This white paper’s subject is Networked audio system design with CobraNet™.
The design concept in this paper supports systems varying from small touring event setups to very large scale networked audio installations. That does not mean that the design concept is the best solution to all system specifications, other network topologies and audio protocols should always be considered in the initial phase of the design project. The advantage of this Yamaha System Solutions design concept is that it is based on Ethernet / CobraNet™, both open protocols that use computer networking components widely available on the market. Other compat-ible brands of both network and audio equipment can be included in the design concept, assuring maximum flexibility and project efficiency for system integrators. It is also good to know that the design concept is not just a theoretical exercise; we have built, tested and installed systems based on this design concept so you can be confident that the concept will work in real life.
We assume the reader is a system integrator with detailed knowledge of analogue and digital audio, and basic knowledge of networking technologies as covered in the ‘Yamaha System Solutions - an introduction to networked audio’ white paper.

1. System designCustomer’s requirements
The first step in any design is to chart the customer’srequirements.Sometimestherequirementscanbefoundinaformaltenderifaconsultanthasalreadybeeninvolvedin the customer’s system specification process. Inmanycases the consultant or system integrator has to discussthe customer’s requirements in depth to find the mostappropriate system specifications, and perhaps suggestadditional system possibilities made possible by new technologiesonthemarket.
System specifications
Thesecondstepistodrawupasystemspecificationbasedon the customer’s requirements. A system specificationdocumentcontainstherequirementsforasystemtofulfillas operational parameters. The system specificationsshouldnotincludeanydirectiontoactualsolutionsasthatwouldnarrowthescopeofpossibilitiesinthedesignstage.Onlybykeepingthesystemspecificationsandthedesignsolutionoptionsstrictlyseparatedcanthebroadscopeofchoicesbetrulyconsideredbythedesigner,allowingformaximumflexibility,qualityandcreativity in thedesignstage.
Design options
Basedonthesystemspecificationsdocument,basicdesignoptionscanbeconceived.Themaindecision tomake isthe selection of the technology to be used: analogue ordigital,point topointornetworked,closed (proprietary) oropen(manufacturer-independent)platformsetc. Thesedecisionsarefundamentalastheydeterminethedegreeoffreedomallowedinfurtherdesignstages.
Selection of network and audio devices
After the technology platforms have been selected thesystem’s actual network and audio devices must beselected. Input parameters for selection include featureset,audioquality,technicalreliability,supplierreliability,complexityandofcoursecostlevel.Therearenoproductswithan‘A-score’onalloftheseparameters;qualitycomeswithhighercosts,morefunctionalitycomeswithamorecomplexuserinterface,etc.Thedesignermuststudyeachsystemcomponent’sfeaturesetindepthtoassessifitmeetsthe system specifications or not, and conceive creativesolutionsincasenomatchingproductsareavailable.
Design tools
Themore complex a system themore important designtools become. A small system can be described in words or anexcelsheet,butlargerormorecomplexsystemshavetobedescribedindrawingstobeabletocommunicatethemto all stakeholders in a project. In these cases softwareprograms are used to construct system designs, such asAutoCAD in the contracting business, StarDraw in theaudio markets and CobraCAD for CobraNet™ systemdesigns.
System test
A very important part of the network design processis to conduct (sub) system tests. Especially networksystemsusingmanagedswitchesofferanextremelyhighfunctionalitylevelthatrequiresystemteststoverifythatallparametershavebeenprogrammedcorrectly.
Training & after sales
A networked audio system offers different functionalitycompared to analogue systems. Therefore the design ofappropriate after sales and training activities for futureusers of the system is an important part of the designstage.
2. Specification list for Yamaha System Solutions CobraNet™ designsBased on the customer’s requirements a systemspecification must be drawn up. For this white paper a‘one size fits all’ system specification is listed intendedto cover most of ‘every day’ applications from smalltouringsoundreinforcementsetstolargescaledistributedi/o installations. Although this system specification listwillmost probably produce a system design thatmeetsthe average customer’s requirements, it might covermore than required.To achieve efficient systemdesignsit is recommended to carefully go through the first stepof the systemdesign process of charting the customer’srequirementsbeforedrawingup thesystemspecificationlist.
True Network
Thedesignconceptshouldcovervirtuallyallapplicationsizes; from simple P2P connections to large scaleinstallations with many locations. To allow this levelof scalability, and to keep systems manageable, a truenetworkprotocolshouldbeused.Functionalconnectionsmustbeseparatefromthephysicalcablinginthenetworkassumingthenetworkofferssufficientbandwidthfortheapplication.

