At under $1000 the Yamaha EMX512c is the biggest price breakthrough in PA we've ever seen! A solid 500 watts and with an SPX 24 bit reverb chip PLUS feed-back locators on all vocal inputs this lightweight head is no toy! It is a serious fully integrated mixer offering maximum quality and creative control. The ultra lightweight amplifier circuits mean the total weight is just 10kg. Connections include XLR, TRS 1/4in. phone, and RCA. A power mode switch allows the two amplifier channels to be used with the stereo outputs, drive main speakers and separate monitor mixes, while power amp mode selector switches allow the user to configure the amp channels to suit a range of applications. Amazing!
