1.  Signal Level & Clip Indicators% l& \3 P" `4 A5 x* N. q7 i. ?
The LED signal level indicators show that you are inputting a proper signal level. With a proper input level, the green signal LED should be flickering, but the red clip indicator should NOT ever be lit. The clip indicators light and show that the input level has exceeded 0dBFS. $ V( ^) ?! R2 A! P. m: j/ _

In this mode the left and right channels are passed through to their respective outputs at the level set by the Direct Monitor Level control. Press the button again to switch to Mono Direct Monitoring, which sums the left and right direct monitor channels to mono. Mono mode is useful when the two inputs are being used for separate instruments, or when only one input is being used.

不是做测试，纯粹用来接本本听歌的，测试我有专用声卡SB0270了:loveliness:

:lol: 接本本听歌还是用DAC1USB吧
作者: kingcole    时间: 2008-2-20 16:00
作为声卡，DAC1USB我觉得不是个好选择，至少在驱动方面没有声卡大厂的做得好，做DAC倒是没得说的，总感觉DAC 1 USB上的USB接口仅是一个附加的接口而已，决绝不是戏玉
