I just wanted to make myself available for any questions regarding the myMix system. More specifically, I want to clear up any misunderstanding regarding functionality. Like a lot of networked systems, channels on a myMix system travel in pairs. Those pairs can be configured as dual mono or stereo. The number of channel pairs available on a myMix system is theoretically equivalent to the number of multi-cast groups the Ethernet switch can handle. The Cisco switches that we advocate can handle 256 groups. We haven't tested 256, however, we have tested up to 40 pairs on the network with no problems. You can mix 8 pairs on each myMix (configured as dual mono or stereo). The 8 pairs that one myMix selects on the network can be completely different from another myMix.
For instance, if you have 24 channels coming from the stage, you could have all of those as direct outputs from the console into two IEX-16L boxes. That leaves 8 more channels into which you could send 4 stereo submixes from FOH. Those could be drums, vocals, guitars, keyboards, etc. The drummer could select all of his drum mics, and grab vocal and guitar submixes. The vocalists could select the drum submixes and all of the vocal mics, etc.
We really designed the myMix system from the point of view of musicians - names not numbers, intuitive user interface, multi-track recording to SD card. In my very humble opinion, other systems on the market were designed by engineers for engineers. One of the first compliments we get on our system is that musicians can easily begin using it in a matter of minutes. That is key to keeping them in the creative state of mind (which is where they are most comfortable). After all, if it wasn't for musicians none of the engineers in this business would have a job. Somehow, somewhere, musicians became the problem when in reality they are the sole reason for the our existence. But I digress...
Please let me know if anyone has questions.
