Features:

  • ABACUS power transconductance amplifier:
    – No post-pulse oscillations of membrane
    – Damping factor virtually infinitely high
    – Precise bass
    – Loudspeaker properties are idealized
    – driving low impedance (<2Ohm) without any problems
  • Stereo/Mono switchable
  • Line-input via Neutrik high end RCA
  • Balanced Input via Neutrik combinded XLR/TRS
  • High precision instrumentation amplifier in input stage
  • High precision operational amplifiers in the signal path
  • low number of amplifier stages and capacitors in the signal path
  • Works as linear integrated amplifier
  • ALPS precision-potentiometer
  • Double binding posts allow bi-wiring down to the PCB
  • Microcontroller for:
    – Protection circuit protecting loudspeaker and amplifier
    – DC-offset-protection
    – Overheat protection
    – Automatic switch on
    – Softstart
    – Suppression of noise at power switch-on
  • 500VA toroidal transformer
  • Seperate supply of digital part, input stage and power amp
  • Suplly of the power amps with 3rd order filter each
  • seperate capacitor banks for each channel, each 2×40.000µF, 160.000µF in total
  • Stable aluminum chassis
  • Comes with power cord and user manual
