This is the bigger iLive-T112 surface with 28 faders and 4 layers (112 strips) at FOH mix position and the iDR-48 rack on stage near the sources. You get a massive 72 sources to the mix including 48 mics on stage, 16 local line inputs at the surface and 8 stereo internal FX returns. The ACETM digital snake replaces the traditional heavy copper multicore that would be needed with a conventional console. This single CAT5 cable provides the network link for the surface to control the rack and also transports local audio to and from the mix position. Audio available at the rack includes 24 XLR line out, while the surface provides 12 line out (8 TRS, 2 RCA, 1 spdif).
