Got this for my X32 Rack to Connect with SD8. Great solid Built of a cable! but...
First of all, if you're planning to hook up your SD8/S16 in the same rack as your X32 Rack then this will probably be a great idea.
However i now place my SD8 in the opposite side of the stage as it reduces alot of cables running around stage,
So i have a stage box on both ends of the stage and im lovin it!
Anyhow, why i say its not entirely neccesary is because you can actually just use a Cat6 Cable, however im keeping this cable just incase my cat6 Cable goes bad on me.
