off-axis feedback的意思|示意

Both models feature super cardioid patterns for high gain before feedback and increased rejection of off axis sound.

这两种型号均采用了前反馈和健全的离轴增加抑制高增益超心形图案。

The cardioid pickup pattern minimizes annoying feedback when used close to sound reinforcement speakers and monitors, while reducing the pickup of unwanted off axis sounds.

最小的心形拾音模式使用时，恼人的反馈接近扩声音箱和显示器，同时减少不必要的离轴声音回升。

The DM6.0 is extremely sensitive as it employs a tight Supercardioid pickup pattern to reduce feedback and provides over 26dB of off axis feedback rejection.

The DM6.0规定为26dB，是极为敏感，因为它采用了严格超心形拾音模式，以减少对反馈和反馈的离轴规定为26dB拒绝。
