The GT1200 added a pad and a low-pass filter on the basis of the former GT1100. You shall reduce distortion form high sound pressure levels and eliminate unnecessary low-end frequencies. It has a tall shape. There're nine different polar patterns remotely selectable on power supply for ultimate versatility in use and ease of operation: omni-directional, cardioid, figure 8，and six intermediate stages. Its tube preamplifier circuitry uses the replaceable classic 12AX7 vacuum tube, the same extraordinary sound and performance of a legendary vacuum tube microphone. The GT1200 is an ideal microphone for the concert halls and stages.
