CobraNet™

Soundweb™ London incorporates the now industry-standard CobraNet™ audio network from Peak Audio, a division of Cirrus Logic, which allows the use of off-the-shelf Ethernet components for building larger systems capable of transferring 32 x 32 channels across a single Cat 5 cable from device to device, many more than were possible with the original Soundweb network. This allows each Soundweb™ London device to create matrix sizes of 40 x 40 channels.

CobraNetSoundweb™ London has also been designed to take full advantage of the latest CobraNet™ features such as low latency settings (as low as 1.33 msec) and 96kHz operation.

BSS has also worked closely with Peak Audio to provide probably the simplest available programming interface to CobraNet™, as well as developing an auto-IP addressing mode that automatically assigns IP addresses to hardware, regardless of existing addresses on the network. Ethernet and CobraNet™ systems have never been this easy to set up.

While some systems rely on multi-way hardware switches for CobraNet bundle assignment, Soundweb™ London can be programmed from directly within the core design software, making the process easier before, at and after installation. Not only can bundles be configured in this way, but also settings can be adjusted in real-time and stored for later recall, and adjusted in real-time.

CobraNetIt can be easy to get lost in the audio interconnection while tracking these bundle assignments, but BSS Audio has taken care of that. CobraNet™ bundles are also referred to within the design software by their user-definable names preventing the need to remember a list of bundle numbers when moving from box to box during the design stage. Additionally when a bundle has been assigned and connected between two devices, an arrow appears over the bundle representation in the design window. Clicking on this arrow will immediately take you to the corresponding CobraNet™ bundle in the other unit.

Network Distances

Soundweb™ London is an Ethernet-based system and as such follows all the same cabling standards as any other ethernet systems. Ethernet allows the maximum of 100 metres between nodes using CAT5 or up to 40 kilometres using single mode fibre-optic connections.


Network Redundancy

CobraNetThe CobraNet™ compatible devices within the Soundweb™ London system are fitted with a Peak Audio CobraNetTM CM-1 module. The module itself offers a Primary and a Secondary CobraNet™ port. Under normal operation the Primary port only receives and transmits audio data from and to to the network. Should the Primary port or connection fail in some way, the CM-1 module automatically switches to receive and transmit audio from and to the Secondary port.
