三向有源 / 双向有源开关

双向有源:“全幅” LF 输入接到引脚 1+ 和 1-,-6dB/ 八度音黑斑补偿网络接到其 中的一个使用低频选择开关 (上面)的 LF 换频器。

三向有源:不使用黑斑补偿网络 (黑斑补偿必须由上行信号处理提供)。将全幅输入 信号接入引脚 1+ 和 1-,将已补偿 (处理)的信号接入引脚 2+ 和 2-。要改变已补 偿换频器的位置,使用低频选择开关或更改信号处理。三向模式的默认低频选择开关 位置为 A ;如果放在 B 处,和 LF 换频器 A 和 B 的连接 (根据表 1)就互换了。

低频选择开关

WideLine 为三向设计 (已补偿、未补偿和高频),补偿由无源网络 (双向模式)或 上行信号处理 (DSP) (三向模式)提供。这样无需更改音箱就可以选择使用 “左机 罩”或 “右机罩”。

双向模式:通过插入一个 -6dB/ 八度网,补偿开关可以将任一低频换频器当作已补偿 单元进行选择 (仅低音)。开关把手指向未补偿的 (全幅)低频换频器一侧。

CH

三向模式:内部的 -6dB/ 八度网应用到任一 LF 换频器上。由信号处理来实现补 偿。只有在全幅信号应用到引脚 1+ 和 1- 以及已补偿信号应用到引脚 2+ 和 2- 的 时候,开关把手才指向未补偿的 (全幅)低频换频器一侧。三向模式的默认位置在 A ;如果放在 B 处,和 LF 换频器 A 和 B 的连接就互换了。
