注意事項(xiàng)  Notice 
 
在只連接一個通道時，雖然DI200Pro將作為單聲道設(shè)備工作，但是，兩個通道都必須通電。以使用立體聲、分離或組合模式。
 
Whenonly connecting one channel, DI200Pro will be single sound channel, but twochannels must be powered up.  Using  “Stereo” and “Split” or “Sum” mode.
 

正確操作  Proper Operation
 
在輸入緩沖級之前 ，從平衡式XLR ,Jack Neutrik Combo A系列連接器或非平衡式RCA連接器提供每個輸入通道的聲源。
 
     如上所述，“Left（左）”和“Right（右）”輸入可以組合到兩個輸出，“Left（左）”輸入可以分離為“Left（左）”和“Right（右）”輸出，為了全效運(yùn)行，“Left（左）”和“Right（右）”輸出必須采用幻象電源供電：
 
     ·在“Sum（組合）”模式，來自左輸出的幻想供電也將提供右通道的電源，但是驅(qū)動器的功率降低。為了使DI200Pro在該模式正確運(yùn)行，左、右輸出應(yīng)連接并采用幻象電源供電。
 
     ·在“Split（分離）”模式。通道之間沒有串?dāng)_電源。因此，當(dāng)只連接一個輸出時，應(yīng)鏈接到“Left（左）”輸入。當(dāng)“Left（左）”輸出也采用幻象供電時，“Right（右）”輸出只提供信號。
 
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.
