KS Series Power Amplifiers
  • Compact, powerful, dynamic and clear design
  • Analog Class-H
  • No radio reception problems
  • Class G/H power amplifiers developed by Robert Zeff
  • Very high damping factor, very good efficiency and top sound quality.

With Class H even the power supply voltage is modulated by the input signal, so the railvoltage is practically infinitely variable above a certain value, which improves the efficiency even more.

This power supply technology is much more complex than conventional Class A/B power amplifiers with a single, fixed rail voltage, so it is no wonder that only a few manufacturers even dare to tackle the subject of Class G/H.

The output stage of Class G & H is identical to the known Class A/B amplifier circuit. This is the big difference to the Class D variants used in other compact amplifiers, which always require sound-reducing and distortion-promoting output filters.

Class G/H thus combines low power requirements with outstanding sonic capabilities.

Features:

  • 4-channel amplifier
  • 4 x 90 watts @ 4 ohms
  • 4 x 175 watts @ 2 ohms
  • 2 x 350 Watt @ 4 Ohm
  • Frequency range: 5 Hz - 50 kHz
  • Crossovers: HP/LP Filter 55 Hz - 5.5 kHz
  • Bass Boost: 18 dB @ 45 Hz
  • Signal-to-noise ratio: 95 dB
  • Input sensitivity (low level): 200mV - 3.5V
  • Maximum Current Draw: 85 Amps @ 800 Watts (1% THD)
  • Quiescent current consumption: 1.14 amps
  • Dimensions: 29 cm x 20 cm x 6 cm
