Dante Bridge for Network Interconnection

Audio professionals have adopted the Dante Audio-over-Ethernet (AoE) protocol as a “go to” method of interconnecting devices using standard Ethernet networks. Dante’s audio quality, flexible features, and simple deployment has encouraged broad adoption among equipment manufacturers. Despite these strengths, interoperability between networks can prove challenging. Studio Technologies, manufacturer of audio, video, and fiber-optic solutions, has announced a simple, yet high performance solution with the Model 5482 Dante Bridge. The unit provides a means of “bridging” up to 64 AoE channels between LANs or Dante domains.

Each of the Model 5482’s independent interfaces provide three Gigabit Ethernet network ports, allowing support for both switched and redundant Dante operation along with a separate management network connection. Each “side” of a Model 5482 can be independently configured to match the unique demands of an application. The unit allows up to 64 audio channels to pass in each direction with support for up to 24 bits at 44.1, 48, and 96 kHz sampling rates. Sample-rate-conversion (SRC) capability, implemented in high-speed programmable logic, ensures that audio signals with different sampling rates and timing references can be directly interconnected.

The Model 5482 is compliant with the AES67 standard and supports the Dante Domain Manager (DDM) software application. Each of the unit’s Dante interfaces can function independently — for example one of the network interfaces can be operated through DDM while the other remains “open.” Each interface can be configured to support AES67 digital audio signals, allowing the Model 5482 to serve as a unique Dante-to-AES67 bridge.

The 1RU unit’s front panel features a user-friendly interface with LED indicator lights, a graphics display, and push-button switches to observe and configure key operating parameters. Operating power can be provided by 100-240 volts, 50/60 Hz, or a source of 10-18 volts DC. If both AC and DC power are connected, then the Model 5482 will be powered by the AC mains source with DC serving as a “hot” standby.
