● Short detection circuit between SP+ and SP- terminals
If the SP+ and SP- terminals are shorted in the vicinity of the
terminals, the self oscillation occurs in the D-class amplifier.
The oscillation in opposite phase is caused between the +
and - terminals of the BTL, and this oscillation is applied to the
differential amplifier, IC22 (2/2) to limit the amplitude with the
zener diodes such that the voltage does not exceed the with-
stand voltage.
The output from pin 7 of IC22 is rectified through the band
pass filter whose center frequency is about 3kHz.
The DC voltage generated after the rectification is applied to
the comparator, (IC6 (2/2)) and generates “L” at pin 7 of IC6
when the voltage exceeds the preset threshold.
●Power supply circuit for FL
• V-FL
V-FL is the power supply for grid of FL. D48 is used to select
either the battery or +15V power supply that has higher volt-
age.
The power supply voltage is set to constant 13V in D49.The
power is turned ON/OFF with Q54 and is applied to FL driver.
• FIL+
Power is supplied by the battery and the voltage is set to 2.3V
in D49 so that it is applied to the filament of FL.
The power is turned ON/OFF in Q48 in response to the FL-
ON signal from the µ-com.
●Ground fault detection circuit
When SP+ or SP- output terminal is shorted to the ground,
the current running in the +B power supply and that in the -B
power supply are unbalanced.
The current unbalance (±) is measured by R203 and R204
and the currents are mixed in R225.
When the currents become out of balance due to the above
shorting to the ground, the voltage is caused across R225.
When this voltage exceeds the threshold decided by R256
and R257, the “L” output is generated at pin 7 of IC7.
As a result, the over current protection operation is activated.

PULSE SHAPING
CIRCUIT
OUT
IN
●Pulse shaping circuit
When either output from the ASO detec-
tion (IC6-pin 1), ground fault detection
(IC7-pin 7) or short detection (IC6-pin 7)
is “L”, the pulse with a constant width of
about 10msec is generated even if the
input pulse width is small.The input to
the pulse shaping circuit is pin 5 of IC17
and the output from the circuit is pin 3 of
IC17.
●Servo circuit
Amplifies DC offset voltage that is output to SP+
terminal in IC19 (2/2).
Feedbacks the output from pin 7 of IC19 to the tri-
angular wave generation circuit.
Corrects DC offset voltage at SP+ terminal towards
0V by incorporating the feedback in the triangular
waves that are applied at pin 6 of IC14.
●LIMIT circuit
IC24 (1/2) is a voltage follower and IC24 (2/2) is a reverse
amplifier that has no gain.
Q39 is turned ON/OFF in response to H/ L of LIMIT (pin
63) from the µ-com.
Voltage at pin 3 of IC24 becomes 2.2V and 5V in response
to ON/OFF of Q39.
When the u-com detects 1Ωload, the input signal is clamped
at ±2.8V, in which 0.6V of vf from D205 and D206 is added,
and peak value of the signal is limited.
●NF circuit
Differentially amplifies the signal in IC13 (1/2) for the BTL out-
put and applies negative feedback signal to pin 6 of IC13 (2/
2).
