Stone Circle Sound is a division of Portal Production that provides live sound support (that is, PA) for musicians.  We can provide sound system support and live audio engineering for acts ranging from the solo acoustic singer/songwriter to larger groups such as rock bands or groups with horns or multiple vocalists.  We use Mackie and Yamaha mixing boards, JBL monitors and speakers, and Shure and Sennheiser microphones.  Contact us to discuss your needs.
