14-Nov-2022 AES67 Model 5401A Model 5402 ST 2110

Supporting PTP v2 (AES67 and ST 2110) with the Model 5401A and the Model 5402

The Model 5401A Dante Leader Clock and the Model 5402 Dante Leader Clock with GNSS Synchronization were primarily designed for use in applications that utilize devices running “native” Dante. To support the timing needs of these devices Precision Time Protocol Version 1 (IEEE-1588-2002 or “PTP v1”) was implemented. The units’ 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 5401A and Model 5402 units.) Even in large installations with literally hundreds of Dante devices,

16-Aug-2022 Dante Recommendations

Network Equipment for Dante Applications

Over the years people have asked us if there were specific makes or models of networking equipment that we could recommend. Their goal was to optimize their network deployment to function well with our Dante®-enabled products. Our standard reply has always been that any Ethernet networking equipment that complies with the relevant IEEE® standards should work acceptably. We were hesitant to recommend any specific equipment as there were many fine brands of equipment that could meet the requirements.

How to Repair StudioComm and Model 400 Pushbutton Switches

Studio Technologies has created a video which provides details on how to repair the pushbutton switches that are used in the StudioComm desktop control consoles and Model 400-Series fiber transport units. Typically only a cleaning is required to return them to full working order.

 



Cleaning typically only requires a small flathead screwdriver or a thin plastic pry tool, a pencil eraser, a cotton swab, and a can of contact cleaner.

14-Jun-2022 AES67 Dante ST 2110

DSCP Tag Values

Dante® audio-over-Ethernet networking technology can support the requirements of the AES67 and SMPTE® ST 2110 technical standards. Studio Technologies offers a number of Dante-enabled products, all of which are capable of having their AES67 and/or ST 2110 capability enabled. This is performed using the Dante Controller software application.

For compatibility with a number important AES67 and ST 2110 technical parameters, Dante was required to implement several DSCP (Differentiated Services Code Point or DiffServ) tag values.

14-Mar-2022 Performance

Ping Command – 32 versus 56 Bytes

The ping command can be very useful, helping to determine if a network-connected device is available and functioning correctly. (Ping is a utility that was developed in the 1980s and utilizes the ICMP Echo Request and ICMP Echo Reply network resources.) The management ports on a number of Studio Technologies’ products support the ping command. These include the Models 792, 5401, 5401A, 5402, 5412, 5418, 5422, 5422A, 5482, 5512, and 5518. It’s important to note that one user issue can arise when “pinging”

28-Jan-2022 Dante Intercom Audio Engine Model 373A Model 5422A Performance

Creating a Basic 2-Channel Party Line Setup

Using the Model 5422A Dante Intercom Audio Engine and four 370A Intercom Beltpacks one can route a simple two channel party line setup in Dante Controller. Before any routing can be completed a few necessary pieces of software must be installed. The most important is Dante Controller which is free to download off of the Audinate website. STController is available on our website and any internet browser (Chrome, Edge,

16-Sep-2021 Dante Intercom Audio Engine Model 5422A Performance

Creating a Party-Line of more than 32 Channels

A Model 5422A Dante Intercom Audio Engine has a maximum group size of 32 channels. (In this case, the one group would be using all 32 channels of an audio engine.) So, in theory, a 32-channel group configured for the Party-Line operating mode would allow a maximum of 32 users to be part of that party-line (PL) circuit or channel. In the vast majority of applications that should be sufficient; having anything close to 32 users on the same PL would be an exception.

12-Jul-2021 Model 76 Testing & Troubleshooting

Model 76 High-Frequency Oscillation Issue

The Model 76 Central Controller was manufactured for a number of years but was discontinued in August of 2012 due to parts availability and decrease in demand. It was an excellent product that is still in use by many facilities. We have become aware that after ten or more years of field operation an oscillation in the range of 17-18 kHz can appear in the unit’s analog output channels. It was found that the unit’s –15 volt DC power supply “rail”

11-Jan-2021 Gooseneck Microphone New Release

Gooseneck Mic Released

Recently, Studio Technologies released the GME-3-12 Gooseneck Microphone. It’s an excellent unidirectional, electret, close-talk microphone that’s mounted on a miniature gooseneck shaft and interconnects using an industry-standard threaded bushing with integral 3-conductor 1/4-inch plug. Working with an excellent vendor in Japan, the GME-3-12 was created specifically for intercom and voice paging applications. It had to meet a rigorous set of acoustic and mechanical requirements before we knew it would be “right” for our customers.

06-Nov-2020 Dante Firmware Updates Model 5422

New Firmware Enhances Model 5422 Dante Intercom Audio Engine Performance

Studio Technologies has released new Main and FPGA firmware (embedded software) for the Model 5422 Dante® Intercom Engine product. The first major update since the product was first released in early 2017, it ensures that the Model 5422 maintains industry-leading performance along with a better user experience. Version 2 adds new capabilities and expanded options for both the Model 5422-01 (32-channel) and Model 5422-02 (64-channel) versions. All newly shipping Model 5422 units will incorporate the new firmware.
