A:AnswerYes, plugged in all the time to powered via 110 AC (plug directly into a wall outlet). It does not contain a battery, thus no chargeable feature.
It does work great and have a nice sound making use of Yamaha MUSICCAST, works nicely with Bluetooth and Airplay. It has a nice sound for this type product
and it was fairly easily setup.
A:AnswerI have this speaker in my study, and an Aventage RX-A3050 receiver, which does have Musiccast, in my family room. The Musiccast app is separate from the AV Controller app. You will be able to use the Musiccast app to access your NAS (called Server in the app) and Internet sources for this speaker. You cannot however do whole-house music by synchronizing the speaker with your receiver, because your receiver doesn't have that capability. That's the only drawback. Otherwise, with your current receiver you would have a fine, independent, 2-zone music installation that could play two different music sources simultaneously.
A:AnswerI have not, but I'm not using Bluetooth, it sounds like you might be. If you stream off the internet, the speakers handle the interaction and I've had virtually perfect results now for over a year. We have these run into seven zones and I have never heard a synch issue.
