Help me with gain issue from hub

I have a Bluesound hub and a node2, I have bought a record player and connected it in the phono input of the hub, node2 has full volume, when selecting phono in the app, the volume is approx 20-25 dB lower than when streaming qobuz, can I fix this, would a riaa with adjustable gain solve the issue or would the bluos system just lower the gain, node 2 is connected to Lyngdorf 2x400w 4ohm system via coaxial but I am simply not able to listen to loud music from a record

    Hi Lennart

    When running a phone pre-amp hooked up correctly you should be able to hear vinyl but at much quieter volumes due to how vinyl is recorded. For example, I have a circa 1993 Technics turntable connected to that same Blueosund HUB shared with an NAD m10vs (I hear NAD makes good stuff) in my home. Listening to TIDAL, my volume slider is at about 1/3 volume. If I am listening to Vinyl the same recording will be at about 60%. If your Phone Preamp has gain settings, you can try tweaking those.

    Unfortunately, that's just the way RIAA works. Wikipedia actually does a great job of explaining why in great detail; https://en.wikipedia.org/wiki/RIAA_equalization

    The hole problem is that the pre amp is the one build in the Bluesound hub and it can't be adjusted, I have actually solved the problem by buying a pre amp and then use the standard analogue input on the hub, but that was not my intention when I bought the hub, in the first place

    I can confirm. I have just been comparing two different turntables, alternately connected through a Schiit Mani phono pre-amp to an NAD C700 or to a Bluesound Hub streaming to the same NAD C700. The volume level through the Bluesound Hub is markedly lower than through the Schiit Mani. Like, maybe half the volume or lower. I thought at first my turntable was failing it was so quiet, which is why I started experimenting with another turntable and with a separate phono pre-amp. The Bluesound Hub is unacceptably low volume. It's not a question of whether the turntable has a pre-amp or not. It's that the pre-amp in the Hub barely does anything at all.
