See pp19-20 in the WiiM Amp manual which refers to bluetooth out (kind of essential for headphone use ) and airplay cast which the Pro and Pro Plus have. Also, if the Amp DAC has digital filters, that's where I would expect to see them. The app currently doesn't have an Audio Output menu at all to configure those options.Can you elaborate this? Audio out? As far I’m concerned all connection on wiim amp are all inputs. If what you’re saying is indeed true, this is the function I rather have to connect my mono block amp. If wiim can reverse engineering function of the rca that can be use either in or out via firmware update many will be floored.
I'm not expecting any more than that.
