The integrated amp-preamp IN100 Signature is manufactured with the utmost care. We choose the best possible components to achieve the highest level of sound performance. This rigorous search for perfection involves designing proprietary ATOLL circuits to preserve the integrity of the most subtle musical signals.
- 4 mm brushed aluminium front panel.
- 2×100 W / 8Ω.
- 2 toroidal transformers of 340 VA each.
- ALPS motorized potentiometer.
- Filter capacitors: 4×6800 μF.
- Single push-pull MOS-FET power stage.
- Monitoring loop.
- 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 ATOLL global remote control.
- The IN100 Signature can receive the following optional boards:

CONNECTIVITY
Inputs
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).
Outputs
2 Line preamp outputs (for bi-amplification or to connect a subwoofer).
1 Trigger output (12V).
Various
1 Headphone jack Ø 6,35 mm.
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.
