A:AnswerHello, the Denon DP-300F has a built-in phono EQ making it compatible with systems with RCA analog inputs. RCA to 3.5mm adapters may also be used.
A:AnswerI believe it is under the platter - you select it's position before sliding the platter down on the spindle and slipping the belt over the drive capstain. (They make it easy with a piece of plastic under the belt to pull it gently away from the underside of the platter while keeping it free of contaminants from your skin).
A:AnswerDirect drive has the motor mounted directly to the platter that spins. belt drive has a belt that goes from the motor to the patter to make it spin.
Direct drive tends to add a rumble to the recording were a belt drive is quieter. Direct drive is mostly for DJ's.
