The Atoll IN400se integrated amp-preamp was meticulously designed to achieve exceptional musical reproduction and visual excellence. With regards to its mechanical construction, the chassis is constructed using 2 mm thick steel, while the front panel is made of 10 mm aluminium. The strategically placed lateral fins effectively dissipate internal heat and minimize mechanical vibrations.

The electrical stages of the amplifier are designed as strict double mono setups, featuring dedicated attenuators for each channel and two distinct star masses. Every component has undergone a rigorous selection process, and the overall circuitry has been optimized to finely adjust bias currents and feedback rates. The ultimate objective is to deliver maximum power and energy across all frequency ranges, ensuring an immersive listening experience that seamlessly combines sonic accuracy, natural fluidity, and harmonic richness.
