While a track is playing, press the "In" button to mark a loop start, then "Out" to mark the end. The manual clarifies that the loop length is shown on the LCD in beats (1/4, 1/2, 1, 2, 4, 8). Press "Reloop" to restart the loop.

A: No. The rear "Line Out" is a fixed-level output meant for recording, not a sub-out. You would need an external active crossover. edison professional scratch 2500 dj system manual
