The IN300 Evolution integrated amplifier features reworked power supplies, improved audio performance, and a low-power mode. DAC boards are now optional.

• 8 mm brushed aluminium front panel, micro-blasted and anodised, with high-precision engraving.
• 2 x 150 Wrms / 8Ω.
• 1.5mm thick steel chassis.
• Two 440 VA toroidal transformers for the audio stages plus 10 VA for the digital stages.
• Soft start stage to avoid power surges.
• High-end ABSOLUE CREATIONS internal wiring on the power supply side.
• Filter capacitors: 12 x 6800 μF high-quality capacitors with a low ESR specifically designed for ATOLL.
• High-quality, shielded MKP coupling capacitors.
• Bipolar transistor and LED current sources to ensure perfect voltage stability.

• Triple push-pull MOS-FET power stage.
• Polarisation of the output stages in class A/B.
• Possibility of choosing standby mode: Low consumption or preheating.
• 2 volume attenuators: 1 per channel to maintain the dual mono architecture.
• Possibility to manage balance and memorise it.
• Possibility to rename the inputs.
• High contrast OLED display (on or off mode after 5 seconds of inactivity).
• Double-sided printed circuits with nickel/gold finish.
• ATOLL global remote control supplied as standard.
• The IN300 EVO can receive the following optional boards:
            – DAC boards: DA100 and DA200.
            – PHONO boards: P50 and P100 (can be combined with DAC boards).

• Specific copper speaker output connectors specially manufactured for ATOLL.
• Internal wiring of the speaker outputs with high-end cable.
• Output connectors (RCA) gold-plated.
