Steel S15.2
Professional Power Amplifier
Steel S15.2 is a professional power amplifier with a
maximum output power of 2 x 1520W @ 8-ohm / 2
x 2300W @ 4-ohm and a maximum bridged output
power of 1 x 4600W (RMS) @ 8-ohm. With a perfor-
mance that stands out for its very low distortion
and high fidelity, Steel S15.2 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 trans-
lates, basically, into peaks with much more dynam-
ic 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.
