AUDIO NETWORKING
Networked Audio
myMix is a networked audio system which utilizes off-the-shelf 100Mbs networking hardware and standard Cat5 cables to distiribute signals across the network. Signals can be injected onto the network via the two local myMix inputs, an IEX-16L, or a combination of both. A name is assigned to each signal which all myMix units on the network can see. Non-linear functionality with channel names keep musicians in the creative mindset, versus the engineering-driven linear nature of traditional mixing consoles.
 
Network Channel Pairs
Channels on the network travel in pairs. A pair consists of inputs that are physically next to each other. For instance, the two inputs on each myMix always travel in pairs. Odd-even inputs from the IEX-16L also travel in pairs (1&2, 3&4, 5&6, etc.) Each network pair can be configured as dual mono, stereo, or disabled from the network.
When a pair is configured in stereo the audio comes in discreetly left and right and shows up as one named fader on the screen.
A stereo pair still counts as two channels on your main mix screen. Dual mono signals are two uniquely named, pan-able and mixable channels. While these signals always travel together, you have the choice of only selecting one member of the pair. It is important to keep in mind that although you have only selected one member of a pair on your mix screen, the pair counts as two channels against the 16 you can mix.  
Available Network Channels
While each myMix can mix up to 16 channels, it can have access to many more. The number of pairs that can exist on a network is limited by the number of multi-cast groups that your Ethernet switch can handle. Each user can decide which 8 network pairs (or 16 channels) they want to mix.
For instance, if you have 32 channels coming from the stage to the mixing console, you could have all 32 direct outputs routed to a pair of IEX-16L input expanders, and have those available on the network.
A third IEX-16L could be accepting 8 stereo sub-mixes like drums, vocals, guitars, keyboards, etc,
also being added to the network for a total of 48 available network channels. The singer may have no interest in mixing the entire drum kit, but would rather have a stereo drum sub-mix and each additional vocalist independently. The drummer on the other hand, wants full mixing control of the drum kit, but only wants a stereo sub-mix of guitars, vocals and keyboards. This allows tremendous flexibility to tailor the system to every performer’s needs.
 
AVB Networking Protocol
myMix uses a modified AVB network to operate on standard hardware. AVB is an open source protocol that is currently pending standards ratification by the IEEE. As soon as the protocol is standardized, and AVB switches are available, a simple firmware update will take myMix to full AVB readiness. The AVnu Alliance is a great resource for AVB and its intended applications.
