19-Nov-2018 Dante ST 2110

New Product Audio Performance – A Big “Thumbs Up”

Last month we took final prototypes of our new Model 5512 Audio Interface and Model 5518 Mic/Line Interface units for a “real-world test drive” at a well-regarded music recording studio in Chicago. The ‘5512 and ‘5518 support SMPTE ST 2110 and utilize our latest analog and digital circuit designs. These units are hardware “cousins” with the new Dante-enabled Model 5412 Audio Interface and Model 5418 Mic/Line Interface. We knew that the performance specifications of all the units as measured by our test equipment was very good.

Supporting PTP v2 (AES67 and ST 2110) with the Model 5401

Updated 21-Dec-2020

The Model 5401 Dante Master Clock was initially designed for use in applications that utilized devices running “native” Dante. To support the master timing needs of these devices Precision Time Protocol Version 1 (IEEE-1588-2002 or “PTP v1”) was implemented. The unit’s PTP v1 implementation functions very well, including in redundant Dante applications. (Independent Ethernet networks connected to the Primary and Secondary Ethernet ports on the back panel of the Model 5401.) Even in large installations with literally hundreds of Dante devices,

Configuring Ethernet Switches for Audio-over-Ethernet Use

This document from Lawo regarding setting Ethernet switch parameters for optimizing audio-over-IP operation is really terrific:

https://www.lawo.com/support/know-how/ip-networking-guide/specific-switch-configurations.html

We implemented the suggested settings on an SG300 and it allowed much-improved performance when testing our new ST 2110-compliant products. We had been told that only “PTP aware” Ethernet switches were acceptable for use with ST 2110-10, but our simple test showed that maybe this is not the case. Once the changes were made the occasional “clicks”

We had a great time in Wuppertal – our first ST 2110 products are a “go”!

We recently returned from a most-interesting week in Germany, attending the pre-staging event for the IBC 2018 IP Showcase. We took prototype versions of our new ST 2110-compliant products, the Model 5512 Audio Interface and Model 5518 Mic/Line Interface. The goal was to check and see if they would operate successfully with other 2110-compliant equipment as supplied by manufacturers from literally around the world. After initial testing and some software enhancements (can you say “bug fixes”!) things worked out well.

ST 2110 Products Coming Soon!

Studio Technologies is making good progress with our upcoming set of products that support the new ST 2110 standards. First to be ready will be the line-level analog to/from ST 2110 interfaces. The Model 5512-01 will have 8-in/8-out. The Model 5512-02 will have 16-in/16-out. (See¬†https://studio-tech.com/products/model-5512-audio-interface/ for photos of actual unit.) We’re targeting next month (July 2018) for first field trials.

Development is also going well on the Model 5518 which will have 8 mic/line inputs (XLR3F connectors on the front panel) and 8 line-level analog outputs (DB-25F on the back panel).
