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.

There is that one silver/gold cable that looks like a speaker cable, and I can’t tell what it’s connected to, if anything.  That could be the power cable?  I don’t know.

The pre-amp should come with the DC power supply according to this Amazon link (albeit casing is slightly different, it is a Pro-ject Phono Box MM):

It’s probably hidden away beneath a cardboard partition in the packaging, perhaps?

That’s the turntable ground.

Hey Guys… @buzz @Stanley_4 @Ken_Griffiths @melvimbe @106rallye 

Are you convinced this is a legitimate OP. It’s been three (3) hours since a response and it was identified three (3) hours ago by @melvimbe that a power supply was needed and yet still no response from the OP. Furthermore the OP lists in her profile the following:

• Country Paris
• City France

Don’t get me started on that...😂

Any who….carry on fearless community members. You’re doing a great job. Not that you require my approval 😂

Hello everyone,

thank you for all your advices.

i’ll try it again tomorrow.

sorry I got back to you guys so late.

i have a full time job and after my full time job ,I have a part time job this is the reason why..

Thanks a lot. I’m appreciated🙏

Even if the OP had not replied @AjTrek1, my own thoughts are, it doesn’t really matter that much anyway, as this thread might one day assist some other users who may frequent these pages, with the same/similar issue.

I do have far more of an issue with the Sonos community ‘search facility’, as it’s still rather difficult to (re)search a good many things on the forum here and to find helpful information. If it wasn’t for Google search I doubt I would ever find some of the past-answers to a good many things myself.

Both the forum search and the support search are poor. Using the “site:” option with a search engine is usually faster and gets better results.

hello everyone ,

it’s me again, how are you doing?

i did buy a dc input for my phono recently, however..
the turntable is connected. but the result in no sound.

i could only hear thin volume from the turntable event though i’ve ajusted  the setting in the app.

any lead could give me advices please? 😭

The wiring in your images (as far as can be seen) looks correct.

What is the line-in ‘source level’ setting in the ‘Connect’ room settings in the App? If it’s set low, at level 2 - try setting it higher (level 8 or higher) and ensure the output volume is set to 50%, or higher, too.

Then go onto select the line-in icon in the Music Services Tab to play the TT audio on your chosen Sonos device/group and ensure the volume-level for that device/group is not set low, or muted and see if that gets things working for you.

Make sure the pre-amp is working aswell - are there any signs that device is receiving power, any visible LED light etc?

Just to confirm, your cartridge is an MM Moving Magnet and not a MC Moving Coil as the preamp you have is for MM only from what I can see.

You could check to see if it has an MM / MC switch though.

Low and poorly equalized sound is a common issue when mixing MC cartridges and MM preamps.
