the traditional method to adjust automatically the dc offset outgoing from solid state audio amplifiers
is completely wrong
from the point of view of the dynamic behaviour and integrity of musical timbre
because it adds compression emphasis to signal depending on the area described by the same
viceversa, the method of Free Run Mode®
allows through a decoupling of balanced capacitors
a proper transfer of information
and returns a natural sounding.
