Production and Availability Status

Studio Technologies has not been immune from the current global supply-chain issues. This has impacted the ability to build a number of products. Below is a list of the units that have been affected, along with a brief overview of the action Studio Technologies is taking to try and ensure that the level of service and quality our customers have become accustomed can continue. This list will be updated as the status of the affected products change. From problems come opportunities and that’s the mantra that Studio Technologies has adopted. It’s a difficult time for everyone but together we’ll get through it!

    Model 43D Audio Interface Production Delayed
    As late July 2022, only a few Model 43D units remained in the Studio Technologies’ inventory. Further production is on hold due to the unit’s microcontroller integrated circuit becoming difficult, if not impossible, to obtain. Orders placed for this part in early 2021 are currently scheduled for delivery in Q3 of 2022. But that’s not certain. The old adage “we’ll believe when we see it” seems to be appropriate right now. When this part arrives production will commence. An alternative path being contemplated is for the Model 43D to be re-designed using a different microcontroller integrated circuit. This is a reasonable idea but an alternate part must also be available for a redesign to make sense. That’s problematic and will be considered before a path is selected.

    Model 214, Model 215, and Model 216 Announcer’s Consoles being Updated to Models 214A, 215A, and 216A
    The venerable Models 214, 215 and 216 have been part of the Studio Technologies’ line of Dante announcer’s consoles for a number of years. However, during 2022 obtaining some of the integrated circuits used in these products became became extremely difficult. It was decided that this problem was actually an opportunity to update the units. (The situation was the catalyst (i.e., “the kick in the pants”) we needed to get busy!) The new units, to be called the Models 214A, 215A, and 216A, are expected to be available early in Q4 of 2022. The price, size, and user features will remain the same. Audio performance will meet or exceed that provided by the original units. Configuration will be performed using the STcontroller application, eliminating the need for DIP switches, pushbutton switches, and LED displays.

    Model 44D Audio Interface Obsolete; Model 544D Audio Interface Under Development
    During 2020, the microcontroller integrated circuit and digital audio integrated circuits used in the Model 44D Audio Interface started becoming very difficult to obtain. Demand for semiconductor parts, along with the devastating 2019 fire at AKM in Japan, has had a major impact on delivery of parts to OEM manufacturers, including Studio Technologies. As such, no Model 44D units have been produced since Q3 of 2021. (And all units in the Studio Technologies’ inventory have since been shipped to customers.) The lack of semiconductors needed for the Model 44D continues and it was decided that the unit would be discontinued. But the need for such a product continues and an updated unit, to be called the Model 544D Audio Interface, is currently being developed. Challenges with the selected NXP microcontroller integrated circuit have caused an additional design cycle (“board spin”) to be required. When complete, the new design will perform the same functions as the Model 44D but will use newer parts, use STcontroller for configuration (no DIP switches on the unit’s back panel), and it will be housed in our latest enclosure design. It’s expected that the pricing of the Model 544D will be the same as the Model 44D. Production of the Model 544D is expected to begin during the latter part of Q3 of 2022.

    Models 232, 234, 236, and 348 Production Delayed; Delivery Date Scheduled
    The Broadway integrated circuit is used to create the Dante interface in the Models 232, 234, and 236 Announcer’s Consoles and the Model 348 Intercom Station. Late in 2021, Audinate essentially halted deliveries of the Broadway chip to all OEM customers, including Studio Technologies. This was due to Audinate’s inability to source the logic integrated circuit that forms the core of the Broadway part. This lack of delivery prevented Studio Technologies from building more of these units once all inventory was shipped to customers in early 2022. Fortunately, Studio Technologies subsequently received delivery of some Broadway parts and production has resumed. It’s expected that Model 232, 234, 236, and 348 units will again be available later in Q3 of 2022.

