Description
Atoll Electronique IN400SE Integrated Amplifier
The Atoll Electronique IN400SE Integrated Amplifier is an integrated amplifier/preamplifier with exceptional musical capabilities.
The IN400SE’s design is based on technical and aesthetic choices dedicated to optimal musicality. Mechanically, the chassis is constructed from 2mm steel, while the front panel is made of 10mm aluminum.
The side heat sinks are machined from solid blocks of aluminum to absorb mechanical vibrations and ensure efficient heat dissipation.

Features
- 10mm brushed aluminum front panel.
- Linear power supplies based on toroidal transformers.
- Symmetrical stages with discrete components.
- 8 matched MOS-FET transistors per channel.
- Low power consumption OLED display.
- ATOLL global remote control.
CONNECTIVITY
- Inputs:
2 XLR inputs.
5 Line inputs: AUX or PHONO (optional), CD, TUNER, DVD, TAPE.
1 BY-PASS input. - Outputs:
1 x 12V trigger output.
1 x 6.35mm headphone jack output. - Miscellaneous:
Possibility of adding DA100 or DA200 digital cards (optional).
The electrical stages are rigorously dual-mono with a dedicated attenuator for each channel and two separate star-shaped grounds. Each component was selected by ear, and the circuit was optimized to fine-tune each bias current and feedback ratio.
The ultimate goal is to deliver maximum power with equal energy across all frequency ranges. The result is a listening experience that combines sonic substance with fluidity, naturalness with harmonic richness.
