关于KPA的MAIN OUT进声卡录音的问题

arranger

想请问一下各位，如果KPA直接接声卡录音，应该用MAIN OUT的TS口（6.5）还是XLS口（卡农）呢？
我是一直用TS口接声卡的LINE IN，今天翻看说明书突然看到这一段（如图），大概意思是XLS口接声卡用48V供电，英文不好可能理解错误，我用TS和XLS同步录了一下，反向抵消不了，但是听起来一模一样，该有的噪音也都在，声卡是RME的UC，请各位大神帮忙答疑解惑，非常感谢！

说明书原文如下：
This is your stereo MAIN OUT. Use these outputs to connect to a mixing desk in a recording studio, or to the front-of-house mixer in a live situation. These outputs deliver the entire Rig: Amp, Cabinet, and all E ects. You have a choice of XLR (balanced) or quarter-inch TS-jacks (unbalanced). The XLR outputs are protected against 48V phantom power fed by a mixing desk. However, you should avoid feeding phantom power into the Pro ler if you want the best audio quality. Like all inputs and outputs, it o ers a GROUND LIFT to prevent a hum loop.

"you should avoid feeding phantom power into the Profiler"说的是XLS口接声卡时  不要  用48V供电！

录音最好直接用它的数字输出口直接进声卡的数字输入口，否则多了一次数模转换和一次模数转换。
