Purpose:
Function:
Effect:
Wave Correction Processor
Reduces the non-linear distortion of the
transistors in the power stage.
Corrects the signal to the power stage in
advance.
Reduces the distortion by 20-40 dB more
than the conventional processor. Thus,
this amplifier can be said to be the non-
feedback amplifier.
\
New Super A IC
Newly developed monolithic IC exclusive
for Dynamic Super A which improves fur-
ther the current linearity and high-speed
response ability as compared with the
conventional Super A IC.

(2) ‘‘Dynamic Super A’’ Circuit
Operation
Isolate Drive Circuit
This circuit is basically an FET source-follower circuit.
In A-X55, adequate dielectric strength is assured by the
cascode connection between 0501 2SK170 (BL, V)
and Q505.
Q503 is aconstant current circuit which determines the
current flowing in zener diode D509 RD2.7EB2 which
determines the cascode voltage of 0501 and Q505.
Q507 is aconstant current circuit which determines the
current flowing in Q501.
2. Wave Correction Processor Circuit
This circuit decreases the non-linear distortion in the
power stage. It converts into a current the non-linear
distortion voltage detected by emitters of Q515
2SC2240 (GR, BL) and 0517 2SA970 (GR, BL). This
conversion current is applied across R509 (270) to the
input signal in anti-phase to deny the distortion.
Thus, the distortion is reduced by 20-40 dB.
. New Super A IC
The basic operation of this IC is the same as that of the
conventional Super A IC. This new Super A IC is a
monolithic IC exclusive for Dynamic Super A with fur-
ther improved current linearity and faster response.,

Procedures
Drive Amp. (TXX- 373) Center Voltage Adjustment
6-(1) Drive Amp. Center Voltage
Adjustment
1. Before turning on the power, set the semi-fixed resistors
(R311 for Left channel and R312 for Right channel) of
the drive amplifier circuit board (TXX-373) to the center
position.
. Adjust the semi-fixed resistors (R311 and R312) so that
the voltage at the following test points of the power
amplifier circuit board (TXX-374) is within a range of
+10OmV or less five minutes after the power is turned
on.
Left
channel:
Measure
the
voltage
between
test
point
@)
and
test
point
@®
(ground).
Right
channel:
Measure
the
voltage
between
test
point
and test point @® (ground).
The measurements can also be performed at the
speaker terminals if the relay is operating normally.

channel) of the power amplifier circuit board fully
counterclockwise.
. Adjust the semi-fixed resistors (R521 and R522) so that-
the voltage at the following test points of the power
amplifier circuit board is within a range of 9MV ~ 13mV
after the power is turned on.
Left channel: Measure the voltage between test
point @ (emitter of 0523) and output
at the test point
Right channel:Measure the voltage between test
point @) (emitter of Q524) and output
at the test point
. Readjust resistors R521 and R522 about five minutes
after the power is turned on (the heat-sink temperature
must be sufficiently high) so that the voltage at the test
points becomes 11mV. Confirm that the voltage does
not vary when the heat-sink temperature increases fur-
ther.
Note: Be sure to perform the measurement with the
probes and cabinet of the measuring equipment
separated from the grounding terminals of A-X55 or of
other measuring equipment.
