Networked Audio System Design with Cobranet™

YAMAHA System Solutions white paper Networked audio system design with CobraNet™

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 compatible 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. The complete package

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.

The first step in any design is to chart the customer’s Based on the system specifications document, basic design The more complex a system the more important design requirements. Sometimes the requirements can be found in options can be conceived. The main decision to make is tools become. A small system can be described in words or a formal tender if a consultant has already been involved the selection of the technology to be used: analogue or an excel sheet, but larger or more complex systems have to in the customer’s system specification process. In many digital, point to point or networked, closed (proprietary) be described in drawings to be able to communicate them cases the consultant or system integrator has to discuss or open (manufacturer-independent) platforms etc. These to all stakeholders in a project. In these cases software the customer’s requirements in depth to find the most decisions are fundamental as they determine the degree of programs are used to construct system designs, such as appropriate system specifications, and perhaps suggest freedom allowed in further design stages. AutoCAD in the contracting business, StarDraw in the additional system possibilities made possible by new audio markets and CobraCAD for CobraNet™ system technologies on the market. Selection of network and audio devices designs.

System specifications After the technology platforms have been selected the System test system’s actual network and audio devices must be The second step is to draw up a system specification based selected. Input parameters for selection include feature A very important part of the network design process on the customer’s requirements. A system specification set, audio quality, technical reliability, supplier reliability, is to conduct (sub) system tests. Especially network document contains the requirements for a system to fulfill complexity and of course cost level. There are no products systems using managed switches offer an extremely high as operational parameters. The system specifications with an ‘A-score’ on all of these parameters; quality comes functionality level that require system tests to verify that should not include any direction to actual solutions as that with higher costs, more functionality comes with a more all parameters have been programmed correctly. would narrow the scope of possibilities in the design stage. complex user interface, etc. The designer must study each Only by keeping the system specifications and the design system component’s feature set in depth to assess if it meets Training & after sales solution options strictly separated can the broad scope of the system specifications or not, and conceive creative choices be truly considered by the designer, allowing for solutions in case no matching products are available. A networked audio system offers different functionality maximum flexibility, quality and creativity in the design compared to analogue systems. Therefore the design of stage. appropriate after sales and training activities for future users of the system is an important part of the design stage. 2. Specification list for Yamaha System Solutions CobraNet™ designs

Based on the customer’s requirements a system Cabling Latency specification must be drawn up. For this white paper a ‘one size fits all’ system specification is listed intended The design concept should cover long distance cabling of The network should support a fixed latency of 1.3 ms for to cover most of ‘every day’ applications from small up to 500 meters. The network design should support up mid size systems. For larger systems higher fixed latency touring sound reinforcement sets to large scale distributed to five long distance locations. The long distance locations modes are allowed. i/o installations.

System CobraNet™ IP over Ethernet

All four rooms offer connectivity to four analogue stereo Each room features one DME8i-C and one DME8o-C A computer can be used to control the DME units in the player/recorder devices such as compact cassette, CD, device offering 8 inputs and 8 outputs in all rooms. Each system with user friendly control menus on the computer’s DVD, Minidisk etc. Two faders and on/off switches with DME8i-C unit transmits one multicast bundle so all inputs display. GPI functionality of each DME device in the tally LED are provided in all four rooms for simple control of all rooms are available in any location. For ad-hoc system can be linked to all other DME devices for detailed of the audio level. Further GPI inputs and outputs are expansion a mixing console or extra i/o devices can be control of the complete system functionality. Each room is available to control external equipment. More detailed connected to any switch in the system, e.g. when two or fitted with an IP camera offering simple and cost effective control of the audio functionality can be realized using a more rooms are combined for a company presentation an video links between rooms using computers connected to computer with DME designer user control displays on a 01V96 mixing console can be used to mix the event. the control network. As the DME designer software offers computer display. Crestron® or AMX™ Control systems easy interfacing functions for Crestron® and AMX™ can also be used, integrating other multimedia devices in systems, the audio system can be integrated in total the system such as video recorders, projectors etc. multimedia systems based on these platforms.
