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) rigorously matched.
- Precise adjustment of the balance, the possibility of memorizing 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 EVO can receive the following optional cards:
– DA100 and DA200.
– P50 and P100.
