About Dante Overview This product features Dante technology as a protocol to transmit audio signals. Dante is a network protocol developed by Audinate. It is designed to deliver multichannel audio signals at various sampling and bit rates, as well as device control signals over a Giga-bit Ethernet (GbE) network. Dante also offers the following benefits: • It transmits up to 512 in/512 out, for a maximum total of 1024 audio channels over a GbE network. (The NUAGE I/O series can be accommodate up to eight devices, 128 in/128 out with a 24-bit resolution on a NUAGE system.) • Dante-enabled devices will automatically configure their network interfaces and find each other on the network. You can label Dante devices and their audio channels with names that make sense to you. • Dante uses high accuracy network synchronization standards to achieve sample-accurate playback with extremely low latency and jitter. • Dante supports redundant connections via primary and secondary circuits to defend against unforeseen difficulties. By taking advantages of these benefits, you can skip any complicated procedures to automate connections and setups of Dante-enabled devices, remotely control I/O racks or amplifiers from a mixing console, or make multitrack recordings to a DAW, such as Nuendo, installed on a computer in the network.

Star Connection In a star connection, each device is connected to a central network switch. Using a GbE-compatible network switch enables you to configure a wide-band, large-scale network. We recommend a network switch that features various functions to control and monitor the network (such as Qos, the ability to assign priority to data flows - e.g., clock synchronization or audio transmission on certain data circuits.) With this topology, it is common to configure a redundant network so that an unexpected network problem will not affect any audio or otherwise stable communications. About Dante Redundant Network A redundant network consists of two circuits, a primary circuit and a secondary circuit. Normally, the network operates on the primary circuit. However, if the primary connection is broken, the secondary circuit will automatically take over communications. Therefore, using a redundant network with a star topology would increase communication stability relative to a daisy chain network.

This connection method is suitable for a simple system with a small number of devices. However, if a large number of devices are connected, the latency value must be increased. Also, if a connection is broken in a daisy chain network, the signal flow is interrupted at that point and no signal will be transferred beyond that point.
