15-Feb-2024 Dante STcontroller Testing & Troubleshooting

Devices Not Appearing in STcontroller

As of the writing of this document (14-Feb-2024), the latest versions of Dante® Controller are for Windows® and macOS®. For unknown reasons, Audinate decided to remove the “Use Shared Dante interface” checkbox from these software versions. The release notes for these versions state:

The “Use Shared Dante Interface” option has been removed from the “Configure Dante Interfaces” dialog, to provide a simpler and more consistent user experience across Audinate software products.

PL Call Signals and the Dante Intercom Audio Engine Auto Mix Function

High-frequency in-band call signals are often associated with party-line (PL) user intercom devices. Typically 20 kHz and contained within an audio channel, these signals can be used to activate (“trigger”) a visual and/or audible indicator on a user beltpack or console device. A number of Dante®-enabled devices from Studio Technologies support this type of call signal. At the present time, high-frequency call signal capability is typically not compatible with the auto mix function as implemented in the Studio Technologies’

How to Fix an Empty Device List in STcontroller

Studio Technologies has created a video which provides details on how to fix an empty device list in STcontroller. Typically, a simple selection within Dante Controller is all that is needed to restore full functionality.


If the device list within STcontroller is blank, the correct Dante interface is probably not selected. One might also notice that their network interfaces listed in the drop down menu cannot be selected. 

This results in STcontroller failing to identify supported Studio Technologies Dante products on the network thus leaving the device list empty.

How to Update Main and Dante Firmware on Studio Technologies Devices

Studio Technologies has created a video which provides details on how to update the main and Dante firmware on compatible Studio Technologies devices. Typically only a USB drive and a computer are required to update the units.


Updating firmware typically only requires a USB drive and a computer to fully update all Dante compatible units. Some units require the front cover to be removed first before a USB drive can be inserted,

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.

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.

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.

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.

Interfacing Unity Intercom to Analog Intercom using Dante

We often get calls from customers looking to connect their existing analog intercom systems to the intercom solutions provided by Unity Intercom. This can be easily done by installing Dante® Virtual Soundcard on the Mac running Unity Server. Then Dante Controller can be used to route any Dante audio to/from the Unity system.

Studio Technologies’ Model 44D Audio Interface is intended to be used to connect two channels of analog 4-wire intercom to a Dante network.
