[Expander Circuit]

The expander circuit has been designed to expandthe range of audio.Specifically, it inputs a signal with variation over 10dB and outputs a signal with variation over 20 dB.In other words, the expander circuit can make loudsound louder and small sound smaller.Its characteristic is as shown in Figure 1, whichshows its characteristic (B) in comparison with thecharacteristic of an ordinary amp (A).

(A) Characteristic of ordinary amp(B) Characteristic of expander(C) Characteristic of expander amp used in the set

The point in incorporating an expander circuit in thisset is to make the audio more powerful, with punch init.The expander amp used in the set outputs similaraudio to ordinary amp when the input level is low,while it can provide powerful audio with punch whenthe input level is above a certain level.

Figure 2 shows the characteristics of the expanderamp used in this set.It shows that the effect described above is applied inthe same way all over the bandwidth

AppendixIC4 block diagram is as shown in Figure 3.
