产品描述
详细介绍：
234XL高精密电子分频器，均设有高通滤波器，切除无用的低频干扰，保护扬声器不易被烧毁，相位切换开关，高低频独立增益调节，更方便各种不同系统的连接使用。234XL是一款立体声3分频+2路超重低音，陡度为12dB/倍频程的分频网络。独立的超重低音输出可将低音左及右声道混合而成，从而增强低音的力度表现。
技术参数
TRS或XLR差分平衡输入和输出
可选择立体声或由左右声道相加而合成的超低音
两通道均有x10范围选开关
两个通道均有40Hz高通滤波器(底频切除)
所有的输出均带相位反转开关
所以频段上的输出电平均可独立调整
24dB/oct Linkwitz-Riley滤波器（专业标准）
立体声/单声道状态指示LED灯，表明单元所选择的工作模式。

Low cut Switch Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel.
Phase Invert Switch Inverts the phase at the output, one switch per output.
x1 / x10 Switch Multiplies the low-high(mono: low/mid and high/mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel.
Mode Switch Selects stereo 2-way or mono 3-way operation and disables all LEDs for controls that are non-functional in the selected mode.
LF Sum Switch Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2�s low output phase invert LED to indicate that this output is not operational in the LF sum mode.
