Description of External Components
.
C1 (1.0 to 10 F):
VREF amplifier is referenced to this decoupling capacitor.
The VREF SVRR depends on the value of this capacitor.
Note that if the capacitance is reduced, the SVRR worsens.
.
C2,C10:
Playback preamplifier EQ constant.
.
C3,C9 (0.47 to 3.3 F):
Preamplifier output capacitor.
.
C4,C8:
AMSS input HPF capacitor.
.
C5,C7:
EQ constant for metal (built-in resistance 3.9 k
±15%).
.
C6 (0.1 to 22 F):
VREF decoupling capacitor.
For high-frequency noise rejection.
.
C11,C12 (3.3 to 10 F):
NFC decoupling capacitor.
Note that if the capacitance is reduced, the preamplifier low-frequency gain decreases.
.
C13,C15 (1.0 to 3.3 F):
Power amplifier input capacitor (Input resistance: 10 k
).
.
C14,C17:
Capacitor for low boost LPF.
The low boost gain depends on the capacitance.
.
C16 (1.0 to 4.7 F):
Boost amplifier NF capacitator.
Note that if the capacitance is reduced, the low boost low-frequency gain decreases.
.
C18,C23,C26 (0.1 to 1.0 F):
Oscillation blocking capacitator.
.
C19,C22,C25 (3.3 to 10 F):
Power amplifier NF capacitor.
Note that if the capacitance is reduced, the power amplifier low-frequency gain decreases.
.
C20,C24:
Bass high boost capacitor.
The high gain depends on the capacitance.
.
C21 (100 to 2200 pF):
Oscillation blocking capacitator.
.
C29 (4.7 to 10 F):
RF output decoupling capacitor. (Also serves as the power supply capacitor and the
oscillation blocking capacitor.)
.
C28 (22 to 220 F):
Power supply capacitor.
.
C30 (2.2 to 10 F):
RF is referenced to this LPF capacitor.
The RF SVRR depends on the capacitance.
.
C31,C32 (0.047 to 0.22 F):
Switching circuit smoothing capacitor. Must be adjusted according to the set timing.
.
R1,R10:
For preamplifier gain adjustment.
.
R2,R9:
Playback preamplifier EQ constant.
.
R3,R8:
EQ constant for metal.
.
R4,R7:10 k volume control.
.
R5,R6:
For AMSS gain adjustment and HPF.
.
R11,R12,R13:
For oscillation blocking.
.
R14,R15 (100 to 430 k):
For switching circuit smoothing (discharge resistors).
