However, there are also turntables with built-in
pre-equalizers! You can then connect these directly to the line inputs. But most high-end users will certainly use a good turntable and cartridge that does not have integrated phono preamplification and will use a separate phono preamplifier, which must then of course be connected to the line inputs of the 520.
Well, you’ve done it and can now enjoy your vinyl.
