Analog Troubles

I have a Pro Ject turntable rca into my Rose 250 and rca out to my Sonos play 5 speaker(aux). With the Rose volume at 99 and my Sonos app at max, I can barely hear it playing ( maybe 10% loud) .
I can stream music from Rose250 to Sonos no problem, something is being lost with analog in/out…

@Stillwater

The current connection order is
Pro Ject turntable (RCA)–> RS250 (RCA)–> Sonos play 5 speaker (aux) right?
If so, the turntable has a low sound, so you need to add a phono amplifier.

Thank you

I thought the rose 250 has a pre amp built in

@Stillwater

RS250 does not have a built-in pre-amp, but it can function as a pre-amp.
Even so, the voltage that can be amplified is weak, so you must connect a phono-amp to use it.

Thank you
