Atoll IN200 EVO

The Atoll IN200 Evolution (EVO) is a high-performance integrated amplifier designed and handcrafted in France. Positioned in the upper-mid tier of Atoll Electronique's line, the EVO revision represents a significant upgrade over previous generations (like the IN200 Signature), incorporating refined power handling, lower noise, and internal design enhancements derived from Atoll's flagship models.

Key Features & Design Architecture

• Dual-Mono Topology: Powered by twin 340 VA toroidal transformers (plus a separate 10 VA transformer for the logic/display), ensuring complete channel separation and dynamic independence.

• MOS-FET Power Stage: Features a double push-pull MOS-FET output stage biased in Class A/B. It runs in pure Class A for lower power demands before transitioning smoothly to Class B.

• High Capacitance & Low Noise: Uses high-end, custom ESR filter capacitors (59,220 µF total) and shielded Mundorf MKP capacitors to deliver fast dynamic transients without adding distortion.

• Upgraded Hardware: Built with custom-designed tellurium copper speaker binding posts, double-sided gold/nickel printed circuit boards, and an 8 mm brushed aluminum front panel.

• OLED Interface: Features a low-consumption, high-contrast white OLED display with customizable features, including the ability to rename inputs and adjust channel balance.
