Confirmation of Idling Current of Amp
Unit
• Right after power is turned on, confirm that the voltage
across the terminals of R319 (MAIN Lch), R320 (MAIN
Rch), R325 (CENTER), R326 (SURROUND Lch),
R327 (SURROUND Rch), R321 (SURROUND BACK
Lch), R322 (SURROUND BACK Rch) are between
0.1mV and 10.0mV.
• If it exceeds 10.0mV, open (cutoff) R291 (MAIN Lch),
R292 (MAIN Rch), R295 (CENTER), R296
(SURROUND Lch), R297 (SURROUND Rch), R293
(SURROUND BACK Lch), R294 (SURROUND BACK
Rch) and reconfirm the voltage.
Attention
If the idle current 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 ~ 15.0 mV after 60
minutes.
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、R319 (MAIN Lch)、R320 (MAIN
Rch)、R325 (CENTER)、R326 (SURROUND
Lch)、R327 (SURROUND Rch)、R321
(SURROUND BACK Lch)、R322 (SURROUND
BACK Rch)の端子間電圧を測定し、0.1mVから
10.0mVの間であることを確認してください。
● 電圧が10mVを超えている場合は、R291 (MAIN
Lch)、R292 (MAIN Rch)、R295 (CENTER)、R296
(SURROUND Lch)、R297 (SURROUND Rch)、
R293 (SURROUND BACK Lch)、R294
(SURROUND BACK Rch)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0.2mV〜15.0mVであることを確認して
ください。
