ATC SIA2-150 – Stereo Integrated Amplifier

The ATC SIA2-150 is a high-performance stereo integrated amplifier for listeners who want a simple all-analogue system without losing sound quality. It combines ATC’s discrete preamp design with their proven MOSFET Class A/B power amplifier. As a result, it delivers strong control, clarity, and musical detail.

In addition, the SIA2-150 offers a straightforward solution for driving passive loudspeakers. Therefore, it fits well in both simple and high-quality stereo systems.

Integrated preamp and power design

The SIA2-150 uses discrete Class A low-noise input stages together with MOSFET Class A/B output stages. In addition, this design keeps the signal path clean and stable. As a result, it delivers natural sound with strong dynamics and low distortion.

High power output

The amplifier delivers 150 watts per channel. Furthermore, it keeps full control and stable performance across a wide range of loudspeakers. Therefore, it maintains clarity and precision even at higher listening levels.

Flexible analogue connectivity

The SIA2-150 includes 5 stereo RCA/phono inputs and 3 RCA/phono outputs for preamp, subwoofer, and tape use. In addition, this wide connection set makes it easy to integrate different analogue sources.

Headphone output and control

The built-in headphone amplifier allows direct listening. In addition, the IR remote control makes daily use simple and convenient.

System design and performance

The SIA2-150 is designed as a complete all-analogue integrated amplifier. Therefore, it combines power, control, and simplicity in one unit. In addition, it keeps ATC’s neutral and accurate sound character.

Build and design

The SIA2-150 is hand built in the UK and designed for long-term reliability. In addition, ATC backs it with a 6-year warranty.
