The SB4 System Bridge from Aviom combines up to 64-channels from four Pro16 or Pro16e A-Net streams onto a single Cat-5 cable, simplifying cabling when using any of the Pro16 series products for personal mixing, digital snakes, or audio distribution systems. All network connections utilize heavy-duty locking Neutrik EtherCon connectors. The SB4 combines up to four 16-channel A-Net streams from digital console cards or analog input modules and transports the data over a single Cat-5 cable. The A-Net Bridge output carries up to 64 channels between the SB4 System Bridge and either another SB4 System Bridge or a D800 A-Net Distributor.

Additionally, many Pro16 products may be connected to a Pro64 A-Net system with the addition of the ASI A-Net Systems Interface. By separating the 64-channel Pro64 stream into up to four 16-channel Pro16 outputs, the ASI translates the Pro64 A-Net data into Pro16 data.
