TechDAS Air Force IV
“A new benchmark in analog sound. Driven by TechDAS’ innovative ‘air’ technologies, this turntable realizes our vision of the 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.”
“Today we believe analog sound must evolve beyond its past forms, after more than 30 years of the digital era.
Our pursuit of superior analog sound seeks to push the boundaries of sound-to-noise ratio, drawing inspiration from advancements in modern digital audio.
TechDAS technologies deliver cutting-edge analog sound, redefining performance with precision and innovation.”
“With these technologies the Air Force turntables have distinguished themselves from conventional turntables in terms of sound and performance.
While most turntables on the market deliver a similar sound from that of the old analog age, in our opinion, analog sound should not remain static, much the same as we have witnessed decades of advancements in the digital audio sector.”
Precision Machined One-Piece Platter
The Air force IV features a Precision Machined One-Piece Platter, a hallmark of TechDAS higher-end models
The Air Force IV turntable employs a heavy-weight one-piece platter machined from solid A5056 alloy while the entry model, Air Force V Premium uses a dual platter system. The result is overall improvement in sound quality such as an extended frequency range and noticeably enhanced dynamics.
Combined with our air bearing system, the 9kg platter allows for an extraordinary low noise floor. Its tapered spindle absorbs any swaying of an off center LP. On top of the platter is applied a special thin pad made of a damping and antistatic material to protect records.
Elevating the Entry-Level Experience with Core Air Force Technologies
The Air Force IV is a model uniquely packaged for a higher level of listening experience compared to the popular entry model, Air Force V Premium. While minimizing increase in footprint, Air Force IV has a low vibration, 2-phase 4-pole AC synchronous motor, which is separated and isolated from the main chassis as in the upper models.
The drive belt is a 4mm flat belt in width; the same one used in the upper models. Made of surface polished polyester fiber, this belt ensures stable rotation and quickly brings the heavy platter to a rated speed. By driving the platter with a separated motor unit, it realizes an extremely high signal-to-noise ratio.
The Air Force IV sits on four suspension feet incorporating specialized damping materials as the Air Force III Premium S, so that it optimally blocks external vibrations and provides an excellent vibration proof property.
Despite its compact body, it can accommodate up to three tonearms.
Benefitting from various technologies developed for its upper models, the Air Force IV realizes high-resolution sound imaging and enhanced sound quality while remaining compact in size.
