The Rolls PM50se is a unique monitoring solution. It includes through XLR jacks, 2 headphone output jacks, and a 1/4" monitor input jack.

The PM50se has the exactly same features as the PM50s, but with some new updates. We added a mic / line switch for the XLR input, and replaced the jumpers with switches for both the ground - lift and stereo - mono selection.
