N8 is an advanced audio distribution hub that uses Cranborne Audio’s C.A.S.T. system to transform network cable (Cat 5e, Cat 6, or Cat 7) into 4-channel analogue snakes and breakout boxes that can be routed around the studio or stage.
Set N8 in your control room and patch directly to the IO of your audio interface via DB25. N8 then converts analogue IO from the audio interface into 4 discrete C.A.S.T. connections that can be distributed to C.A.S.T. breakout boxes such as N22 and N22H in your studio or on the stage.
In a real-world example, a vocal booth created with XLRs, would require 2 XLR cables for microphones, 2 more XLR cables for a stereo monitor mix for the singer, and a headphone amp with power. And after that, unless you're handy with a soldering iron, you'll be left with trailing XLRs and no discrete box to patch to.
N8 and C.A.S.T. replaces all of that complexity with one networking cable and neat, compact breakout boxes over distances up to 100m (330ft).
