## Questions & Answers

**Q: 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?**
A: I believe your unit may be broken.

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

**Q: Is this unit a blue-tooth receiver or a blue-tooth transmitter?**
A: 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.

**Q: What is the max of watts**
A: 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!"
