Features

  • Three sets of balanced inputs (also provide three sets of RCA inputs).
  • One set of balanced output (also provide one set of RCA output).
  • Patented design (WUBA – Wideband Unity Balanced Amplifier) improves low-level balanced signal integrity.
  • Use of wideband MOSFET current source to improve Common-Mode Rejection Ratio (CMRR).
  • No load resistors, no buffers and no followers.
  • No global negative feedback.
  • No semiconductor transistors, op-amps and transformers for signal amplification.
  • Wide bandwidth, 500kHz.
  • Dual mono channel design with premium dual mono power supply.
  • Premium grade R-core power transformer and shielding facility are used to reduce noise and electromagnetic interference.
  • Premium grade signal capacitors and resistors.
  • Modern chassis design improving looking and heat ventilation.
  • Soft-start circuit reduces the inrush current when switching on. It also ensures that in the first 30 seconds a reduced supply voltage is applied to vacuum tubes. This prolongs life of all rectifying diodes, power supply filtering capacitors and vacuum tubes.
