ALIGNMENT METHOD

AUDIO SECTION 3240PE

IMPORTANT

Speaker Impedance switch should be in 8ohm position while adjusting center volatge and idling current.

INITIAL ADJUSTMENT (No load connected)

A. CENTER VOLTAGE

1, Connect OC mill ivoltmeter to Lchannel output terminals.

2. Turn on and adjust to 0V*- 30mV with VR4Q1 (10KB). Connect DC millivoltmeter to Rchannel output terminals and

adjust VR402 to 0V+- 30mY.

B. IDLING CURRENT

1. Remove solder short across R47 1and R472.

2. Connect DC nillvoltmeter across R471 (I ohm) (output transistor’s collector resistor) and adjust VR403 (1KB)

for 26 -30mY reading on meter.

Repeat adjust with YR404 (1KB), connecting meter across R472( 1ohm)

3. leave power on for minimum .5 minutes.

FINAL ADJUSTMENT

C. CENTER VOLTAGE

1. Repeat step Aabove.

D. IDLING CURRENT

1. Repeat step 8and adjust with VR403, YR404 for 30mY reading on meter.

2. After the alignment is finished, 1ohm resistor R47 I,R472 is shorted by solder short.
