Presentation
The SLA-4 ART incorporates an advanced SmartFan cooling system. This fan, dependent on internal temperature, operates at different levels to ensure that the amp remains cool and performing even during long usage sessions.
The discrete and linear design of the SLA-4, combined with its toroidal transformer, ensures very low sound distortion and optimal energy efficiency. Balanced TRS and Euroblock inputs, as well as multi-way terminal outputs, enable rapid, modification-free integration into any professional audio system.
