On receiving did not work. first the microphone playing up. and on the reverb unit , the reverb would not turn off completely . My son builds computers so he had a look at the products for me.
He sorted out all joins and all is now okay. saved sending back. its a bit expensive for what it is in my private opinion . a honest review .
I Have my pc connnected to amplifier (which is then connect to the tv) via HDMI. I can use the machine with 2 mic's to connect to the pc via the usb. Using it then to stream online karaoke and all Mic sound is blended well with online music.
