TechDAS High End Turntables
The new Air Force IV is a new benchmark in analog sound.
A new benchmark in analog sound. Driven by TechDAS’ innovative ‘air’ technologies, this turntable realizes our vision of ultimate analog reproduction
The TechDAS Air Force turntables feature unique pneumatic technologies including air bearing that absolutely isolates the rotating platter and the record from any vibration. Additionally, our vacuum LP hold-down system clamps an LP onto the platter. With these “air” technologies, the Air Force turntables achieve an unparalleled sound quality, compared to conventional analog turntables.

The all new Air Force 10 tonearm
TechDAS Air Force 10 tonearm incorporates a culmination of innovative vacuum hold-down and air bearing technologies, which were originally developed for TechDAS Air Force turntables. Additionally, it draws upon our extensive expertise in precision machining, particularly with titanium and tungsten materials.
After dedicating nearly three years to the development and design of this new tonearm, we are thrilled to present a product that features an exceptionally smooth and precise motion, thanks to the advanced air bearing technologies. This breakthrough enables the faithful reproduction of even the most subtle details embedded within the grooves of vinyl records, immersing you in an unparalleled “you-are-there” feeling and experience. Furthermore, the tonearm’s revolutionary arm tube and main body benefit from the exceptional damping characteristics of the exotic materials and finishes used in their construction. This damping capability ensures ultimate silence and faithfully conveys every piece of information captured by the cartridge, delivering an audio experience of unmatched quality.