3. Network & Redundancy conceptBased on the system specification list in the previouschapter the followingYamaha System Solutions designconcept is proposed.
Network
The Yamaha System Solutions design concept usesCobraNet™audiodevices.All devices are connected toa Gigabit Ethernet network using a star topology. Thenetwork uses managed switches supporting VLAN andRapidSpanningTreeProtocols.
VLAN
ThenetworkisdividedintwoVLANs:oneforCobraNet™andoneforcontrol.Ifasystemrequirestheuseofmanymulticastbundles,additionalVLANscanbeincluded.
Switches
A high capacity and a low capacity switch supportingGigabitconnectivityareusedtobuildthenetwork.
Bothswitchessupport IEEE802.1qVLAN,IEEE802.1wrapid spanning tree, IEEE802.3ad link aggregation andQoSfunctionality.
Star locations
AhighcapacityswitchincludingatleastfourGBICportsforGigabitfiberconnectivityisusedforthestarlocation.Such a high capacity switch is typically not availablewithoutcoolingfans,sothislocationshouldbeplannedinaplacewhereacousticnoiseisnotaproblemsuchastheamplifierrack.

Cabling
Alllongdistancecablingfromthestartothefourlocationscarrying Gigabit network information is specified with50 µmmultimodefiber,connected to theswitchesusingappropriateGBICfibermodules.Fordistancesunder50metersCAT5Ecablingcanbeusedinstead.
All further connections in the systemuseCAT5cablingcarrying100Mbnetworkinformation.
Redundancy
All locations use double switches, labelled primary andsecondary, with aGigabit link between them.The twoswitchesareconnectedtothestarlocationbytwocables,preferably laidoutoverdifferentphysicalpaths throughthe venue. All CobraNet™ devices’ primary links areconnectedtotheprimaryswitch,andthesecondarylinksto thesecondaryswitch. In thestar location’ssecondaryswitchtheRapidSpanningTreeProtocolisactive.

Checklist
After assembling a networked audio system it is goodpracticetoconductasystematicseriesofcheckstomakesure everything is OK. These checks should includenetwork functionality, audio functionality and sabotagebehavior.
Check 1: Double check network settings
Connect a PC to the default VLAN and confirm thatall switches are on-line, for example Dlink’s D-Viewmonitoring software. Double check the VLAN settingsandSTPsettingsineveryindividualswitchbybrowsingthemonebyone.
Check 2: Check the CobraNet™ network
Connect a PC to the CobraNet™ VLAN and launchCobraNet™Manager.ConfirmthatallCobraNet™devicesareshownintheoverview.
Check 3: Double check audio settings
Using the appropriate software, double check the audiosettings in all individual CobraNet™ devices: bundlenumbers, wordclock settings, sample size and latencymode. Confirm that the conductor is assigned to theappropriatedevice.
Check 4: Listen
Connect some small speakers to the most importantsystemoutputsandthenconnectanaudiosourcetoeveryinputone-by-oneandcheckifaconnectiontotheoutputsisavailablewithgoodsoundquality.
Check 5: Disco
Connect a PC to the CobraNet™ network and launchDiscoverytoconfirmthatallaudioconnectionsarereallyerror-free.Checkforerrorsatallbundles.
Check 6: Sabotage
Sabotage all network components in the system one byone: remove cables or power down switches, confirmsystem recovery, re-connect or power-up, confirm thatthe system switches back to a redundant state.Note therecovery timing at each stage to include in the projectdocumentation.
