Body: <p>I'm using a -25Db attenuator cable (<a href="http://www.bhphotovideo.com/c/product/767986-REG/Whirlwind_WHH4NL3_5_WHH4NL3_5_Line_to_Microphone.html" rel="nofollow">this one</a>) to connect an audio mixer to my camera. Now, I've tested the cable by connecting my DAP to the camera, and it works just fine. But when I connect the attenuator cable, even without an audio mixer plugged-in, I hear background noise. When I turn on the audio mixer but don't have any input sources for it, the noise is even louder. When I connect a radiomic to the mixer, the loud noise is still there, coupled with the audio from the microphone.</p>
  
  <p>Can someone help me figure out what's going on here? Am I somehow using an attenuator cable incorrectly? I doubt it's faulty considering that connecting a DAP to my camera results in a good, clean signal and no noise on the line.</p>

  I'm using a -25Db attenuator cable ([this one](http://www.bhphotovideo.com/c/product/767986-REG/Whirlwind_WHH4NL3_5_WHH4NL3_5_Line_to_Microphone.html)) to connect an audio mixer to my camera. Now, I've tested the cable by connecting my DAP to the camera, and it works just fine. But when I connect the attenuator cable, even without an audio mixer plugged-in, I hear background noise. When I turn on the audio mixer but don't have any input sources for it, the noise is even louder. When I connect a radiomic to the mixer, the loud noise is still there, coupled with the audio from the microphone.
  
  Can someone help me figure out what's going on here? Am I somehow using an attenuator cable incorrectly? I doubt it's faulty considering that connecting a DAP to my camera results in a good, clean signal and no noise on the line.
