with the provided CAT5e cable, I was able to see the comput- ers of the other folks at my table as sources and destinations for audio transmission. The routing and configuration of a network was covered in the first presentation by Audinate's Bernie Farkus—with these little "table-based networks" allowing us to become familiar with navigating the Dante Controller—and getting to know our neighbors. Since a technology such as this can't grow (let alone survive) without manufacturers implementing it into their own products, there were three "Sponsor Speed Dating" segments after sessions throughout the day—giving spon- sors a couple of minutes to talk about how their companies are implementing Dante. Some manufacturers' products were sound reinforcement focused, some were conference centric, and others were general pro audio. It was interesting to see how the protocol is being used in various areas and at opposite ends of the production spec- trum—for example, from a city council meeting on the local TV station to the Super Bowl broadcast. As you can imagine, later sessions got deeper and deeper into Dante. Yamaha's Patrick Killianey gave an excellent pre- sentation with topics such as network- ing audio and how Dante deals with clocking, among other things. The clocking discussion really grabbed my attention. Patrick provided examples of different clocking scenarios such as using AES, a dedicated external clock and Dante. The interesting thing with Dante is that you can assign a master—or it can automatically pick a master based on the connected device that it feels offers the most solid clock. Dante uses Precision Time Protocol (PTP) instead of the more traditional Time Division Multiplexing (TDM) and, as a result, the accu- racy of the clocking is much tighter than using just AES and equal to using an external word clock. Need to apply a pull factor? Just select the desired pull factor in Dante Controller. As you would expect, there were some interesting screen grabs to validate the accuracy discussed. Of interest, Yamaha has posted six networking tutorials on YouTube. Search: Networking Fundamentals for Professional Audio. Mixed between the sessions and the sponsor presenta- tions, some guest users discussed how they've implemented Dante into their workflows and setups. One guest speaker was Matt Wentz, the Audio Systems Engineer from Willow Creek Community Church located outside of Chicago. The designation of "church" downplays the size of this church Pull factors Right: Audinate's Bernie Farkus gets the day going with a Dante overview.
