Merger hub is similar to familiar Ethernet switch but with features and performance designed specifically for use in real-time streaming audio applications. It provides way to build Pro64 digital snake or audio network with parallel connections without sacrificing ability to distribute signals bi-directionally throughout an installation. It features same basic functionality as MH10 merger hub, but replaces ports 9 and 10 with 100Mbps fast Ethernet SFP slots which can be outfitted with either single- or multi-mode SFP fiber optic transceivers. It can be combined in Pro64 network with MH10 merger hubs as needed. It merges inputs from all ten ports, ensuring that all 64 active channels in network are distributed back out all ten ports, regardless of physical location of those inputs. Those 64 channels can be physically located off any combination of the ten ports, even if they go through multiple MH10 or MH10f hubs.
