PolarChoice 系列 PC Desktop-18RD 多模式桌面麦克风，带自动混音逻辑

Logic Signals - If the PC desktop mic is in momentary mode (see above section on the mute switch), the logic level on the white wire will normally be "high", and go "low" when the push-button is pressed. If the mute switch is set for toggle mode, the logic will toggle from high to low, or from low to high, each time the button is pressed. (If desired, a pc board change can be done to force the logic to always be momentary, regardless of switch settings. See Figure 3).
逻辑信号 - 如果 PC 桌面麦克风处于瞬时模式（请参阅静音开关上面的部分），白线上的逻辑电平通常为“高”，当按下按钮时会变为“低”。如果静音开关设置为切换模式，则逻辑将在每次按下按钮时从高变为低，或从低变为高。（如果需要，可以进行 PC 板更改以强制逻辑始终为瞬时，而不考虑开关设置。请参见图 3）。
