It was not completely clear in the OAW3 user manual, but the transmitter/receiver combination is two simultaneous channels - yes/no? It can be used for two surround channels is the assumption, as that would be my application.

Also I gained from reading some post here that there is a fixed 20 millisec delay on both channels. Is this true or did I read it wrong? If it is running an 802.11 stack underneath, I would understand some jitter buffers would be somewhere and at least 20 millisec - although I would expect more delay to get through the stack. If it was pure analog, I would expect very little. A fixed delay may be compensated by the system controller or AV receiver, but I would not expect much adjustemnt (across all audio channels) before video sync problems would show up. Is this a bad assumption - any experts on the OAW3 application space? Does the Marantz 5005 have this flexibility?
Thanks.
