Atoll IN100 Signature Black

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:
            – DAC boards: DA100 and DA200.
            – PHONO boards: P50 and P100 (can be combined with DAC boards).

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).
1 Ø 6,35 mm headphone jack output.

Divers
Possibility of adding DA100 or DA200 digital boards (optional).

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.

Optional remote control allows control of the following products: Integrated, Preamps, CD players, Tuners, and DACs.

“There’s also a lot of musicality when listening to the Jazz Hi-Res CD Sampler released by Universal Music, made in Japan, a publisher that doesn’t want to hear about streaming. Cannonball Adderley, Miles Davis, John Coltrane, Stan Getz and many other big names are reviewed in 352.8kHz/24 bit. The CD100 and the IN100 know how to handle this avalanche of qualities. The placement of the instruments and voices in space is striking and perfectly balanced. We are in heaven, and are starting, for pleasure, a marathon listening to the most beautiful records in our collection.”
