And you understand me: buying a dongle for a few thousand euros would like to know and believe that this product is worth the money, and at that moment when I need help I can seek it to the professionals and they will help, or he read it in the manual, but when something is not in the manual start looking for an answer on the internet and can not find anything, Then ask the question on the forum where I meet the "use sync ..." and how it works and how to configure it is not written anywhere and no one wants to say no, that is, I need to buy a pair of external devices and try yourself, and then throw them away realizing that this is not something that I fondly look back and then all of the Internet and then again to buy and try?? I thought that technical support is a support and not to the ignorant people who earn money! I do not blame that Catalyst does not support the playback of audio files, and that there is no simple external audio player that is easily synchronized to the network to another Catalyst and all it would be convenient!
Thank you very much for the detailed description! If I have questions I can for you bridle? Or should I look for people who earn money from it? I'm sorry to put it crudely
