Right after power is turned on, confirm that the voltage
across the terminals of R1303 (SURROUNDBACK
Rch), R1153 (SURROUNDRch), R1154 (FRONT Rch),
R1152 (CENTER), R1150 (FRONT Lch), R1151 (SUR-

tween 0.1mV and 10.0mV.
If it exceeds 10.0mV, open (cut off) R1252 (SURROUND

and reconfirm the voltage.
Attention
If the measured voltage exceeds 10.0mV after an am-
plifier repair, first check for a defective component be-
fore cutting the bias resistor.
Confirm that the voltage is 0.2 mV to 15.0 mV after 60
minutes.
