CIRCUIT DESCRIPTION
[Expander Circuit]
The expander circuit has been designed to expand the range of audio. Specifically, it inputs a signal with variation over 10 dB and outputs a signal with variation over 20 dB. In other words, the expander circuit can make loud sound louder and small sound smaller. Its characteristic is as shown in Figure 1, which shows its characteristic (B) in comparison with the characteristic of an ordinary amp (A).
Figure 2 shows the characteristics of the expander amp used in this set. It shows that the effect described above is applied in the same way all over the bandwidth

Appendix
IC4 block diagram is as shown in Figure 3.
The point in incorporating an expander circuit in this set is to make the audio more powerful, with punch in it. The expander amp used in the set outputs similar audio to ordinary amp when the input level is low, while it can provide powerful audio with punch when the input level is above a certain level.
