C
mixing
The recommended value is 100pF. If the value of the ca-
pacitors is too small, oscillation and RF noise due to
strong RF signals can degrade circuit performance. If the
value of the capacitors is too large, the audio frequency
characteristics will deteriorate.
C
The recommended value is 47 F. The startup time after
power is applied is related to the value of this capacitor.
If the value of the capacitors is too small, transient noise
when power is applied will be large.
