The Roland PM-100 E-Drum Monitor is a powerful monitor box, especially developed for Roland V-Drum sets. With 80 watts of power, a 10" subwoofer and 2" tweeters, the Roland PM-100 is the ideal E-Drum monitor for home and small gigs with the E-Drum Set. It has two jack inputs, one for the E-Drum set and another line in, where an additional sound source can be connected. E-Drums and Line In can be adjusted independently of each other in volume by two separate rotary switches. Furthermore, there is an equalizer on board with which bass and treble can be regulated.
