The N8 is an advanced audio distribution hub that uses Cranborne Audio's C.A.S.T. system to send 4-channel audio via Cat 5e, Cat 6 or Cat 7, up to 100m. Set up the N8 in your control room and patch directly to the i/o on your sound card. The N8 then converts the signal from the sound card to 4 discrete C.A.S.T. outputs that can be distributed to C.A.S.T. breakout boxes like the N22 and N22H in your studio or on stage.
