Technics SJ-MD150



Nearly identical to its predecessor SJMD 100 . The difference is that the Technics SJ-MD150 is equipped with the HDES (High Density Encoding System, Panasonic IC MN66616ZRA4), a newly developed proprietary audio compression technology (= newer ATRAC version). This circuit realizes compression of high-quality music signals by assigning bits to the frequency band that is optimal for audibility, reducing preecho noise by dividing the time axis into optimal segments, and reducing quantization noise by using a new quantization method.
