KS Series Amplifiers
- Compact, powerful, dynamic, and clear design
- Analog Class-H
- No radio reception issues
- Class G/H amplifiers developed by Robert Zeff
- Very high damping factor, very good efficiency, and top sound quality.
In Class H, even the power supply voltage is modulated by the input signal, meaning the rail voltage is practically continuously variable from a certain value, thus further improving efficiency.
This power supply technology is significantly more complex than that of conventional Class A/B amplifiers with a single, fixed rail voltage, and it is no wonder that only a few manufacturers dare to tackle the Class G/H topic at all.
The output stage in Class G & H is built identically to the well-known Class A/B amplifier circuit. This is the major difference from the Class D variants used in other compact amplifiers, which always require sound-degrading and distortion-promoting output filters.
Class G/H thus combines low power consumption with outstanding sound capabilities.
