Technical description

Two toroidal, 1300VA transformer, one per channel. Dual mono design. No capacitors in the signal path and only double-side metallized polypropylene film capacitor in the critical points. The internal stages are DC coupled and the offset is reduced by means of an integrating amplifiers. High current capability. The protection and control sections are galvanically insulated from the analog sections to minimize the digital noise. No mains fuse. The mains current is measured at the input of the transformer (with a current probe) and in case of malfunctions it's shutted off. The voltage of both channel is measured by means of optocoupler to avoid any ground loop. The DC offset on the output (loudspeakers) is also monitored by means of optocouplers. The protections are realized with a PLD (Programmable Logic Device); it's faster and more reliable compared to a microcontroller.

Technical features

  • Channels 2
  • Colours 2
  • Power on 8Ω load 200W
  • Power on 4Ω load 400W
  • Power on 2Ω load 800W
  • THD + N (1W, 8Ohm 1 KHz) 0.03 %
  • Slew Rate 50 V/μs
  • Frequency Response(Att. 0dB, -3dB band) 1 Hz - 160 KHz
  • Input Noise(Band limits 0Hz-80kHz/A-weighted) -130 dB
  • SNR > 100 dB
  • Dimensions(HxWxD) 260 x 445 x 460 mm
  • Weight 65.5 Kg
