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 R2152 (SURROUND Rch), R2149
(FRONT Rch), R2151 (CENTER), R2150 (FRONT Lch)
and R2153 (SURROUND Lch) are within the confines of
0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R2107
(SURROUND Rch), R2111 (FRONT Rch), R2110
(CENTER), R2109 (FRONT Lch) and R2112 (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、R2152(SURROUND Rch)、R2149(FRONT
Rch)、R2151(CENTER)、R2150(FRONT Lch)、R2153
(SURROUND Lch)の端子間電圧を測定し、0.1 mV から
10 mV 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、R2107(SURROUND
Rch)、R2111 (FRONT Rch)、R2110(CENTER)、R2109
(FRONT Lch)、R2112(SURROUND Lch)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。
3. 60 分後、電圧が 0.2 mV 〜 15 mV であることを確認して
ください。
