Upsizing Small Studios to AoIP


You know the saying that a rising tide lifts all boats? 

As studio projects go, the boats don’t get much smaller than student-run CFAK-FM in Sherbrooke, Quebec. This little college station recently moved into two new studios in the center of Université de Sherbrooke’s busy campus, having outgrown its one-room studio in the residential hall that lacked air conditioning. 

They went with our self-contained, AoIP networked DMX consoles to save on wiring and other costs associated with an analog alternative, an important consideration for a station that was Internet-only just a few short years ago and now broadcasts on 88.3 FM. 


“The money for this project was provided by the students. They believe in the station so we wanted to create a radio station that was on par with any station you’d find in Montreal,” said CFAK-FM GM Eric Laverdure, who partnered with Marketing Marc Vallee in Quebec on the project. 

CFAK-FM’s new studios certainly rival any studio today, but hardly tip the scale in size compared to a recent Wheatstone multi-million-dollar contract that includes LXE/DMX digital audio consoles and WheatNet-IP audio networking for 247 studios in 32 U.S. markets.

Both happened to be rolling through our factory about the same time – one huge whale of a project next to this two-studio project that included two compact networkable consoles and a couple of talent stations. 

Our point is that AoIP raises all boats, big and small. In fact, the technology we perfected over the years for multi-studio projects has made it possible for us to scale AoIP for smaller stations like CFAK-FM. For example, CFAK-FM’s DMX-16 and DMX-8 console surfaces with mix engine come with IP audio I/O and are fully self-contained with no external Ethernet switch needed. These compact consoles are the very definition of plug-and-play IP audio networking. At any time, CFAK-FM also can add WheatNet-IP Intelligent Network software such as ScreenBuilder for building virtual interfaces or IP Meters for monitoring signal flow, just as any larger, multi-studio operation using WheatNet-IP audio networking would. 


And it’s fair to say that those synergies go both ways. Remember that large project we mentioned earlier? It just so happens that many of those AoIP consoles are DMX-8 or DMX-16 console surfaces, the very same in use at CFAK-FM’s new studios. 

When the Chips are Down

SMPTE June 2021 v6


By now, you have heard about the fire at AKM’s plant in Japan and the loss of almost half the world’s supply of high-end AD/DA chips. It has affected the manufacture of everything from cameras to AoIP systems and has caused production lines to come to a grinding halt.

This isn’t the first time we’ve seen component shortages in the 40+ years Wheatstone has been manufacturing broadcast products. But it’s certainly one of the more impactful and adds to an already volatile semiconductor supply chain. Even the common capacitor has hit 60-week lead times. 

With all this going on, you’re probably wondering how Wheatstone is able to double down on manufacturing. You might even be surprised to learn that we are currently wrapping up a multi-million-dollar contract that includes more than 200 console surfaces, 1,000 WheatNet-IP Blades, 250 mic processors and 200-plus VoxPro digital recorder/editors. 

We are less affected by recent events than most because we’ve invested in large inventories of materials and parts. It’s why we can run our production plant at full capacity this year and the next while others are still struggling to meet current factory runs. 

And it’s exactly why we have in stock and on hand critical components like the AKM audio chip mentioned earlier. Just about every company that makes pro audio, MI or broadcast products uses high-quality ADC/DAC IC components from AKM and one or two other suppliers for analog-digital/digital-analog conversion. Some, like Wheatstone, use ADC/DAC chips from more than one supplier to hedge against single-source bottlenecks like the one we just experienced. 

Why is do we go to such extremes? Because without a steady stream of products coming out of our factory, studio deadlines would be pushed back, budgets would go through the ceiling, and we couldn’t be that partner that every broadcaster needs when they take on one of the most important projects of their careers.   

Blading Up for a Disaster


If you want to see how effective your emergency plan is, just go on vacation. 

One engineer we know was at home during one uneventful Christmas vacation. There were no panic calls, no late-night trips to the transmitter, nothing at all to indicate that the STL at one of his transmitter sites had been hit by lightning. 

He had spent the week at home blissfully unaware that something was wrong. Another week passed before someone mentioned to him that the song title and artist information for one of his stations wasn’t coming up on their HD Radio.

He then made the trek to the transmitter site and discovered that the main 6 GHz link had been hit by lightning and had automatically failed over to the backup 900 MHz STL. The WheatNet-IP I/O Blade at the site had detected silence immediately after the lightning hit and had transparently switched over to the backup STL while he was at home, enjoying the holidays with family and friends. The only clue there’d been a failover was the missing HD Radio song identifier, data the backup doesn’t carry.   

He thought of that Blade a few months later when a storm surge dumped a massive wall of water on the studios and another transmitter site lost programming. Once again, a Blade at a transmitter site detected silence from the studio and in this case, failed over to the backup automation machine onsite until he could restore connection. 

As this engineer discovered, Blades can be especially useful at the transmitter site as a final workaround in an emergency because they have silence detection, flexible GPI logic and salvo programming for all kinds of situations.

We recently heard of a Blade being used to automatically rotate a backup transmitter between four FM stations that were running off generators after a Cat 4 hurricane knocked out power to the region. Fortunately, this engineer planned for the possibility that the stations could be running off generators for a while. Not only did he have a maintenance plan to keep backup generators running for more than a month, he also had WheatNet-IP control and routing that made it possible for him to easily switch the backup FM transmitter between four FM frequencies and program feeds by setting up a salvo and using the GPI logic on the Blade. 

These are a few of the many examples of why putting a Blade at the transmitter makes sense,   but let’s not forget how useful having a Blade in the studio can be during an emergency. 

We’ve lost count the number of times we’ve heard about broadcasters grabbing a Blade from the studio during an emergency and because every setting for the network was stored in that one Blade, were able to restore AoIP connectivity to the studio and continue broadcasting from home after a flood, fire or tornado.

Getting Streams Cloud-Ready and CDN Compatible: Politics and Protocols


The broadcast industry is currently in a transitional phase, heading toward a world in which a large portion of listeners will receive the station’s program via an Internet stream. Many accomplished engineers and station managers, while experts in traditional radio technology, find themselves feeling like neophytes once again when it comes to Internet streaming. For an overview of this new world as well as standards and practices, be sure to catch Rick Bidlack’s session Politics and Protocols of Getting Streams Cloud-Ready and CDN Compatible at the upcoming BEIT conference, Tuesday, October 12 at 11:30 am during the NAB show.
