技術手冊的部分看不懂... - 喇叭音響

請問各位專業的大大們:

我有一個技術手冊，講的是XLR接頭的相關內容，

但真的看不懂，不知道要怎麼翻譯解釋，可以請教一下嗎，謝謝!!

The ANALOG INPUTS are a pair of female XLR-3 connectors marked
LEFT and RIGHT. The inputs are electronically balanced, with an
impedance of 40k ohms. With the INPUT LEVEL controls up full,
a 6.75dBu tone will produce a full scale output, approximately
15dBu with the OUTPUT ATTENUATOR in the –10 position and 25 dBu
in the 0 position. Refer to Table 3 for input and output connections.
