We never actually discussed why you need this. I'm assuming three or four people (i.e. more than two) will use headphones and want their own volume (though not their own mix; that's much more involved but possible). If you only have two people using headphones, then I would have recommended long headphone extension cords.

As the headphone amp only has 1/4" input jacks, that lets out any consideration of digital.
