Dante Times Are Coming, Are You Ready?

Hello everyone, today is Monday. I'm your editor. Every Monday is the new beginning of a week. Since it's the new beginning, the editor will take you to know Dante who we chased together in those years.

Do you know Dante? Do you know Dante? Are you interested in him? Do you know his importance in the audio industry? If you don't know, don't understand, it doesn't matter. Xiaobian will answer for you that "Shenma" is Dante, Dante has the advantages and uses of "Shenma".

A: what is the Dante agreement?

B: Dante protocol is a modern high-performance digital media transmission system running on a standard IP network. That is to say, it is a technology of transmitting real-time audio signal in Ethernet with IP data structure, which provides a low delay, high precision and low cost solution for point-to-point audio system connection. It was developed by audinate in 2003. Like the traditional CobraNet technology, it is also a product integrating hardware, software and communication protocol.

A: what are Dante's advantages?

B: Dante technology allows many audio channels to be sent and received simultaneously on one Ethernet cable, and avoids the complexity and limitations of earlier solutions. Dante's low latency and strict synchronous playback can meet the requirements of the most demanding audio system, and its compatibility with existing IT equipment is very good. The difference between Dante and traditional products is that Dante has already crossed the two-tier network communication protocol, completely adopted the more advanced and convenient IP three-tier communication protocol, and can directly transition to the AVB (audiovideo bridging) protocol through the fixed upgrade, which is a very important step.

A: how many audio channels does Dante protocol support?

B: Gigabit Network: support 512 * 512 48Khz / 24bit audio channels on a single link, that is, a total of 1024 bidirectional channels. For 96KHz / 24bit audio data stream, the channel capacity is halved.

100m network: support 48 * 48 48Khz / 24bit audio channels on a single link, that is, 96 bidirectional channels in total. For 96KHz / 24bit audio data stream, the channel capacity is halved.

Dante protocol supports 48Khz and 96KHz audio sampling rates. The sampling rates supported by products from different manufacturers are different.

A: when Dante is used, what is the minimum delay of two audio nodes in the network?

B: in principle, two audio contacts are directly connected by gigabit network, and the network is perfect. When a single audio data is collected and transmitted through its own IP packet, Dante's measured delay is the same as the standard of gigabit network, both of which are 83.3 μ s.

A: performance comparison between Dante and ethersound

B: Dante has no topology limitation and installation complexity; Dante protocol supports a maximum sampling rate of 192Khz, a maximum of 1024 channels of bidirectional transmission on a single link, with a minimum delay of 83.3 μ s, while ethersound protocol only supports a maximum sampling rate of 96KHz, a maximum of 512 channels on a single link, and audio data flow can only pass through hub or switch in one direction, with a minimum delay of 83.3 μ s The delay is 125 μ s, so Dante outperforms ethersound in performance. And Dante can provide fault backup, which is a very obvious advantage for field activities.

A: performance comparison between Dante and CobraNet

B: CobraNet protocol is a network audio transmission technology developed by peakaudio company in 1996. So far, CobraNet is widely recognized as the "ancestor" of all networked audio technologies. It is regarded as an effective audio protocol and will continue to serve the industry well. Although supported by more than 50 CobraNet product manufacturers, CobraNet has not become the industry standard.

CobraNet protocol supports up to 96KHz sampling rate, 128 bidirectional audio channels on a single link, and does not support routing, with a minimum delay of 1 / 3MS. Compared with Dante protocol, these data performance is worse. And CobraNet protocol has no fault backup.

A: a simple Dante audio transmission network system

B: the simplest audio network system of media matrix is to connect one RJ-45 network cable to two media matrices (model with n), with a distance of up to 300m / 1000ft. Allows audio signals of 16 channels to be transmitted in two devices. The transmission path is completed by the audio system design engineer. And the control function can be every [sensitive word] vertical control, of course, you can also control the parameters in another media matrix through the network path, for example, the delay with one device can also be used to control the output delay of the mixer on another device. And the computer can insert any loading program and adjust the parameters of two devices.

A: how to deploy Dante in the conference system?

B: the meeting solution of the main and sub venues is a new solution for our modern interconnection trend. Because there are not many functional requirements for the sub venues, minimalism and practicability are its main requirements. It can be seen that the sub venues do not have different types of lines except for the network lines, and all the equipment processes and transmits signals through switches. Large It is easy to arrange the venue, and it also saves the trouble of arranging the circuit. The personnel only need to put the audio equipment in the corresponding position. It is very suitable for the temporary arrangement of meeting places.
