are specific examples such as frictional vibrations caused by bearings under a rotating turntable platter, vertical vibrations of a tonearm caused by warpage of an analog disc, or vibrations due to some stylus movement resonating with an even flat disc to the contrary and in addition to them, direct vibrations from the floor propagating directly through a turntable. There are surprisingly a constellation of maleficent vibrations. In early turntable design various attempted procedures have been rendered such as improved machining method for bearings, putting a stabilizer weight on the disc plate to reduce warpage and resonance, and supporting the overall player on springs. As a result, it is a fact that no one could accomplish their objectives until today.
As the “Air Force Two” is a arm-free designed turntable, no tonearm is incorporated. The chassis can mount two tonearms at the same time and both 10 inch type or 12 inch type can be accommodated. Standard tonearms with the effective length of 10 inches can be mounted on the right side of the turntable within standard specifications, but also an optionally available arm base for the second tonearm can be installed on the far left of the chassis where a tonearm with the effective length of 12 inches can be mounted. Therefore, both types can be mounted on the turntable. Since additional work is required for each mount to meet individual specifications, the particular tonearms of your choice should be communicated to us prior to the placement of your order.
The critical issues in design for the “Air Force Two” are to achieve price reduction and to ensure the existing performance on par with the flagship reference, the “Air Force One” as a best buy product. Since to manufacture the chassis of the “Air Force One” incurs many costs due to cutting a metallic block by a computerized numerically controlled (CNC) machine, we have successfully switched to the aluminum precision-cast and painting the chassis instead.
As tasting is not only integrally molding the whole of a chassis mechanism but also produces a better volume-production effect, we have successfully accomplished significant cost reduction without sacrifice of performance. The chassis supported by large-size four-legs is of a double-layered structure consisting of an upper layer with complex configurations and a flat but thick lower layer. To secure sufficient strength, not only the thickness but also ribs are employed according to the need. As a result, the total weight reached 32.6Kg. The heavy chassis coated with a calm color of feeling will support the fundamentals of music and sound firmly.
The fabric belt drives the heavyweight platter made of precision cut aluminum. The rotation is supervisory-controlled through a non-contact sensor and a microcomputer resulting in a very high rotational accuracy. turntable platter reaching a weight of 10Kg is manufactured by precision cutting a solid aluminum block (A5056). In analogy with the flagship model, the platter of the “Air Force Two” is equipped with a vacuum disc suction mechanism. In addition, the disc-absorption surface of the upper platter is covered with special thin film damping materials. The rotation of the platter is driven by a fabric belt. On belt for driving the non-stretch polyurethane fiber belt with polished surface is employed in line with the “Air Force One”. Please note that a common rubber belt seems much easier to handle than this belt when replacing. However, given the high-grade playback, for the high-precision heavyweight turntables like the “Air Force One” and the “Air Force Two” belt-drive by a common rubber belt obviously cause a loss of performance due to its elasticity and as a result convincing sound quality is not attainable.
The motor for driving incorporated in the “Air Force Two” is a high-precision AC synchronous motor stored in free-standing rugged aluminum housing. The power supply is stored in the stand-alone cabinet by the name of “Air pump & Power supply Unit” as Power Amplifier Drive ‒ Rotation Control System that watches and controls a rotation speed of the platter through non-contact sensor and maintains a constant speed through speed adjustment microprocessor circuit. Due to outcome using systems including previously mentioned “Air Bearing System” a high rotational stability with less than wow and flutter 0.03% accuracy is achieved. Switching the revolution speed between 33 1/3 rpm and 45 rpm is available and additionally as a maximum 10% pitch control in +/- 0.1% steps of each constant speed is possible, the playbacks with your favorite pitch to suit the discs like instrumental albums become operational.
The “Air Force Two” is configured with a turntable main body, a driving motor in free-standing housing and in addition to them the “Air pump & Power Supply Unit” in a separate case.
The “Air Force Two” is configured with a turntable main body, a driving motor and in addition to them the “Air Pump & Power Supply Unit”. In the “Air Pump & Power Supply Unit” an electric air pump, an air condenser and power supplies for the circuits are installed. The motor-powered air pump enclosed in a robust die-cast case provides incomparable quietness with conventional simplified vibration motors and as an additional configuration a unique rubbersuspension is employed for scrupulously cutting-off micro vibrations. This driving motor is combined with the air condenser which is a tempered glass chamber mechanism where air evacuated from the air pump is stored temporarily and after absorbing the pulsating air flow completely, the processed air is fed for the air bearings and the disc attraction. Other than the above mechanism, total 4 distinct power supplies for a motor driving, a rotation control circuit, an operating circuit and for LED light are enclosed in the unit. By each part specialized with a dedicated power supply it is achieved to ensure rich enough power to drive a motor and to enhance the performance of each part. By also isolating those power supplies from a turntable main body the electric interference to the faint music signals is cancelled and that enables realization of a superior playback.
