Provide your Dante-equipped gear with precise timing signals with the Studio Technologies Model 5402 Dante Leader Clock, a 1 RU device that utilizes a high-performance IEEE 1588 PTP server for supporting the timing needs of up to hundreds of Dante-compatible devices. With the integrated GNSS receiver, timing reference can be derived from GPS, Galileo, BeiDou, and GLONASS.
The Model 5402 provides compatibility with PTPv1 and PTPv2 for AES67 and ST 2110-30 applications. BNC connections are available for precision Word Clock output and sync input. Three Gigabit RJ45 ports are provided, with two dedicated to Dante and one designed for web interface management. These ports can be reconfigured via several modes for different applications. The unit also offers eight audio tone signals for testing. With redundant power options, you can keep your unit connected to both mains AC and 10 to 18 VDC power (via XLR 4-pin), ensuring that your backup DC power source will seamlessly take over should your primary mains power source fail. The Model 5402 includes a high-precision multiband antenna.
And, as expected, the Model 5402 is compatible with all Dante devices, no matter what their function or whom their manufacturer. Applications that utilize devices compatible with AES67 and ST 2110-30 will also benefit from the Model 5402's resources.
There are many Dante-compatible devices that can provide adequate basic performance as a Leader Clock, but with the Model 5402 networked audio systems get the benefits of a high-performance primary Leader Clock, along with additional unique capabilities. The unit's feature set, along with the associated internal hardware and software, is designed to provide optimum performance, flexibility, and system integrity.
- The Model 5402 can provide excellent Leader Clock performance using a timing reference that is based on signals provided by one or more GNSS (satellite) constellations.
- This will ensure accuracy and stability that exceeds the capability of standard Dante devices by at least an order of magnitude.
- A configuration choice is provided in a Model 5402 webpage to allow a failover source of timing to be selected should a valid GNSS signal become unavailable.
- The Model 5402 will also provide strong Leader Clock performance using its temperature-stabilized internal oscillator.
- While its standalone performance is excellent, it can also be locked to a variety of external signals for integration into facilities that already include a central or main timing reference.
- Compatible signals include word clock, video reference, and 10 MHz. Word clock is a square wave signal that is often used as a timing reference in audio-only facilities.
- Video reference (sync) signals are found in most broadcast and postproduction facilities.
- The Model 5402 supports the most-common video format/rate combinations including black burst, bi- and tri-level HD, and several that are specifically intended for 4K applications.
- Industrial and commercial facilities often utilize a source of 10 MHz sine wave as a timing reference.
In addition, the unit allows augmentation support for GPS as provided by QZSS (Japan). Configuration choices allow which constellations will be utilized by the Model 5402. This can range from one to all four constellations. Using these capabilities, the Model 5402 can achieve single-digit nanosecond timing accuracy. Multiple, geographically dispersed sites (network nodes) can each use a Model 5402 to easily achieve a coordinated timing reference.
The word clock output rate can be 44.1, 48, 88.2, 96, 176.4, or 192 kHz. The underlying timing source for the word clock output is derived from the Model 5402's main timing source. This will typically be one or more of the supported GNSS constellations. The main timing source is divided and processed by the Model 5402's logic circuitry to create the highly stable word clock output. This ensures that the word clock output is synchronized with the unit's PTPv1 and PTPv2 server functionality.
The flexibility of being able to interconnect signals (create Dante subscriptions) between all Dante devices on a network allows the audio tones to be used for a variety of purposes. Configuration choices allow the frequency and level of each sine wave tone to be optimized for use in specific applications.
- In the Switched mode, a single Ethernet connection to either of the Model 5402's two Dante Ethernet ports will provide Dante Leader Clock functionality. The remaining Dante Ethernet port will provide Dante network loop-through capability and can be used to interface with another piece of Ethernet-connected equipment. The management Ethernet port will be used to access the Model 5402's monitoring and configuration webpages.
- In the Redundant mode, two independent Ethernet connections are made to the Model 5402's two Dante Ethernet ports, enabling Dante's redundant networking capability. Again, the management Ethernet port will be used to access the Model 5402's monitoring and configuration webpages.
- In the Switched+Mgmt mode, a single Ethernet connection is used for both Dante Leader Clock functionality as well as providing access to the Model 5402's management web pages. The remaining Dante Ethernet port will provide network loop-through capability and can be used to interface with another piece of Ethernet-connected equipment.
Only if the AC mains source fails will appreciable power be drawn from the DC source. This allows a source of DC, typically an external power supply, to serve in a backup capacity. With this arrangement normal operation can continue, even if AC mains power is lost.
