The Model 5482 Dante Bridge provides a high-performance means of interconnecting ("bridging") Danter audio-over-Ethernet channels associated with two independent local-area-networks (LANs) or Dante domains. The unit is compatible with the Dante Domain ManagerT (DDM) software application and is complaint with the AES67 technical standard. The Model 5482 is available in two versions: the Model 5482-01 allows up to 32 audio channels to pass in each direction, while the Model 5482-02 allows up to 64 audio channels. Internal sample rate conversion (SRC) capability provides sample rate, bit-depth, and timing conversion to ensure that audio signal integrity is maintained.
Dante audio-over-Ethernet has found wide acceptance as a network "backbone" due to its ease of use, excellent audio performance, strong interoperability, and wide adoption by a large number of equipment manufacturers. However, interconnecting Dante audio channels on independent local-area-networks or domains can present a challenge. But using the Model 5482 makes this a simple task, only requiring interconnecting standard Ethernet signals and performing a minimal amount of configuration. A few minutes of time is all that's required to make the unit part of a sophisticated, networked audio system.
The Model 5482 can be powered by 100-240 V, 50/60 Hz or a source of 12 volts DC. Both can be simultaneously connected to provide redundant power operation. The unit's lightweight enclosure mounts in one space (1U) of a standard 19-inch equipment rack. Industry-standard connectors are used for the Ethernet, AC mains, and DC power interconnections. The unit is built to professional standards and is intended for continuous, 24-hour operation.
Each of the Model 5482's two Dante interfaces incorporates three Gigabit Ethernet (GigE) connections. Two GigE ports are designated for use by the associated Dante network while the third is reserved for factory configuration use. A setting performed within the Dante Controller application selects whether each Dante interface will operate in a Switched or Redundant mode. For installation flexibility the two Dante interfaces can be configured independently.
Front-panel LED indicators, an LCD display, and five pushbutton switches are provided to view and revise selected operating parameters. The Dante Controller software application, available free of charge from Audinate, is used to configure all Dante network and audio parameters.
Dante Audio-over-Ethernet
Audio data is sent to and received from each Model 5482 interface using the Dante audio-over-Ethernet media networking technology. Two separate network interfaces allow completely independent Dante configurations. Audio signals with a sample rate of 44.1, 48, 88.2, and 96 kHz and a bit depth of up to 24 are supported.
A special function allows, if desired, the timing reference from one interface to be used as the reference timing for the Leader Clock on the other. This will result in the Dante synchronization on one LAN to be utilized as the synchronization source on the other.
