More than one wise grandmother has said, “When life gives you lemons, make lemonade.” In this new time of social distancing and sheltering in place, why not squeeze in (see what we did there) a little professional development into your busy schedule of Netflix, walk the dog, make a snack, Hulu, think about exercising, make another snack.
Learning about AVB doesn’t have to involve stacks of IT manuals. PreSonus has put together all the resources you need to discover what this exciting audio networking technology can do for you.
Here are Ray “The Beard” Tantzen and Mike “The Brainiac” Cole to tell you a little more about a little thing called AVB:

Before taking a deep dive down the AVB rabbit hole, take a quick refresher on what audio networking is and some of the fundamentals. As its name implies, audio networking allows you to transport large amounts of data over a single cable. This means that audio can be moved quickly over long distances without signal degradation or the expense of conventional analog cabling.
From distributed audio to network foundations and addressing, this article will get you started:
AVB (Audio Video Bridging) is an extension to the Ethernet standard designed to guarantee that audio samples will reach their destinations on time. AVB allows you to create a single network for audio, video, and other data like control information, using an AVB-compatible switch. It’s also the networking technology that all PreSonus StudioLive Ecosystem products use.
AVB networking offers several features that make it ideal for audio applications, find out more here:
P2P? Star? Daisy-chain? Whether you’re connecting a mixer straight to a stagebox using AVB or configuring a large system for broadcast, figuring out the best way to create your network is critical to ease of use and system performance. Check out this article to learn which configuration or combination of configurations will work best for you:
Okay, not that kind of hop, but it’s still pretty hip (Dad joke Level 16: unlocked). A hop on an AVB network is counted by the connections between AVB switches in a series. Luckily, you can make up to six hops before your network stability is effected, but it is something to consider when configuring your network. Find out why here:
Like all digital audio systems, all the audio traffic on an AVB network is synchronized using a global clock so that audio can be played and recorded while remaining in time from multiple sources. Obviously, the more audio traffic on a network, the more critical this becomes. For users familiar with traditional digital audio devices (ADAT, S/PDIF, etc.) the idea of a global clocking device will not seem unfamiliar. PreSonus AVB devices have two clocks: one wordclock and one PTP clock. Get out your pocket protector, we’re about to get geeky:
OMG. Stop. Go for a walk or something, you’re about to read a technical article on Ethernet cables!
You asked for it…
AVB networks rely on a set of standards for cabling to ensure that network performance is both reliable and consistent. These standards include specifications for the cable construction itself, as well as specifications for the termination of cabling and physical connections to devices. Deviations from these specifications can result in reduced performance and even data loss, so it’s important to use the right cable for the job, and to use good quality cable that meets the necessary specifications.
