Commentary
Stereo power amplifier equipped with IOC mechanism.
It is equipped with an IOC (Input Output Comparator) system which is a unique distortion display mechanism.
By comparing the input and output waveforms, the IOC can detect all non-linear components such as distortion that could not be detected by conventional indicators. This further improves the S / N ratio and realizes excellent characteristics.
