COMMENTARY SYSTEM
Audio Matrix: Networking Without Frontiers
The product range includes oratis matrix frames of various sizes. One distinctive feature is the high packing density: Up to 15 oratis cards per 4-U matrix frame is achievable. Thus, oratis systems are a logical choice whenever every inch counts – for example, in an OB truck.
System Expansion
Each matrix frame holds up twelve oratis IF LAN cards, each connecting one commentator terminal. The IF LAN cards can be combined with audio interface cards and can be supplemented with intercom and GPI cards used for controlling external devices. oratis matrix frames include a line-ident memory used for loop-playing up to 24 idents. This enables the various stations‘ live studio lines to be identified uniquely. As soon as the commentator goes on-air, the line ident is automatically muted.

Large systems supporting more than 500 commentator terminals are created by interconnecting multiple matrix frames. The matrix frames are networked using fibre-optic cabling, which is also used for clock distribution all over the system. The network employs the Gigabit Ethernet layer-2 protocol. This protocol allows for direct connections between matrix frames as well as for networking using managed Gigabit Ethernet switches.
