The Soundcraft® Vi BLU Link card is a 32 x 32 interface between a Vi series console and the Soundweb London digital audio bus, informally known as BLU Link. The card allows connection to a wide variety of Harman products equipped with a BLU Link interface, such as BSS London BLU 800, dbx® PMC or Crown® PIP-BLU interfaces amongst others. BLU Link is a low latency, fault tolerant digital audio bus of 256 channels which gives a distance of 100m between compatible BLU Link enabled devices using standard CAT5e cabling. To increase the distance between devices the BSS Audio MC-1 fibre optic media converter can be used to span over 10km (6.2 miles) using single mode fibre.
