Bliss! I have used a pair of these for years - plenty of punch with its 12’ woofer and 250 +50 watts RMS of power. It has two input channels, with independent volume and tone controls. Each channel  has a combined XLR (for mic) and jack (for instrument or mixer output) and one channel also has  RCA inputs (eg. stereo out from a CD player or laptop). Use a pair for a great PA system, or use a single for small gig PA, dance studios, gym, DJ work etc
