Update:
Bob, I just saw your reply to LilyAarseth re mp3 -> to Mac as zone. Embedded therein, I think, are the answers to my questions. Please confirm that I the following right:
1. Names listed under Playing Now in the left menu ARE ZONES. If I right-click on Streamer, I get a contextual menu including, near the bottom, "Associate with DLNA server."
2. When I click to expand "Associate with DLNA server," I see "Only one server, used by default."
3. When I right click on Player (a zone) the contextual menu does not offer the option to associate with a server. I take it this means the Player zone is never a DLNA renderer, but is playing directly from the Library in MC's server.
4. If I click on DSP Studio in the contextual menu for Player, the pane shows no values entered in the parametric EQ. If I select Options/Add or Configure DLNA Servers/Advanced/DSP Studio, it shows my notch filters in place.
5. Therefore I deduce that this is exactly the setup I want: My main wired system (Player zone) ignores DLNA altogether, and my DLNA renderer (Streamer zone) uses the DSP settings associated with the default DLNA server. If I wanted a different renderer to use different settings, I would first create a second new DLNA server, configure the DSP settings under Advanced, and then go to the left menu, right-click, and associate the new renderer (zone) with the second server. Do I have this right?
I don't see a way to name each new server; they seem to take the name of the DLNA type/format, so their list entries can be redundant. This would make it challenging to keep straight which server configuration went with which zone if multiple servers had the same "name" (type/format) in the list of servers. Maybe you could add a "rename" item to the contextual menu when you right-click a server in the list?
Thanks!
