KS2500.1 by ARC Audio
The KS2500.1 from ARC Audio is a 1-Channel Amplifier that stands out for its powerful and dynamic performance. Part of the KS series, it impresses with a compact design and the use of analog Class-H technology developed by Robert Zeff. The amplifier offers top sound quality through a high damping factor and good efficiency. With a power output of up to 2500 Watts at 1 Ohm and a frequency range of 20 Hz to 250 kHz, the KS2500.1 delivers precise audio quality. Thanks to its thoughtful construction, issues with radio reception are eliminated, further underscoring the reliability of this model.
KS Series Amplifiers
- Compact, powerful, dynamic, and clear design
- Analog Class-H
- No radio reception problems
- 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, which further improves efficiency.
This power supply technology is significantly more complex than that of conventional Class A/B amplifiers with a single, fixed rail voltage, so 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.
