Bringing together a four-channel powered mixer, muscular 280w amp to really get the sound out, and a pair of 10" two-way speakers, the Alesis PA System In A Box lives fully up to its name as an ideal sound system for adding volume to small and medium venues. Keep the mix in line with two-band EQs on each channel plus a master three-band EQ, add a dab of arena-like echo with onboard digital delay, and plug your phone, tablet, or laptop directly in with the RCA connector to get your favorite playlist going.
