Network- systems with a maximum of 16 audio
channels
A typical myMix system consists of multiple units. myMix units connect to each other with
common CAT5 cabling through a standard off-the-shelf unmanaged 100MB Fast Ethernet
switch. If you are just using two myMix units, or a myMix and one IEX-16L, you can connect
them directly to each other without the need for a switch. Three or more units in a system will
require a switch. For up to 16 audio channels most off-the shelf switches work.
NOTE: Don't combine myMix units with other network able devices, the myMix system network
needs to be exclusive. It is not possible to combine several myMix units in a network with other
network able devices such as PCs, routers, modems or printers.
Network- systems with more than 16 audio channels
Audio signals on the myMix network are streamed in pairs as one stereo signal, or two individual
mono signals. Each myMix can create a mix using up to 16 audio channels (or 8 pairs). Using
one or several IEX-16L input expanders, the amount of total available channels on the network
can easily exceed that number. What is required, is a managed switch that supports IGMP
snooping and is configured accordingly. The amount of audio channels on the network is
capped by the number of multi-cast groups the switch supports. A typical value for managed
switches is 256 multicast groups (= 256 audio pairs), which equals 512 individual audio signals.
Selecting and Configuring Ethernet Switches
Managed switches usually require additional configuration before you can use them with
myMix, even if you are not using more than 16 channels on the network. Here some basic
guidelines for configuration of up to 16 channels:
1) Connect a computer to the switch using one of the 100MB ports and log on.
2) Create a VLAN #2 and put all ports you want to use in that group.
3) Make the outputs “Tagged” ( don‘t strip the tags, leave as is).
4) Before you log out from the switch make sure the settings have been saved.
While myMix works with most Fast Ethernet switches, they differ widely in the way how they
need to be set up and how they support certain functionality.
