The Holy Grail of audio distribution, unlimited zones and unlimited sources, cost-effectiveness. This milestone will be reached, and sometimes a combination of marketing and distribution of digital IP-based systems. There are systems available today that use one or both of these technologies, such as the Sun and Oxmoor Netlink 'NetStreams products. The trend only continues to grow.
The beauty of this method is that digitalThe music is given, and as such can easily spread via an Ethernet network. The traditional concept of zones virtually disappears, as each amplifier on the network have a unique IP address so that an audio stream to run into. In combination with a digital music server, the number of sectors that the capacity of the server that only serve independent audio streams.
The advent of cost effective digital amplification, as companies likeas D2 Audio and Flying Mole, a small audio amplifier with high efficiency to approach the speakers are located in space or mounted in an electric field. Logical development of this strategy is to put the amplifier with the speaker, creating an active speaker. Further advantages are achieved by integrating speaker as part of the cycle. This allows the designer of a system to ensure the speaker and amplifier circuits for optimum performance.
Low powerdesign of this type using the power Ethernet (POE), simplifying system wiring by allowing a CAT-5 cable from the router to the speaker. It would be a great amount of power (15 watts) due to limitations of 24ga wire CAT-5. But efficiency is obtained by an integrated speaker / amplifier that question to a lesser extent. This type of system is sufficient for background musicapplications in many quarters.
higher power systems can use the existing speaker wire, in case of a conventional wire, carry the power. It may / may not be cable to the existing control, since many systems are wired with CAT-5 position of the volume of data.
The bandwidth of a traditional 10/100 network allow, in effect, an unlimited number of zones and sources in a residential area. PartialFor this reason, and audio over Ethernet is used successfully in the reinforcement and commercial audio sound in the world for a number of years. By Cirrus Logic CobraNet is the most popular trading system used today AOE. Another popular system is available from Digigram. These systems use both the Ethernet MAC layer and are not actually using IP for transmission.
For both residential and commercial property claims second major advantage of using Ethernetis the ability to use the medium to transport audio and control signals from the same thread. This increases costs and reduces flexibility both for installation and materials.
If it was right in the commercial world, the distribution of audio (and soon video) and control using Ethernet will continue to distribute all residential audio applications. The combination of flexibility, cost effectiveness and ability is attractive to be ignored.
