Description of External Components
C1, C4
Input capacitors
2.2 μF is recommended. f
L
can be varied by C1, C4 capacitances to adjust the
bass range.
C2
Decoupling capacitor
(ripple filter)
Amplifier on time setting
capacitor
C3
Approximately 0.6 to 0.7 second for 33 μF. Since the on time is proportional to
this capacitance, it can be set as desired by varying this capacitance. The
amplifier can implement mute operation by setting C3 to GND potential.
C5
C6, C7, C8, C9
Power supply capacitor
Oscillation blocking capacitors
Use polyester film capacitors (Mylar capacitors) with good temperature
characteristics. (R2, R3, R4, and R5 used jointly.) Since stability may be
affected slightly by the pattern layout, etc., 0.1 μF or more is recommended.
10 k
is recommended. This resistor cannot be removed.
