unable to connect pro-ject T1 to sonos one

What are you connecting the pre-amp to on the Sonos One speaker? It has no line-in port, are you sure it’s a Sonos One?

Hello @Ken_Griffiths ,
i forgot to say that i connect it to a sonos connect.
haha and i‘m sure  it’s a sonos one ;p

If both devices are on the same software (Connects made before 2016 are S1 only) you should be able to choose “line in” on the Sonos One when you play a record,

Ah that makes sense now… er… presumably you have it so the TT RCA line-out goes to the pre-amp (line-in) and it’s line-out goes to the Connect RCA line-in. If the audio is not very loud, then go into the Sonos App ‘Settings/System/[Connect Room Name]’ and try setting the line-in source level higher - set it so that at full volume you do not hear and distortion at/near the full volume level. I would start with source-level 8 and adjust it up/down from there and see if that resolves the issue.

hello @106rallye ,

Actually i connected the phono preampli with sonos connect and i also downlaoded the sonos app to connect with my sonos one but all i heard just a very small volume from my pro-ject T1, any ideas?

Hi @Ken_Griffiths ,

I’ll try again when i get home. thank you for your advice.

Hi @Ken_Griffiths 

i tried what you told me, but it didn’t work😭

Only can hear the small volume from the turntable..

do you have any ideas ?

Form the picture, it looks like there is a port labeled “Input DC” which I assume would be where you’re supposed to connect power to your preamp.  I don’t see any power cable for that device, and it surely would need some power to amplify the signal coming off your turntable.

Yes, I agree with @melvimbe - the pre-amp needs power to work.

Good quality power too, if you don’t want a hum or buzz in the audio.

I’d look for a switch mode supply (not analog) of the proper voltage and with more milliamps of output than you need.
