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
Rear
Front
• Right after power is turned on, confirm that the voltage across
the terminals of R1303 (SURROUND BACK R ch), R1153
(SURROUND R ch), R1154 (FRONT R ch), R1152 (CEN-
TER), R1150 (FRONT L ch), R1151 (SURROUND L ch),
R1149 (SURROUND BACK L ch) are between 0.1 mV and
10.0 mV.
• If measured voltage exceeds 10.0 mV, open (cut off)
R1252 (SURROUND BACK R ch), R1112 (SURROUND R
ch), R1114 (FRONT R ch), R1110 (CENTER), R1106
(FRONT L ch), R1108 (SURROUND L ch), R1104 (SUR-
ROUND BACK L ch) and reconfirm the voltage.
Attention
If the measured voltage exceeds 10.0 mV after repair-
ing a power amplifier first check for a defective compo-
nent before cutting the bias resistor.
• Confirm that the voltage is 0.2 mV to 15.0 mV after 60
minutes.
● 電源投入直後、R1303(SURROUND BACK R ch)、
R1153(SURROUND R ch)、R1154(FRONT R ch)、
R1152(CENTER)、R1150(FRONT L ch)、R1151
(SURROUND L ch)
、R1149
(SURROUND BACK L ch)
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10.0 mVを超えている場合は、R1252

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10.0 mV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。
