    An interesting feature is the ability to smoothly adjust the input resistance level in the range from 10 to 1000 ohms when connecting the MS heads. For pickup heads with a movable magnet (MM), a fixed resistance level of 47 kOhm is set, but for them you can choose from four plug-in capacity options - 50, 150, 300 or 400 picofarads.
