Relate Product:  KAi Series

  1.  Combined with effective power systems, detail, intensity, razor, creating a wonderful space for entertainment sound. Working in an ideal linear Class A output state, output stage of drive tube bringing the warmth of tone A-level amplifier.
  2. Temperature gain as well as power clamp control technology, protects the high frequency driver from excess power without interrupting the performance. Meanwhile continuous output power with load make system more reliable. Whether amplifier continuous load or not is an important indicator of working in high-burden continuously. Effective temperature compensation to ensure a long continuous working state reliability.
  3. Light control volume control technology, dramatically reducing the background noise, makes sound wider and more pure. The noise floor is different from the signal to noise ratio, when you pursue a more pure sound, wider frequency response range, any impact on the sound elements will be minimized.
  4. KA600,KA800 using switching power supply,KA1200,KA1800 using traditional ring transformer.
