There are four ways to experience the CT-S1000V’s amazing sound quality at its best. First, the bass-ported stereo speaker system delivers eyebrow-raising punch and clarity throughout the entire volume range. Second, plug in a good set of headphones for personal play. Third, connect the 1/4″ line outputs to any amplifier, PA system or mixer. Fourth, push the SURROUND button, and the speakers will place you right in the middle of your music.
