Beschreibung
The KS125.4 mini from ARC Audio is a 4-channel amplifier that is characterized by its compactness and impressive performance. It is part of the KS series and has a clear and dynamic design. The use of analog Class-H technology ensures that there are no radio reception problems. Another feature of this model is the Class G/H power amplifiers developed by Robert Zeff, which promise a very high damping factor, high efficiency and the best sound experience. Overall, the KS125.4 mini is an outstanding amplifier that combines low power consumption with excellent sound quality.
The Arc Audio KS125.4 mini 4-channel amplifier impresses with a very high damping factor, very good efficiency and top sound quality.
- 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, so the rail voltage is practically continuously variable from a certain value, which further improves the efficiency.
This power supply technology is significantly 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 topic of Class G/H.
The output stage of Class G & H is identical to the well-known Class A/B amplifier circuit. This is the big difference to the Class D variants used in other compact power amplifiers, which always require output filters that reduce sound and increase distortion.
Class G/H combines low power consumption with outstanding sound capabilities.
