描述

vs 20 big

The VS-20 is sustained ultra-low impedance caplbility. High voltage two-step output circuit.The VS-20 ultra-low distortion class AB output circuit.

  • Available 4 ohm and 8 ohm load for bridge mode.
  • High frequency power supply.
  • Logical LED meters are present for power IN/OUTPUT level.
  • Ultra lowest in-rush current.
  • Flip-flop controlled full protection circuitry.
  • 1.2mm steel chassis and 2U space.
  • 2000W(1000W per CH) at 4 ohms 0.05% THD 20Hz~40kHz.
  • Class AB output circuit with STK CTLL module for Control In/Out level clipping.
