The Atoll IN200 Evolution is a next-generation integrated amplifier that combines elegance with high-performance engineering. Its refined design features an 8 mm thick brushed aluminum front panel, complemented by two large rotary knobs and a low-consumption white OLED display. The sturdy 1.5 mm thick metal chassis minimizes mechanical vibrations, while the perforated top cover enhances heat dissipation.
Internally, the amplifier employs a dual mono architecture with two 340 VA toroidal transformers, ensuring excellent channel separation and dynamic sound reproduction. The combination of bipolar transistors in the differential input stages and MOSFET transistors in the output stages contributes to high linearity and minimal distortion. Its 59,220 µF filtering capacity and carefully selected MKP capacitors provide the energy reserves and signal integrity needed for refined, expressive musical reproduction.
The Atoll IN200 Evolution can receive the following optional boards:
- DAC boards: DA100 and DA200.
- PHONO boards: P50 and P100 (can be combined with DAC boards).
Atoll Electronique’s philosophy is more than using high-performance schematics: it’s a consistent approach and rational design, implementing the highest-quality components while maintaining an exceptional price-performance ratio.
We opted for metal chassis, front panels, and discrete component circuits biased to Class A for the preamplifiers and Class A/B for the amplifiers. The power transistors we use are MOSFETs because they offer the advantage of high efficiency with remarkable audio performance.
We strive to satisfy our customers to the maximum by offering them products of the highest quality. The reward for our efforts: musicality, fluidity, richness of timbre and sound detail, an extraordinarily realistic liveliness for a faithful reproduction of your favourite music. It is essential to enhance the enthusiasm of a vast panel of customers since the creation of Atoll has unanimously validated our efforts, an enthusiasm confirmed by numerous distinctions awarded by critics in France and abroad.
All components are inserted and welded at the main factory in France (Brecey, Normandy). We take great care in the handmade assembly and test procedure, which involves four steps: checking, controlling, and checking each unit before shipment.
The warranty is valid for two years from the date of purchase. The warranty applies to products that have been used correctly and in accordance with the manufacturer's instructions.
