ATC SIA2-150 MK 2 Integrated Amplifier

150 Watt per channel Stereo Integrated Amplifier by ATC. ATC has an enviable heritage of the design and manufacture of no-compromise studio electronics including the power amplifiers included in all ATC Active monitors.

The ATC SCA2 Stereo control pre-amplifier, designed primarily for the purpose of driving Active monitors in both Studio and Hi-Fi installations, has attracted the praise of journalists and recording engineers alike. The combination of ATC power amplifier and ATC control unit in one stylish housing makes a convenient and affordable package offering the finest sound quality possible in a single HiFi component.

ATC has chosen the balance of features and power output very carefully in order to offer a HiFi component that will meet a very wide range of requirements.

The output power of 150W is sufficient to reproduce well recorded material, Rock, Pop, Classical or Jazz at realistic levels in virtually all domestic situations. As designers of the worlds most sophisticated drive units ATC are only too aware of the requirements for a power amplifier to properly drive a real loudspeaker load. The grounded source FET power amplifier in the ATC SIA2-150, as also used in all ATC Active monitors, delivers the high current and damping to fully control any passive monitor.

The ATC SIA2-150 is however a supremely subtle and tender performer, conveying the gentler extreme of recorded dynamics with sensitivity and inner detail only possible when all distortions and non linearities are reduced to levels well below audibility.

The extremely low distortion also explains the tangibility and precision of the stereo sound stage, recreating the full presence of the recording. The simple and direct signal path within the pre amplifier stages of the SIA2-150 preserves subtle low level information and ensures that the whole combination of the pre and power amplifier remains neutral and totally free of colourations.

In fact the ATC SIA2-150 is a perfect match for the absolutely natural and uncoloured reproduction of ATC monitors. A combination that will present your favourite recordings just as the recording engineer intended. He was probably using ATC to master the recording anyway!