    Model 45DR Intercom Interface Obsolete; Model 545DR Intercom Interface Remains Under Development
    The Model 45DR provided excellent performance since its release a number of years ago. Unfortunately, during mid-2021 obtaining some of its parts became quite difficult. This included an inability to obtain the microcontroller integrated circuit used by the unit. As such, it was determined that further production of the product was not possible. However, the need for the unit’s functionality was still present so Studio Technologies decided that creating an updated unit was warranted. Development of a replacement product, called the Model 545DR Intercom Interface, began in Q3 of 2021. A new microcontroller integrated circuit was selected for the design (manufactured by NXP) and incorporated into prototype hardware. Units were built and firmware was developed. It appeared that this was going to be a good solution. Unfortunately, extensive testing determined that this NXP part contains a hardware problem when transporting serial audio data when locked to an external clock source. This issue manifests itself by random “flips” of the left- and right-channel PCM audio data. It was determined that there was no hardware or firmware “work around” to remedy this issue and that the design was not suitable for customer use. So it was decided that an issue of this severity required changing the design to use a different microcontroller integrated circuit. Along with that change another re-write of the unit’s firmware would be necessary. As of the writing of this technical note, the re-design has been completed, prototype units are being manufactured, and firmware development will begin within the next few weeks. Once that has been completed the remaining step will be final performance testing. Once performing to the necessary standards, production of customer units will commence on a rapid schedule. When completed, the Model 545DR will perform the same functions as the Model 45DR, will have the same price, and will utilize more-available technology. It will also allow configuration and monitoring using the STcontroller software application. It is expected that the first Model 545DR units will be shipped to customers during October of 2022.

    Model 45DC Intercom Interface Obsolete; Model 545DC Intercom Interface Moving into Production
    The Model 45DC has provided excellent performance since it was released a number of years ago. Unfortunately, during mid-2021 obtaining some of its parts became quite difficult. This included an inability to obtain the microcontroller integrated circuit used by the unit. As such, it was determined that further production of the product was not possible. However, the need for the unit’s functionality was still present such that Studio Technologies decided to create an updated unit. The replacement product, to be called the Model 545DC Intercom Interface, began in Q3 of 2021. Getting the performance to the required level has been a challenge but it appears that the process has now been completed. The only step remaining is final performance testing of prototype units. The Model 545DC will offer the same resources as the Model 45DC, be priced the same, and will utilizes newer and more-available technology. It will also allow configuration and monitoring using the STcontroller software application. Availability is expected to be later in Q3 of 2022.

    Model 362 Listen-Only Beltpack Obsolete; Model 362A Listen-Only Beltpack Expected December 2022
    Due to difficulty in obtaining a specific microcontroller integrated circuit, Studio Technologies has not been able to deliver Model 362 Listen-Only Beltpack units since Q3 of 2021. The outlook for availability of that component was not promising so it was decided that an updated version of the product was warranted. Development of a replacement was going well and a revised product, to be called the Model 362A, was expected to be available in mid- to late-Q2 of 2022. However, meeting this delivery date became impossible as availability of another component became the limiting factor. While delivery of Ultimo integrated circuits used for the Dante interface function was scheduled, Audinate was unable to deliver them. The current Ultimo delivery schedule as provided to Studio Technologies should allow delivery of Model 362A units in December of 2022. When finally released, it’s expected that the Model 362A will be a strong product. It will use a different and hopefully more-available microcontroller integrated circuit. In addition, other portions of the circuitry have been changed to reflect Studio Technologies’ latest design practices. This includes removing the four configuration DIP switches and utilizing the STcontroller software application to configure the unit’s operating parameters. (See the latest version of STcontroller for Windows® for the Model 362A’s configuration implementation.) Several additional changes should result in increased overall unit reliability. So while current conditions have forced yet another delivery delay, the result should be very positive for the longer term.

    Model 5421 Dante Intercom Audio Engine Delivery Expected August of 2022
    The Broadway integrated circuit (“Broadway chip”) from Audinate is used to create the Dante® interface in the Model 5421 Dante Intercom Audio Engine. Late in 2021, Audinate essentially halted deliveries of the Broadway chip to all OEM customers, including Studio Technologies. This was due to Audinate’s inability to source the logic integrated circuit that forms the core of the Broadway part. This prevented Studio Technologies from building more Model 5421 units. Inventory of Model 5421 units was depleted by early in 2021 with no more available since then. The long-term outlook for the Broadway part was not known. However, since then Studio Technologies has received a delivery of some Broadway parts and production of additional Model 5421 units has began. It’s expected that units will be available in August of 2022.
