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 R136 (SURROUND
Rch), R132 (FRONT Rch), R133 (CENTER), R131
(FRONT Lch) and R135 (SURROUND Lch) are within
the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R100
(SURROUND Rch), R96 (FRONT Rch), R97 (CENTER),
R95 (FRONT Lch) and R99 (SURROUND 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 15 mV after 60 minutes.
1.
電 源 投 入 直 後、
R136
(
SURROUND Rch
)、
R132
(
FRONT Rch
)、
R133
(
CENTER
)、
R131
(
FRONT

の間であることを確認してく
ださい。
2.
電圧が
10 mV
を超えている場合は、
R100
(

)、
R96
(
FRONT Rch
)、
R97
(

)を外し、電圧を再確
認してください。
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。
