Merry Christmas!

Also I recieved a Project debut carbon turntable and a Yamaha integrated amplifier A-S500.

Long story short I have assembled everything, and I am getting a terrible sound through the phono input. It sounds worse than a cell phone speaker. I have tried the see if it was the receiver making the noise, but the other inputs sound great.

What could be making my turntable sound so terrible and unlistenable?
