ATC SIA2-100 Integrated Amplifier

ATC SIA2-100 Integrated Amplifier

Compact in size (2/3 width) yet offering high power output and exceptional resolution, this integrated amplifier with on-board DAC is ideally suited to driving ATC’s small & mid-size passive loudspeakers and a very wide range of loudspeakers from other manufacturers.  Understated styling makes it easy to integrate with partnering equipment whilst its small footprint occupies very little space in the home.
