Studio Technologies Model 5401A Dante Leader Clock

The Model 5401A Dante Leader Clock provides precise timing signals for applications that utilize the Dante® audio-over-IP media networking technology. The unit implements a high-performance IEEE® 1588 precision time protocol (PTP) server, compatible with the requirements of Dante and capable of simultaneously supporting the timing needs of up to hundreds of Dante-compatible devices. As expected, the Model 5401A provides the PTP v1 (IEEE 1588-2002) compatibility that's required by Dante. In addition, the unit supports PTP v2 (IEEE 1588-2008) for AES67 applications. A word clock output provides a general-purpose timing reference for use by external devices. The Model 5401A also generates eight sine-wave audio tones on Dante transmitter (output) channels which can be useful during audio network installation, maintenance, and operation. A sync input connection allows the Model 5401A's internal oscillator to be synchronized with a variety of timing and reference signals.

The Model 5401A is suitable for use in fixed and mobile broadcast facilities, post-production studios, commercial and educational theater environments, and entertainment applications. Only power and one, two, or three Ethernet network connections are required for full operation. Using Dante's inherent capabilities two Model 5401A units can serve in primary and secondary Leader clock roles for redundant operation.

The unit's three Gigabit Ethernet ("GigE") network interfaces can be configured for use in a range of network implementations. For high-performance applications two of the interfaces can support Dante redundancy operation while the third is used for accessing the management webpages. To meet the latest interoperability standard the Model 5401A's Dante implementation supports AES67-2018. The unit also supports the Dante Domain Manager (DDM) software application.

An integrated web server allows fast and flexible monitoring and configuration of the unit's networking, clocking, and Dante performance. Front-panel indicators, an LCD display, and pushbutton switches provide users with direct access to key operating parameters.

The Model 5401A can be powered by 100-240 V, 50/60 Hz mains or a source of 12 volts DC. Both can be simultaneously connected to provide redundant operation. The lightweight enclosure mounts in one space (1U) of a standard 19-inch rack. Industry-standard connectors are used for Ethernet, DC power, and AC mains interconnections. Updating the Model 5401A's operating software can be easily performed using a standard USB flash drive.

Applications

Applications for the Model 5401A include broadcast and post-production facilities, college and university audio networks, arenas, stadiums, and corporate installations — virtually any application where substantial numbers of Dante-compatible devices are utilized. The Model 5401A will serve as a stable and consistent Leader clock for the entire Dante "network." And, as expected, the Model 5401A is compatible with all Dante devices, no matter what their primary function or manufacturer. Applications that utilize devices compatible with AES67 will also benefit from the Model 5401A's resources.
