8. Measure the audio voltages at the following test points on the digital
board:
balanced line out IC1020 pin 1
IC1026 pin 1
unbalanced line out IC1005 pin 1
IC1026 pin 7.
Both voltages should be approximately 1V
pp
. If the voltages are
greater than 1V
pp
, the digital board is faulty. Return the complete
reciter to your nearest CSO for repair or replacement. If the voltages
are 1V
pp
or less, replace the system interface board.
