AI-SONIC S2-A60.4
AI-Sonic S2 amplifiers. Designed in Finland by AI-Group.
With excellent sound quality, versatile control features, and the ability to connect to any system to drive any speaker, it's hard to beat the Ai-Sonic S2 amplifiers.
The ambitious goal was to design and implement an amplifier range that offers the best possible sound quality in its price range. The work began by designing a unique cooling profile.
Maximizing cooling and minimizing the physical size of the devices continued with the PCB design. The locations of the components on the PCB are carefully selected to achieve the smallest possible physical size of the amplifier and efficient component cooling.
The circuit board uses twice as much copper as a standard car amplifier circuit board.
Three years have been spent selecting and testing the components for the AI-Sonic S2 amplifiers. By testing and listening to numerous different parts and combinations of parts, we have found the parts that form the best possible whole in their price range.
All components of AI-Sonic amplifiers are slightly oversized for the amplifier's power output. Dual power supplies are used in larger models.
Optional remote level control. (Note: Only works when LPF is on.) The level control also has power, clip and fault status indicators.
The level control only controls the front channels.
