POWER AMPLIFIER ADJUSTMENT /
パワーアンプ調整
1. Right after power is turned on, confirm that the
voltage across the terminals of R22
49
(SURROUND
Lch), R22
5
2 (FRONT Rch), R22
5
3 (CENTER), R22
54
(SURROUND Rch) and R22
55
(FRONT Lch) are within
the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R2207
(SURROUND Lch), R2210 (FRONT Rch), R2211
(CENTER), R2212 (SURROUND Rch) and R2213
(FRONT Lch), and then reconfirm the voltage.
Attention
If the measured voltage exceeds 10 mV after repairing
the power amplifier, check other parts again for any
possible defect before removing the resistor.
3. Confirm that the voltage is within the confines of
0.2 mV to 1
5
mV after
6
0 minutes.

注意
パワーアンプ修理後に
10 mV
を超えている場合は、
抵抗を外す前に故障箇所を調べてください。
