ATC SIA2-150 Stereo Integrated Amplifier

The ATC SIA2-150 MK2 is a high-performance 150-per-channel Stereo Integrated Amplifier perfectly suited to driving ATC speakers or any other high-end speakers of your choice, Building on its professional studio audio experience, ATC has designed a powerhouse of an amplifier which has tremendous power and at the same time amazing detail and delicacy. The balance of features and power output very carefully in order to offer a Hi-Fi component that will meet a very wide range of requirements. 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 preserves subtle low-level information and ensures that the whole combination of the pre and power amplifier remains neutral and totally free of colourations.

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!

Who are ATC

Formed in 1974 by Billy Woodman to manufacture custom drive units for the professional sound industry, ATC quickly made its mark with the 12″ PA75-314 driver, a design capable of handling more power and producing less distortion at a higher sound pressure level than any other unit on the market. Having established a market for reference quality precision-made monitors, a succession of smaller ATC speakers then evolved, ranging from SCM7s through 10s and 20s. Available in both active and passive versions, they offered elite ATC performance and reliability to many new customers.

Through ATC’s commitment to multi-channel mastering and its direct involvement with leading players in the professional audio industry including Sony Music and Telarc, ATC’s products are installed at some of the world’s most prestigious multi-channel studios and auditoria. Wherever the best is required you will find ATC.
