TESTING
PROCEDURES

Classé - 14
INPUT PCB
A. INSPECTION
-visually check all parts for: solder bridges or splashes, backwards or
missing component orientation.
B. POWER SUPPLY VOLTAGES
1. CR105-21V
2. CR102+21
3. CR302-5V
4. CR301+5V
5. CR104-12V
6. CR103+12V
7. R305-12V
8. R301+12V
9. C202+5V
C. DAC OFFSETS CALIBRATION
-maximum 6mV
1. Measure DC voltage of J404A to J404B LGND.
Divide 5127 by this number choose the closest factory select resistor value in K
OHMS for 311 (if neg.) on R 313 (if pos.).
2. Measure DC voltage of J403A to J403B RGND.
Divide 5127 by this number and choose the closest factory select resistor value
in K OHMS for R 306 (if neg.) or R 308 (if pos.).
D. CHECK ANALOG AUDIO OUTPUT SIGNAL
