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 PTPv1 (IEEE 1588-2002) compatibility that's required by Dante. In addition, the unit supports PTPv2 (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 and data 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.
