[...] MY ethersound card for yamaha console 1 slot and duplicate sends out to 2x es168 boxes ... not concerned about the inputs but ideally they route 8 each for box 1 and 2 ... is this possible to setup though a managed switch?? [...]
Just leafing through the
Yamaha EtherSound Setup Guide it looks like that kind of output duplication should be easily achievable with or without a switch (which, to my knowledge, doesn't
have to be managed, but it's probably not a bad idea).
With a switch it looks like you won't be able to access at least one (if not both) of the SB168-ES's inputs, whereas
without a switch it looks like you might well be able to achieve the setup you describe just by configuring the I/O Patch settings for each device in ES-Monitor. (Of course, this is just based on what I'm reading; I don't have any meaningful experience with EtherSound...)
