IN200 Signature

The integrated amp-preamp IN200 Signature is manufactured with the greatest care: we choose the best possible components to achieve the highest level of sound performance. This rigorous search for perfection goes through the design of proprietary ATOLL circuits in order to preserve the integrity of the most subtle musical signals.

  • 8 mm brushed aluminium front panel. 
  • 2×120 W / 8Ω.
  • 2 toroidal transformers of 340 VA chacun.
  • Filter capacitors: 8×6800 μF high quality, low ESR specific for ATOLL.
  • Specific low consumption 5 VA power supply for the digital stages.
  • MOS-FET double push-pull power stage.
  • 2 volume attenuators: 1 per channel to maintain the dual mono architecture.
  • Shielded MKP Mundorf capacitors.
  • Possibility to adjust and memorise the balance.
  • Discrete component audio stages.
  • MKP Technology Link Capacitors.
  • High-performance heat sinks, direct thermal coupling.
  • Double-sided circuit boards with nickel/gold finish.
  • Polarization of output stages in class A/B.
  • Thermal protection.
  • Optional DAC board: same as included in IN300.
  • Optional PHONO boards: P50 and P100, can be combined with the DAC board.
  • ATOLL global remote control.


5 Audio inputs (RCA): AUX (or optional P50 / P100 phono stage), CD, TUNER, DVD, TAPE (IN + OUT).
1 BY-PASS input (used as a power amplifier).

2 Line preamp outputs (for bi-amplification or to connect a subwoofer).
1 Trigger output (12V).

1 Headphone jack Ø 6,35 mm.

Internal wiring of loudspeaker outputs with the specific audio cable.
Gold-plated (RCA) connectors.

Our balanced MOS-FET amplifier circuits offer excellent harmonic gradients and have no memory effect, every moment, the current is immediately delivered to your speakers. This is one of the secrets of the musicality that ATOLL amplifiers enjoy.

“Atoll is one of the electronics manufacturers where we appreciate transparency, which means neutrality, liveliness, and self-effacement in the face of music. With the IN200 Signature, the design is mature, especially when listening to it. No signature of its own, no tonal redundancy from one track to another, but a unique and distinct reading of each score, with now class-A flavours found throughout the entire spectrum and over a wide range of listening levels.”
