However, there are differences in the small print: not every switch that supports IGMP snooping can also function as an IGMP querier. The TesiraFORTDAN, based on Audinate's Brooklyn II 32x32 Module,can transmit up to 32channels of audio and receive up to 32 channels of audio using up to 32flows in each direction. The Q-SYS NS Series Gen 2 offers a range of enterprise-grade, NETGEAR-manufactured network switches that have been pre-configured specifically to meet the performance requirements for Q-SYS, AES67 and Dante. Dante Controller Dante certainly works without a DHCP server. When only the primary network is in use the connection status will indicate a green check for the primarynetwork and a circle and slash icon indicating the redundant network is not connected. Multicast flows are encoded at the current setting of the transmit device and will not connect to devices running at a lower bit-depth. Latency can be configured to be different between different devices in the same network, and does not have to be the same for all connections on the network. Non-blocking layer-2 gigabit switch. Device names must be unique on a Dante network. What is Dante? [CDATA[*/(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': Because if there are permanently more than 100Mbit of audio streams, packets are swallowed. Re-apply IGMPsnooping only if it is determined to berequired - it may not be needed. However, if you are building a complex network, a certain reserve is always recommended. If a transmitter runs out of the available flows, use ofmulticast flows may be necessary to reduce the number of transmitted flows. Tesira does not offer 96kHz sample rate support.). Dante offers a full-time redundancy option with permanent primary and secondary audio transmission. Further details on implementing AES67 with Tesira can be found in the article Using AES67 in Tesira. In systems running Tesira firmware 3.15 and higher this message can be disabled to prevent theAIS(Alarm in system) and fault lights indicating an issue when Dante some devices are expected to be disconnected, such as a mixing console or other transitory hardware. While possible in principle, the practical limitations of current wireless technology (802.11a/b/g/n) render reliable performance unachievable. An IGMPquerier IP address must be defined on at least one switch in the Dante network or VLAN. Each Dante channel will have an explicit name. Dante allows you to configure low latency connections for critical audio paths, while at the same time running higher latency connections for a broadcast or recording feed where latency is less critical. A link will always slow down to the lowest speed connector on that link; eg. Most of the time, you do not need to be involved in the Master Clock selection process. In Dante, devices and audio channels are identified by names and labels that can be customized by users. If the Master Clock fails for any reason, a new Master Clock will be chosen from the existing slaves within a few seconds. The DAN-1 card connects via standard CAT-5e or higher network cabling to a network switch. Dante devices can issue IGMP join and leave messages. The numbering of the 2 libraries is unique from one another and uncorrelated. Devices should be updated to Biamp FW 3.11 or later. '&l='+l:'';j.async=true;j.src= Pre-4.2 Dante devices, including Tesira, can participate in domains with Dante 4.2 devices using AES67 or SMPTE. Unless you are using Dante devices that can be daisy chained, you will need a network switch that meets the following requirements to construct a Dante network. For information about fiber media conversion, see Selecting a Fiber Media Converter later in this guide. In this respect, you can't really go wrong. Opinions differ as to which way of working is the better. Follow the sections below to get started. the number of switches, the cable lengths, the desire for redundancy and failure safety. This is likely to be caused by clock configuration errors that result in a loss of synchronization. If you have no experience yet with switches, my recommendation would be either Cisco SG250 or SG350. j=d.createElement(s),dl=l!='dataLayer'? 2. If one or more Tesira Dante channels are disconnected (not routed in Dante Controller) then Tesirasoftware will indicate the system warning "One or more Dante flows inactive." A single DIP switch can be switched to optimize the unit for a Dante network. In event of a failure on one network a redundant device will continue to receive clock synchronization information over the other network. The problem with unmanaged switches: due to the lack of a web interface, no changes can be made to the switch. Once the system has been set up, the Dante Controller software can be shut down or removed. more audio channels that can be transmitted simultaneously, a higher speed at the ports usually also reduces the latency. There are two criteria to look out for: For a few devices or a few Dante channels, ports with 100Mbit/s are sufficient in terms of transmission speed. An extremely high-quality clock is provided by the Tesira backplane, the card bus references that clock for Master Clock duties within the network unless a higher priority clock is available, such as AVB (when present) or Dante. Biamp offers 2 TesiraDante solutions, the DAN-1 card for the Server and Server-IO, and the TesiraFORTDAN models. Devices may not appear in the Routing tab. Tesira 3.8 through 3.10 FW releases updated the Dante cards to the 4.0 Dante FW but Tesirainfrastructure does not yet support Dante Domain Manager (DDM). To create multicast flows the transmitterbit depth must be changed to match that of thereceivers. The Quality of Service (QoS) technology allows the data packets to be prioritized. In this respect, it is understandable that redundant power supplies are rarely found in theater systems at the moment. In this configuration a 3rd party Dante device on the network should be defined as "PreferredMaster". A Dante device with this