Reproduction of 1-placed record with inexpensive ordinary 2-channel stereo f Re-master 1- It is a
place. The recording waveform of one channel signal in fnG'PK is fjhl & produced by the cause as
described above, and other causes. Is due to the decrease of the level considered in the
reproduction 1 of the subchannel signal due to the top damage of the recording waveform, and
the increase in the gain and loss due to the loss S of the recording waveform, the load-to-noise
ratio of the gain and loss signal is noticeably deteriorated. Because of the adoption of the angle
fiiili universal system, the advantage of the improvement is totally lost, and it is obtained by onechannel offset hold in the form of angle modulation ?; Because high levels of miscellaneous f are
generated, as described above, the recording waveform of one channel gI or the damaged four
