Hello. i just unpacked my unit, and when i plug it in, the led display does not come on, how do i get it to activate? is my unit broken?

I believe your unit may be broken.

Speakers a and c work but b and d do not. not even the same channel, any ideas ??

Kenneth's answer isn't correct. The subwoofer connects through the RCA port on the lower right. I'm not sure why only half of your speakers are working.

Is this unit a blue-tooth receiver or a blue-tooth transmitter?

think of it as an audio receiver through a Bluetooth or aux connection - your phone would connect to it over Bluetooth (or a stereo 3.5mm cable if your phone has a headphone jack) and send Spotify or other music to this device, which would send the audio out through speaker wires.

What is the max of watts

I'm not sure of the max watts, but it gets really loud even at 15. I have to constantly yell down to my son to "Turn It Down!"
