●
Right after power is turned on, confirm that the voltage
across the terminals of R1152 (SURROUND BACK
Rch), R115 4 (SUR ROUN D Rch), R115 0 (FRONT
Rch), R1148 (CENTER), R1149 (FRONT Lch), R1153
(SURROUND Lch), R1151 (SURROUND BACK Lch)
are between 0.1mV and 10.0mV.
●
If it exceeds 10.0 mV, open (cut off) R1090 (SURROUND
BACK Rch), R1092 (SURROUND Rch), R1088 (FRONT
Rch), R1086 (CENTER), R1087 (FRONT Lch), R1091
(SURROUND Lch), R1089 (SURROUND BACK Lch)
and reconfirm the voltage.
Attention
If the measured voltage exceeds 10.0mV after an
amplifier repair, first check for a defective component
before cutting the bias resistor.
●
Confirm that the voltage is 0.2 mV to 15.0 mV after 60
minutes.

CONFIRMATION OF IDLING CURRENT OF AMP UNIT /
アンプユニットのアイドリング電流の確認
● 電源投入直後、R1152 (SURROUND BACK Rch)、R1154
(SUR R O UND Rch)、R1150 (FR O N T Rch)、R1148
(CENTER)、R1149 (FRONT Lch)、R1153 (SURROUND
Lch)、R1151 (SURROUND BACK Lch)の端子間電圧を
測定し、0.1 mV から 10.0 mV の間であることを確認して
ください。
● 電圧が 10 mV を超えている場合は、R1090 (SURROUND
BACK Rch)、R1092 (SURROUND Rch)、R1088 (FRONT
Rch)、R1086 (CENTER)、R1087 (FRONT Lch)、R1091
(SURROUND Lch)、R1089 (SURROUND BACK Lch)を
カットし、電圧を再確認してください。
注意
パワーアンプ修理後に 10.0mV を超えている場合は、抵
抗をカットする前に故障箇所を調べてください。
● 60 分後、電圧が 0.2 mV 〜 15.0 mV であることを確認し
てください。
