5-Pin Female Din to RCA 4 Cable Adapter for Turntable

Hello everyone,

I have an old turntable from the 70s that I want to connect to a newer amplifier. To do this, I need a female DIN to male RCA adapter.

The seller at a connectivity shop sold me a cable of this type (he didn't have a model with only two audio RCA):

He assured me that there would be no issue in not connecting the two video cables (yellow and black) and that the performance would be just as good as with a double RCA adapter solely for audio. I have some doubts and wonder if having all 4 cables could lead to a loss/reduction of the electrical signal and therefore sound quality?

I would prefer to get the community's opinion before opening the package so I can return the cable.

Thank you in advance!
