Professional Power Amplifier
Steel S13.4 is a professional power amplifier with a maximum output power of 4 x 1220W @ 8-ohm / 4 x 1670W @ 4-ohm and a maximum bridged output power of 2 x 4000W (RMS) @ 8-ohm. With a performance that stands out for its very low distortion and high fidelity, Steel S13.4 is equipped with a switching-mode power supply. Precisely thanks to the design of its power supply, the amplifier allows the peak power to follow the dynamic range of the musical program, being able to reproduce up to twice the RMS power, without clipping. This translates, basically, into peaks with much more dynamic range than a conventional-source amplifier. As one would expect in amplifiers of this range, the whole Steel series is equipped with a very efficient ventilation and has a comprehensive section of protections, to assure its correct operation in the most demanding situations.
