The IN400seintegrated amp-preamp was conceived for optimal musical reproduction and visual perfection. From a mechanical point of view, the chassis is made of 2 mm steel and the front panel of 10 mm aluminium. Its lateral fins are designed to optimally dissipate heat from within the case and absorb mechanical vibrations.
10 mm brushed aluminium front panel.
Linear power supplies based on the toroidal transformer.
The electrical stages are strictly double mono with one specific attenuator per channel and two differentiated star masses. Each component has been rigorously selected and the scheme optimized to fine-tune each bias current and feedback rate. The end goal is to deliver maximum power with so much energy in all registers, in order to offer admirable listening combining sound material and fluidity, naturalness and harmonic richness.

“(…) This refreshing, this welcome rejuvenation had been made possible thanks to the close collaboration between Atoll and its metal supplier. In addition, the manufacturer is redoubling its efforts to ensure that most of the components and suppliers come from France or Europe. This is how the chassis are made in Brittany, the front panels are laser cut in Lorraine, the printed circuits come from the Basque Country, the power supplies are made in Rhône-Alpes and the packaging comes from Normandy (…)”.
