ATC SIA2-100 – Hi-End Integrated Amplifier

SIA2-100 – ATC's compact Hi-End integrated amplifier

ATC's SIA2-100 is a Hi End level and extremely versatile integrated amplifier, capable of driving small and medium sized speakers with extreme authority, precision and control, and designed as the ideal partner for the Entry Series. of the same Brand.

Hand-built in the UK to ATC's exacting standards with the aim of extremely analytical, transparent and detailed reproduction.

The heart of the SIA2-100 is a class AB amplifier delivering 100 W per channel (into 8 Ohm) with an extraordinarily dynamic and powerful output. The output stage, derived from the amplifier modules of the Classic Series speakers, is made with discrete components – with two pairs of MOSFETs per side –  characterized by a wide frequency response and extremely low distortion.

A peak limiter protects the speakers in case of overdrive and the amplifier and pre-amp sections have separate power supplies for better signal management.

The SIA2-100 offers all the connectivity required by the most technologically advanced music lovers. Input selection is via a dedicated button on the front panel, and output volume is adjusted via a precision potentiometer. All SIA2-100 functions can also be controlled via the remote control – included in the package.

The understated style makes it easy to match with any other Hi Fi component, while its compact size makes it easy to place in any home space.

Wide versatility

Among the analog inputs, we find two stereo RCA line-in inputs on the rear panel and a 3.5 mm minijack input on the front panel for connecting small portable devices. For digital sources, there is a Toslink optical input, a coaxial S/PDIF input, and a USB Type-B input.

At the heart of the digital sources is a high-quality AKM DAC capable of up to 32-bit 384kHz and native DSD256 decoding for PC and DSD128 for Mac, complemented by a Class A headphone amplifier.

Power outputs include two pairs of 4mm connectors for connecting a single pair of speakers, and a front-panel mounted headphone output with a 6.35mm jack socket.
