Studio Technologies Unveils Model 5401

Studio Technologies has announced details of the Model 5401 Dante Master Clock. The Model 5401 provides precise timing signals for applications that use Dante Audio-over-Ethernet media networking technology

The unit implements an 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.

The Model 5401 provides the PTP v1 compatibility required by Dante, as well as supporting PTP v2 for AES67 applications. The unit also generates up to eight sine-wave audio tones on Dante transmit (output) channels. A clock input connection enables the Model 5401 to synchronise with a variety of timing reference signals. It can also be locked to a variety of external signals for integration into facilities that include a master timing reference. Compatible signals include word clock, video sync, and 10 MHz sine-wave.

Word clock, typically 48 kHz, is often used in audio-only facilities and is compatible with the Model 5401's sync input. Video reference (sync) signals are found in broadcast, post-production, and entertainment facilities. The Model 5401 supports the most-common video format/rate combinations including black burst, bi- and tri-level HD, and several that are specific for 4K applications. Industrial and commercial facilities often deploy a GPS-disciplined source of 10 MHz as a timing reference. This sine-wave signal is directly compatible with the unit's sync input.

The Model 5401 is capable of generating eight separate sine-wave tones, each configurable in level and frequency. The tones are digitally-generated in hardware that is separate from that associated with the unit's PTP functionality. This allows the Model 5401 to perform its timing tasks without risk of interruption due to conflicting resource demands.

Dual Gigabit Ethernet (GigE) network interfaces allow the Model 5401 to support switched, redundant, and split Dante operation. An integral Web server allows monitoring and configuration of the unit's clock, audio tone, and general Dante performance. Front-panel indicators, LCD display, and pushbutton switches provide personnel with direct access to key operating parameters. The Model 5401 can be powered by AC mains or12 volt DC.

When both are connected, redundant power operation is supported. It mounts in 1U of a standard 19-inch rack.

Gordon Kapes, president of Studio Technologies, said: "With Dante becoming ubiquitous in fixed and mobile facilities of all sizes and types, we saw the need for a cost-effective, purpose-designed, dedicated master clock. While an inherent strength of Dante networking is its carefully implemented use of IEEE 1588 to ensure that all connected devices maintain a common timing reference, the actual performance can vary widely depending on the specific Dante devices in use and the overall number of devices on a network. There are many Dante-compatible devices that can provide adequate basic performance as a master clock, but with the Model 5401, networked audio systems get the benefits of a high-performance grandmaster PTP server, along with additional unique capabilities. The feature set, along with the associated internal hardware and software, were designed to provide optimum performance, flexibility, and system integrity."
