D C P R T : x x x H
Cause:
DC output of the power amplifier is abnormal.
Supplementary information:
The protection function
worked due to a DC voltage appearing at the speaker
terminal. A cause could be a defect in the amplifier.
Turning on the power without correcting the abnormality
will cause the protection function to work in 3 seconds
and the power supply will be shut off.
2-2. When the protection function worked due to a
short between speaker terminals.
2-3. When the protection function worked due to
abnormal DC output.
Cause:
The line between speaker terminals is shorted.
Supplementary information:
As the excess current is
detected after operation of the speaker relay, the shorted
speaker terminal and the connected speaker can be
identified.
Turning on the power without correcting the abnormality
will cause the protection function to work immediately and
the power supply will instantly be shut off.

2-2. スピーカー端子間のショートによりプロテク
ションが働いた場合
2-3. DC 出力異常によりプロテクションが働いた場合
原因:
スピーカー端子間がショートしている。
補足:
スピーカーリレー動作後に過電流を検出している
ので、スピーカー端子および接続しているスピー
カーのショートが特定できます。
異常状態のまま電源を入れると、瞬時にプロテクション
が働き、すぐに電源が切れます。
原因:
パワーアンプの DC 出力が異常。
補足:
アンプの故障でスピーカー端子に直流電圧が DC
掛かるなどが原因で、プロテクションが働いたこ
とを示します。
異常状態のまま電源を入れると、3 秒後にプロテクション
が働き、電源が切れます。
