This is called a phono-level signal, which is much quieter than other audio sources like CD players or streaming devices.
It also uses a specific equalization curve called the RIAA EQ that needs to be corrected for accurate sound.
The unit has a dedicated phono input that:
Amplifies the signal to line level.
Applies RIAA equalization to make the sound natural and balanced.
You just plug your turntable into the "PHONO" jack, and you’re good to go — no extra gear needed.
