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 anodised, with high-precision engraving. The side heatsinks are machined from solid aluminium blocks to absorb mechanical vibrations and ensure perfect heat dissipation.

Features

Front panel in 10 mm brushed, micro-blasted and anodised aluminium,
high-precision engraving.
Mass-machined aluminium heatsink and buttons.
2 mm steel chassis.
Two toroidal transformers: 1050 VA (audio) + 1,6 VA (control logic).
High quality shielded MKP link capacitors.
Integral double mono structure:
– Separate windings for each channel.
– One 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, low feedback.
Power stages with MOS-FET transistors (8 per channel) rigorously matched.
Precise adjustment of the balance, possibility to memorise it.
Possibility of choosing the standby mode: Low consumption or preheating.
Configurable buttons backlighting.
High contrast OLED display: ON or OFF mode (after 5 seconds of inaction).
ATOLL global remote control delivered as standard.

Connectivity

2 XLR inputs.
5 Line inputs: AUX or PHONO (option) CD, TUNER, DVD, TAPE.
1 BYPASS input.
1 12V Trigger output.
Possibility of adding the DA200 digital board (optional):
