CALL TO ORDER OPTIONAL BOARDS

The IN400 EVO is an integrated amp-preamp with high musical capacity. The concept is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is made of 2 mm steel, and the front face is 10 mm aluminium, brushed, micro-blasted, and anodized, with high-precision engraving. The side heatsinks are machined from solid aluminium blocks to absorb mechanical vibrations and ensure perfect heat dissipation.

• Front face in 10 mm brushed, micro-blasted and anodised aluminium, high-precision engraving.
• Heatsink and buttons in billet aluminium.
• 2 mm steel frame.
• Two toroidal transformers: 1050 VA (audio) + 1.6 VA (control logic).
• Integral double mono structure:
  – Separate windings for the tracks.
  – 1 attenuator per channel (with switched resistors).
• Bipolar transistor input stages.
• Current sources with bipolar transistors and LEDs to ensure perfect voltage stability.

• Darlington transistor driver stages.
• Audio stages with perfectly symmetrical structure and very low counter-reaction.
• Power stages with MOS FET transistors (8 per channel) are rigorously matched.
• Precise adjustment of the balance and the possibility of memorising it.
• Possibility of choosing the standby mode: Low consumption or preheating.
• Configurable button backlighting.
• High contrast OLED display: ON or OFF mode (after 5 seconds of inaction).
• ATOLL global remote control delivered as standard.
• The IN400 Evolution can receive the following optional boards:
  – DAC boards: DA100 and DA200.
  – PHONO boards: P50 and P100 (can be combined with DAC boards).
