Audio Technica Vector-Aligned stereo phono cartridges feature an original design patented by Audio-Technica around the world. The key to this mechanism is the two magnetic generators arranged in the shape of a “V”. These two magnets are positioned precisely to match the positions of the left and right channels in the stereo record groove. Major benefits of the Vector-Aligned cartridge include outstanding channel separation, very low distortion and superb tracking performance.
