RX-V465/HTR-6240/AX-V465
DC/TH
DC:
Power amplifier DC (DC voltage) output is
detected.
Normal value:
TH:
Temperature on the heat sink is detected.
Normal value:
If DC and TH are out of the normal value
*
range, the protection function works to turn
off the power.
IMP/PL
IMP:
8 or 6 ohms impedance setup detection
IMP 8:
IMP 6:
PL:
PLDET (Power amplifier output voltage detection)
The power amplifier output voltage is detected
and the power amplifier input voltage is controlled
according to the detected output voltage.

DC/TH
DC:
パワーアンプ DC(直流電圧)出力の検出
正常値:
23 ∼ 70
(基準電圧:3.3 V = 255)
TH:
ヒートシンク温度の検出
正常値:
0 ∼ 124
(基準電圧:3.3 V = 255)
※ DC および TH は正常値を外れるとプロテク
ションが働き、電源が切れます。