attribute set will become the PTP Master Clock, unless there is another Dante device present with "Preferred Master" set. "DeviceLockallows you tolockand unlocksupported Dante devices using a 4-digit PIN (Personal Identification Number). When a Tesira configuration is loaded, names are updated on the Dante card. This is an intelligent managed switch that can be used to easily create and monitor a Dante network for touring purposes as well. Channel name changes will be updated in the Tesira configuration file and saved if the file is saved after changes have been made. Products. With the Aruba 2530, for example, VLANs can be set up and the ports assigned via the web browser. Note: A device that has been renamed with (2) appended (e.g. Tesira with AVB and Dante (Tesira file with AVBselected as Network Media clock master): If another Dante device set as a Preferred Master is added to a Tesira Dante system, and that device's Dante MAC address is lower than that of the Tesira Server, it will become the Master Clock device. You can check the number of transmitted flows using the Dante Controller software (under Transmit Flows in the Transmit tab of the Device View). For the connection between different rooms, for example between the FOH and the stage, several networks, i.e. (For 96kHz/24bit audio the channel capacity is halved. EEE reduces device power consumption when network traffic is low. Network switches that satisfy the four requirements listed above will be sufficient for a simple small-scale system, but depending on the system requirements, you may have to take the following items into consideration. e.g. This saves you a lot of work, especially in everyday mobile stage life, because you can not only leave the power supply in the cabinet, but also the power extension and Powercon adapter. Although Dante packet priority values have been chosen to make it simple to configure QoS with many switches, some switches require special configuration to recognize and prioritize specific DSCP values. Setting the Dante blocks to Fixed in unit = True tells the software explicitly which channels in the Dante card you want each block to be assigned to, and locks them there in future recompilations. Because a redundant switch connection is of little use if it is not checked regularly. Once online, channel routing between Dante devices must be done using Dante Controller software. Smaller, Gigabit-only networks can use lower values of latency (down to below 200s). But as soon as you get to the points that are not unimportant for Dante, such as QoS or MSTP, you can no longer continue without the command line. Unicast flows will negotiate the correct bit depth when a connection is made (e.g. The old stage-box is removed, and a new box is plugged in and named stage-box.Dante receivers previously subscribed to the old stage-box will now automatically restore their subscriptions to the new stage-box.. In Dante domains, there is one Grand Master clock, and if the domain spans IPsubnets, an additional 'subnet master' clock for each subnet, plus one or more boundary clocks for each subnet. This will allow both of the DAN-1 cards in the sharedTesira chassis to sync to a common external clock and preclude the possibility of a clock loop. #1:32 input channels to one DAN-1 from (32) 1-channel Dante microphones would be automatically encapsulated within (32)unicast flows containing 1 channel each. Legal characters are A-Z, a-z, 0-9, and '-' (dash or hyphen). To help manage the multicast traffic on the network it is often recommended to enable IGMP snooping on your switches. The beauty of a DHCP server is that you can define a specific address range for the automatic address allocation. And if the active connection fails, the redundant path is automatically activated and the network is fully usable again within a few seconds. Dante wont connect incompatible audio devices. This information includes the quality of its clock, clock source, link speed and other parameters, and results in the best clock being elected as the Master Clock. Since Tesira's clock protocol requires it to be the Master Clock for the system (when AVB is selected as Network Media clock master) this scenario will cause a (major) system fault. The routing information is stored in the Dante-enabled devices themselves. Dante doesn't need special multicast features from switches and is designed to work efficiently with advanced multicast features like IGMP Snooping. Creating a basic Dante network, discovering, and routing signals with Dante Controller, Dante devices, and a network switch. AES67-enabledDante devices support simultaneous use of Dante and AES67flows, even within the same Dante input and output blocks. Biamp strongly recommends always using the latest version of Dante Controller software. This indicates it is aware of another Dante card in the same chassis. A sufficient forwarding rate is 1.4 Mpps per port (gigabit). Always update firmware using Biamp Tesira's software interface or SageVue. Article #1770518 Updated on Sep 21, 2022 at 1:23 PM In this guide, we will explain what Dante is, how it works, and how to get set up and connected for the first time. Setting the Tesirafile to use Dante as the masterin the Media Network settings will allow other Dante devices to be the clock master. . With a primary focus on Q-SYS audio, video & control (AV&C), these network switches provide an out-of-the-box solution for Q-SYS . 1. The TesiraCONNECT TC-5D can have 32 x 32 simultaneous flows, with a total of 32x 32channels. In my opinion, IGMP snooping is absolutely necessary for larger applications and is fortunately supported by most switches. The functions of Dante and QSC Q-SYS devices rely on three key network technologies: Discovery and control (mDNS and known multicast group), QoS (IP DSCP to transmit critical packet, PTP), and Multicast Registration (IGMP for audio streams to join and leave a broadcast). Tesira Dante devicenames may only be changed on an unconfiguredTesira device. /*
