The advanced 2nd-generation Class-D amplification line integrates a high-pitched analog circuit and a bass Class-D circuit design, significantly reducing harmonic distortion, treble drift, and bass deficiencies for superior sound quality. Featuring two dedicated high-power channels, it delivers up to 100W at 8Ω for treble and 650W at 4Ω for bass. Its full-voltage power supply technology, embedded in a world-class amplifier module, supports automatic switching between 110V-130V and 180V-250V for seamless global operation. A robust protection circuit safeguards against DC faults, overheating, overload, voltage fluctuations, and limiting issues, ensuring long-term reliability. The external A/D and D/A professional audio technology offers a 48K sampling rate with a dynamic range of +15dB, alongside an audio processor with 2-in/3-out configuration (system uses 1-in/2-out). Additionally, the module features an efficient cooling structure, with a compact product size of 420mm × 160mm.
