Hi Everyone, 

I recently received my Pro-Ject T1 Phono SB and Sonos Five, and I’m super excited about them! I ordered both items separately, as well as an RCA to 3.5mm adapter from Amazon, just in case. Some people say it might be included in the SB, while others say it’s not.

It turns out that it wasn’t included.

I set everything up and was ready to play my first vinyl, but I’m getting a continuous deep buzz through the speaker. I can hear the music, but the buzz is still there, and it’s at all volumes.

I’m using the supplied RCA cables with ground tabs on both ends; however, one of the ground tabs is in free air as I’m using the RCA - 3.5mm adapter. I’ve moved the positions and distances between the T1 and the speaker, as well as moved rooms and turned off other devices. But nothing seems to make a difference.

I did notice that when I move the tone arm, the buzz does seem to change slightly. Touching it alone doesn’t make a difference, but when it’s moved, it does seem to change, but it’s intermittent.

I’ve tried two different RCA - 3.5mm adapters with no change. I’m starting to think it might be the grounding. If so, where should I attach the currently loose earth tab to?

Any advice would be greatly appreciated!
