TechDAS Air Force One
The reference Air Force One analog turntable by TechDAS ushers 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”.
Incredible music is the outcome generated from air vibration, where the hearts of people are moved and immersed in the sound. In the case of analog recording and its playback a very high-precision system was created. Waveforms containing this analogue data are imprinted in a microgroove which is then extracted as vibrations to be then reproduced in a music system. In this process the turntable is a crucial element to allow a cartridge to accomplish it’s role of picking up the music imprinted in the records. Due to its extreme sensitive to micro-vibration a careful approach is thus required to ensure any displeasing and unwanted vibrations are systematically and thoroughly eliminated at source.
The air bearing
Primarily it is important for a turntable to achieve accurate and a noise free stable rotation. As enough inertia is required to get a stable rotation, the turntable platter has to be heavyweight and as stated below, this turntable is a heavyweight one as well. On the other hand however, as the platter load on the bearings is so heavy, a deterioration of the bearings over time may progress and cause frictional vibrations or degradation of rotation accuracies, even with a precision product.
The disc suction & the air suspension system
Just one press on the SUCTION button right after setting a disc on the platter holds down the disc while the platter itself is floating. You can see in a split second, as a result, a completely flat disc surface and most of the vertical motion by the tonearm disappears and the potential capability of the cartridge exerts its performance to the full.
As a disc becomes one with the platter due to vacuum suction, maleficent sympathetic vibrations are cleared. And moreover, as the disc plate is attracted by means of reducing the atmospheric pressure in the air chamber located internally in the platter, this system enhances damping characteristics of the platter itself, suppress sympathetic vibrations and accordingly signal-to-noise sensitivity improves drastically. After that, a press on the SUCTION button again allows full evacuation instantly enough to release suction of a disc plate at the same time.
The air pump & power supply
This system is composed of a turntable main body, and an air pump / power supply / air condenser unit.
The air pump is a high-performance motor-powered air pump enclosed in a die-cast case and provides incomparable quietness compared to conventional simplified vibration motors and additionally a unique rubber suspension scrupulously eliminates micro vibrations. In addition to the above mechanism, a total of 4 distinct power supplies for a motor driving, a rotation control circuit, an operating circuit and for LED are enclosed in this unit. By each part specialized with a dedicated power supply it is achieved to ensure sufficient power to drive a motor and to enhance the performance of each part. Also by isolating those power supplies from the turntable main body, the electric interference to the music signals transmitted from the cartridge is cancelled and that results in superior playback.
