In the cage of live recording by micro phones, however, the peak level is Usually very high, and further itis not audibly equivalent to the actual sound level. Thus, when you are too sensitive about clipping at the peak, the average level is apt to be set rather low, thus inducing deterioration of the signal-to noise ratio. Therefore, to realize good live recording using microphone, it is important to attend to such opportuni ty as much as possible, and get your ‘own auditory feeling to what extent such clipping is allowed The K-6 features the bias fine control within #10% from the peak bias point, This is because the change of the bias current provides a subtle difference in tonal quality, For in. stance, at the “under-bias” point the treble response is extended, while at the “overbias” point the bass. distor tion is improved, Naturally, within the range of this fine-tune control no dete- rloration takes place in any character istics, Make free selection of your favorite point to augment your ples: sure of recording [At the time of playback of cassette tape, set the EQ Selector Switch (18) to an appropriate position according to the ist specifying the kinds of tapes.
