出力端間に負帰還回路を接続し、このア−ンプの出力端
にヘッドホンジャックに連動して切り換わる切換スイッ
チを接続し、ヘッドホンジャックが差し込まれたとき上
記切換スイッチを切り換えて上記負帰還回路の帰還量を
変化させることを特徴とするヘッドホン出力回路。A negative feedback circuit is connected between the input and output terminals of an amplifier that outputs speaker output and headphone output, and a switch that switches in conjunction with the headphone jack is connected to the output terminal of this amplifier, and the headphone jack is inserted. The headphone output circuit is characterized in that the amount of feedback of the negative feedback circuit is changed by switching the changeover switch when the changeover switch is applied.
