QSC CX204V, CX302V, CX602V Manual - Comprehensive Stereo Amplifier Guide

数据埠	四通道放大器上的数据埠。

双通道型号有一个数据埠，四通道型号有两个数据埠（一个用于通道 1-2，另一个用于通道 3-4）。数据埠连接到选配的 QSC 附件和处理设备。数据埠设备提供远程待机控制、监控、 DSP 处理、滤波器和分频功能。CX 的数据埠支持全部 “V1” 数据埠功能。双通道型号支持直接装载的 DSP " 模块 "。四通道型号要求对用数据埠电缆连接的附属模块进行远程装载。

各数据埠连到其各自的通道对：通道 1-2 或 3-4。每个通道对可使用其数据埠或接线盒输入。使用数据埠时，不要连接该通道的接线盒输入。放大器待机只受通道 1- 2 数据埠控制。

数据埠技巧：

1- 数据埠 1-2 控制整个放大器的待机情况。在数据埠可以控制电源之前，交流电开关必须置于开。

2- 各数据埠控制并监视输到各自通道对（通道 1-2 或 3-4）的信号。

3- 在使用数据埠输入时，不要用单桥式或并行模式开关。信号级会降低。要了解更多信息，参见数据埠设备所有者手册。

4- 数据埠设备通常用于控制输入放大器前的信号增益。确认操作无误后，将前面板增益控制设为最大。如果需要，安装防护罩，防止未经授权的修改。

5- 每一通道使用单独的内部散热片。通道对的数据埠显示散热片的温度。

6- 咨询您的 QSC 经销商或 QSC 网站了解最新的数据埠产品。

输入端

每一通道都有一个平衡的 3 引脚接线盒输入端。双通道型号也具有 XLR 输入。输入阻抗为 12k 欧姆（平衡）

或 6k 欧姆（非平衡）。包装箱装有一套接线盒连接器。可用简单的手工工具连接接线盒，可快速进行输入更改。XLR 输入端皆以标准电缆连接并可快速更换。引出线在后面板上标出。

建议采用平衡连接以降低交流噪声和干扰，特别在使用长电缆的情况下。非平衡连接适用于短电缆的情况。信号的源阻抗应低于 600 欧姆。如果数据埠正在用于输入信号，不要连线到接线盒。

接线盒连接器

平衡输入：将线剥去 1/4 英寸 (6 mm)，连接到连接器上，如图所示。拧紧螺丝。

非平衡输入：将线剥去 1/4 英寸 (6 mm)，连接到连接器上，如图所示。中间的引脚必须连接到屏蔽引脚上，如图所示。拧紧螺丝。

XLR 输入 ( 仅限双通道型号）

平衡输入：如图所示连到插头。

非平衡输入：如图所示连到插头。引脚 3 和引脚 1 必须用跳线连接，如图所示。

CX302, CX1202V, CX502, CX702, CX1102 specifications

QSC Audio has established itself as a leader in professional audio solutions, and their CX series amplifiers, including the CX204V, CX254, and CX404, stand out for their performance and versatility.
