R900 Tube Series

R900 1

FEATURES

  • Stereo mode parallel-mono mode and bridge-mono mode are available.
  • The performances of machine is more secure with the protection of DC overload short circuit overheating compression limiting and soft start.
  • A large number of high-precision SMD devices with automatic manufacturing technique ensures the product higherreliability.
  • High efficiency toroidal transformer with magnetic shielding layer prevents interference effectively.
  • Efficient three-level H circuit design with a small size.
  • Automatic transmission fan with optimized cooling system ensures more stable performance of the machine.
