It is an MC boost transformer for low impedance that is ideal for MC20, etc. with low output. It can also be matched to SPUs, etc. The thick mid-range is excellent to listen to. The input/output is 1 system, but since it can be bypassed, it is a convenient design that can be used by switching between both MM/MC (Fujisawa Yukishi)
