06-Sep-2018 ST 2110

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.

06-Sep-2018 Dante Firmware Updates Model 48D

New Firmware for Model 44D Interface – Now Generates 18 kHz and 20 kHz tones.

In August 2018 version 2.2. of the Model 44D Interface’s application firmware was released. This new firmware revises the tone generation capability, keeping the 18 kHz sine-wave but replacing the 1 kHz with 20 kHz. This change was made so that the Model 44D can better assist a matrix intercom and related audio devices in generating intercom user “call” signals. The change may appear to be fairly subtle, but it continues to expand the ability of Studio Technologies’

New Video about the Model 5422 Dante Intercom Audio Engine

Our friend Matt Mayer created a nice introduction and training video for our Model 5422 Dante Intercom Audio Engine. You can find it on our website at https://studio-tech.com/model-5422-dante-intercom-audio-engine-introduction-tutorial-video/.

It’s short and moves fast but we hope it provides some nice background, application, and how-to-use information. You might need to watch it a couple of times to allow all the content to sink in.

If you have a Model 5422 ensure that you’ve loaded the latest firmware.

New Remote Control Feature for Models 214/215/216

In late April 2018 new application firmware for the Model 214, Model 215, and Model 216 Announcer’s Console was released. Each is version 2.2 and they are available for download on the Studio Technologies website. This version adds the ability to use STcontroller (1.05.00 and later) to remotely observe and, if desired, revise the headphone output gain range. This can be very useful, especially in situations where headphone performance requirements change on an event-to-event basis.

14-Jun-2018 Dante Firmware Updates Model 5422

New Model 5422 Main Firmware

We’re pleased to announce the release of main firmware version 1.12 for the Model 5422 Dante Intercom Audio Engine. The new version includes improvements to the unit’s FTP and HTML performance and reliability. There are also a number of other internal updates and enhancements. To user’s the only thing that may be noticed is that several of the text names associated with the IFB function have been revised for clarity.

Version 1.12 applies to both the Model 5422-01 and Model 5422-02 configurations.

Model 41 vs. Model 42A Comparison Chart

Over the years people have asked us to describe the differences between the Model 41 Interface and the Model 42A Interface. The answer is simple: Both units unit have the same circuitry, perform the same functions, and have four 3-pin male XLR connectors on their back panel for access to the powered IFB outputs. But the Model 42A also has four 3-pin male XLR connectors on its front panel. This can be useful when you need direct,

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).

05-Jun-2018 Analog Intercom

Testing and Troubleshooting Analog Party-Line Intercom Circuits

For testing and troubleshooting analog party-line (PL) intercom circuits we think that there’s nothing better than the MR-PRO from NTI Instruments. (https://www.nti-audio.com/en/products/minirator-mr-pro-mr2). While it was designed as a general-purpose audio generator with some test capabilities it ends up being fantastic for analog PL intercom work. It will directly measure impedance and DC voltage, independently from pin 2 to pin 1 and from pin 3 to pin 1, exactly what you need to understand a PL circuit’s characteristics.
