Beocenter 7700 recordplayer sound.

I have a beocenter 7700, radio sounds great!

Tape sound like ... a tape sounds.

But the recordplayer i think sounds a little weak compared to the radio. Softer, weaker, less bass...

Is that normal?

I triend a new smmc4 and a new mmc4, not much of a difference though.

Has anyone had the same experience/ problem and if so how can i fix this?
