Re: [AH] Behringer X32 and USB cable length

I shouldn=E2=80=99t have written =E2=80=9Canother electrical format=E2=80=9D=
 because many of these USB extenders seem to be optical. My point is =
that they=E2=80=99re no longer USB once you convert to optical, =
ethernet, or any other trick that extends USB beyond the length that it =
was designed for.

As DJ Maytag alluded to, there have been many problems with USB hubs =
with regard to audio interfaces, and the thing to keep in mind is that a =
USB hub is entirely within the specifications! Using an extender is =
going outside the specifications, so it=E2=80=99s reasonable to expect =
even more problems for audio.

As has been pointed out, USB, USB2, and USB3 each have different cable =
length limits. However, the fact that they are all cross-compatible =
sometimes makes it difficult to know whether you can achieve the longest =
length reliably if both sides are not literally designed to the same =
revision of the specifications.

To your point, though, Dante is rather expensive if you only need to use =
it for one thing. Where Dante starts paying for itself is when you=E2=80=99=
re looking at wiring an entire venue for multichannel sounds with many =
stage boxes, monitors, mixers, computers, and speakers.

Forget about USB, because it was only designed to support short cables. =
If you use a standard that supports Ethernet, you won=E2=80=99t have to =
worry about the length of the cables.
