KS300.2 by ARC Audio
The KS300.2 from ARC Audio is a 2-Channel Amplifier and part of the renowned KS Series. This model impresses with its compact size, high power, and a clear, dynamic design. Thanks to the analog Class-H technology, it delivers excellent sound quality without radio reception issues. The amplifier features a remarkably high damping factor and outstanding efficiency. Developed by Robert Zeff, the KS300.2 combines low power consumption with exceptional sound capabilities. Additional features include flexible power supply voltage and crossovers.
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, so the rail voltage is practically continuously variable from a certain value, 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.
