注意事项  Notice

在只连接一个通道时，虽然DI200Pro将作为单声道设备工作，但是，两个通道都必须通电。以使用立体声、分离或组合模式。

Whenonly connecting one channel, DI200Pro will be single sound channel, but twochannels must be powered up.  Using  “Stereo” and “Split” or “Sum” mode.

正确操作  Proper Operation

在输入缓冲级之前 ，从平衡式XLR ,Jack Neutrik Combo A系列连接器或非平衡式RCA连接器提供每个输入通道的声源。

     如上所述，“Left（左）”和“Right（右）”输入可以组合到两个输出，“Left（左）”输入可以分离为“Left（左）”和“Right（右）”输出，为了全效运行，“Left（左）”和“Right（右）”输出必须采用幻象电源供电：

     ·在“Sum（组合）”模式，来自左输出的幻想供电也将提供右通道的电源，但是驱动器的功率降低。为了使DI200Pro在该模式正确运行，左、右输出应连接并采用幻象电源供电。

     ·在“Split（分离）”模式。通道之间没有串扰电源。因此，当只连接一个输出时，应链接到“Left（左）”输入。当“Left（左）”输出也采用幻象供电时，“Right（右）”输出只提供信号。

Beforeinput buffer stage, providing acoustic source for each input channel frombalanced XLR Jack NEUTRIK Combo A series connector orunbalanced RCA connector.

Asmentioned above, “Left” and “Right” input can compose two channels, “Left”input can separate “Left” and “Right” output. To be high-efficiency operation,“Left” and “Right” output must usd phantom electricity to power up.

In “Sum”mode, “Left”output’s phantom electricity will transfer to “Right” channel’s power supply.

In “Split”mode, there’s no crosstalk source. So when connect one input, you’d connect“Left” input. Meantime, using phantom electricity in “Left” output, “Right”output only provides signal.
