Atoll Electronique IN100 Signature Integrated Amplifier

$2,795.00 inc GST

The Atoll Electronique IN100 Signature Integrated Amplifier is a double mono audiophile model using generously sized high quality electronic components.

It is capable of developing up to 2×100 watts RMS into 8 ohms and 2×180 watts RMS into 4 ohms. It succeeds the emblematic Atoll IN100 SE amplifier from which it is mainly distinguished by an optimized power supply circuit giving it greater dynamics and richer musicality.


Atoll Electronique IN100 Signature Integrated Amplifier

Like all the electronics of the tricolor brand, the Atoll Electronique IN100 Signature Integrated Amplifier is designed according to strict audiophile standards. It thus adopts a double mono design using two oversized 340 VA toroidal transformers, giving it a total power of 680 VA and a current capacity of 31,474 µF. By comparison, this current capacity is significantly higher than most home theater receivers that need to power multiple speakers. Thanks to this solid power supply, the Atoll IN100 Signature amp is able to keep pace at high volume and in the low register. It can deliver up to 100 watts of power into 8 ohms and 140 watts into 4 ohms. The Atoll IN100 Signature ampis thus able to power the vast majority of loudspeakers without the slightest difficulty.
