Curious where the name Io comes from?

Curious where the name Io comes from?

Contrary to popular belief, our name does not stand for Input/Output or In/Out (although we do love the double meaning).

The Io Audio Technologies name stems from one of the four Galilean moons of Jupiter, which borrowed its name from Greek mythology. Io was a priestess of Hera and one of the many lovers of Zeus (considered to be the most beautiful).

Nowadays, you can spot Io completing its orbit around Jupiter as the most geologically active object in the solar system. It has over 225 volcanoes, all of which contribute to its sulfuric color.
