KS300.4 by ARC Audio
Discover the KS300.4, a 4-Channel Amplifier from ARC Audio, which impresses with its outstanding sound quality and versatility. With a high damping factor and very good efficiency, it delivers clear, dynamic sound. Its compact design and elegant appearance make it an ideal choice for your audio setup. The Class G/H amplifiers, developed by Robert Zeff, ensure excellent performance without radio reception issues. The amplifier also offers an impressive frequency range and flexible power options that support numerous configurations.
Features of the 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 big 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.
