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.

ATC have been designing and building Professional Studio electronics for many years, and have earned an enviable reputation for the EC23 Active loudspeaker crossover and the associated power amplifiers built into their Active Studio Monitors.

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 SIA2-150, as also used in all ATC Active monitors, delivers the high current and damping to fully control any passive monitor.
