Thanks BogdanH for your reply. It is surely helpful.
Bill,
I have sold my entire old setup including the AV receiver. I don't have any setup now. In my previous setup, i had a Behringer mixer, which received input from
1) G1
2) a wireless microphone (and the mixer would add vocal effects - echo reverb etc)
3) a Bluetooth receiver, to take input of karaoke tracks from my ipad.
The Behringer mixer would mix all three and give output to my Yamaha RX679 AV receiver which in turn would fire the speakers and sub. It worked great. But then I sold it all
I still intend to buy a new mixer (preferably Bluetooth built-in) which will take input from
1) G1
2) Wireless microphone
3) Bluetooth builtin
The mixer needs to now fire the sound bar (Samsung Q990C) instead of the Yamaha AV. But the Soundbar only has optical and HDMI input, whereas I am still to find a decent mixer with Optical or HDMI output
There comes in the role of sub quality converters, which I am wary of.
Hope I am able to explain my configuration to you
Regards
Anand
