Your Sanyo thing has a phono preamp built-in. Grounding is sorted there too.
If you plug a phono signal directly into a line input, you'll hear NO bass. Try it, youl'll see what I mean.
The reason it works this way because you can't really press that much bass into a record (the stylus would be all over the place). So when they made a standard for records/turntables, they made a standard EQ curve (RIAA curve) that boosts the bass back up. A phono preamp, like those in your DJ mixer, provides that EQ curve. It's built in on some turntables, all DJ mixers, and most hi-fi amps. You can also buy seperate units, including audiophile models that cost as much as a car.
