Presenting the ACCUSTIC ARTS® AMP IV, an epitome of excellence as a dual-mono reference power amplifier. Indulge in perfection with individual power supplies for each amplifier channel, and revel in the prowess of 20 carefully chosen MOS-FET output transistors.
Experience power reserves galore with two magnetically shielded and encapsulated toroidal core transformers. Boasting an impressive 160,000 µF power supply capacity, along with premium capacitors “Made in Germany,” it promises optimal smoothing and unwavering performance.
Speaker control reaches its pinnacle with an exceptionally high damping factor, further enhanced by ACCUSTIC ARTS® damping factor linearization. Equipped with professional protective circuits, the AMP IV ensures consistent quality by averting clipping, oscillations, and excessive DC offset.
Operational safety is paramount, evidenced by the integrated switch-on current limitation. With generously dimensioned heat sinks, the AMP IV maintains a constant low operating temperature. Balanced (XLR) and unbalanced (RCA) inputs are thoughtfully switchable for convenience.
Crafted with precision, every component and part is selected for quality. Gold-plated bi-wiring/bi-amping speaker terminals and WBT loudspeaker terminals assure superior connectivity. Encased within a stable, resonance-optimized aluminum housing with an inlay of high-gloss polished and chromed brass, the AMP IV is an artistic marvel.
Delve into the pinnacle of audio craftsmanship with the ACCUSTIC ARTS® AMP IV, a testament to sonic finesse, meticulously “Handmade in Germany.”
