Can I ask wtf anyone needs 10 inputs for doing what we do? I get four channels but ten? Hosting others mics?
Reality TV shows. They can quickly get to crazy high track counts!
Heck, even myself when I was doing an ultra low budget feature film was often maxing out my F4 and recording 6 tracks at once, and wishing I could run just one or two more wireless into it....
And if I was not doing this solo, but with a team in my sound department (wouldn't a 3 man sound crew be the dream! ahh), then you could easily throw on another five tracks to that.
