Easily connected mobile phone by bluetooth, and play music. 24VDC power is supplied, and it makes great sound from a channel. The sound file in USB does not played, and I need the detail instruction. When I switch the mode, I hear some Chinese message, but hardly understand. I can hear faint sound from left channel, while loud right channel. If the detail instruction does not helps, it seems to be better to refund or replace to perfect one.
