Check the listing for details. PreSonus NSB 8.8 AVB Networked Stage Box 328 ft. Black. Condition: New. Listed at 599.99 USD. Designed to work seamlessly with PreSonus StudioLive Series III console/recorders, the PreSonus NSB 8.8 is an 8-in, 8-out stage box that sets up quickly and easily to route signals from stage to mixer over an AVB network. With AVB networking, all signals flow through one lightweight CAT5e or CAT6 Ethernet cable, eliminating the need for a heavy, expensive copper snake. An additional benefit of avoiding copper snake is that you avoid signal degradation that is characteristic of such cable runs. You can even remote control the NSB 8.8’s inputs, preamps, and phantom power from your networked Series III console or from free PreSonus UC Surface touch-control software.All inputs can be controlled from a StudioLive Series III console and from free PreSonus UC Surface software.
