Audio-Technica AT-LP 120 USB Turntable Background Noise

Hello,

I just bought my first vinyl player (Audio-Technica AT-LP 120 USB). It is connected to a Yamaha RN 301 amplifier + Yamaha CDS 300 CD player (preamp, so no phono input). During playback, I noticed background noise as soon as I raised the volume a bit, but nothing when listening "quietly". I removed the cartridge, put it back on, adjusted the anti-skating, the tracking force of the arm, and reconnected my speakers, but nothing works... the noise is still there, like an electrical tension noise. Have you ever encountered this issue?

Thanks in advance.

    This humming may be due to a bad ground, check:
    The ground wires of the cell (green and blue)
    The RCA cables, they may be poorly shielded, or change them for better quality;

    Before that, try connecting the chassis of the turntable to that of the amplifier with a wire
    I call a spade a spade *

      I tried with several vinyls to see if the problem was there (you never know...) and the same issue persists. I checked the ground wires as you advised me, nothing unusual, but the turntable is new... No problems with CD or USB... Thankfully, I have the famous RCA Monstercable in stock that I used with my home theater, but the issue is that the RCA output of the turntable is inside (plastic casing) and I don't really see how to replace it (I am really a novice in this area).
