mixsit Posted July 14, 2001 Share Posted July 14, 2001 I was looking at the specs on this Audio Technica remote phantom power unit, and it had a noise level of -71dbv. Is there something diferent about the way a remote unit would be designed vs a mixer's power? I've never seen phantom noise mentioned befor. http://www.audio-technica.com/guide/other/access/phantom.html#CP8506 Part time -long time. Link to comment Share on other sites More sharing options...

A noise figure of -71 seems reasonable to me, especially since the microphone preamp will reject that noise due to its balanced nature. Since the DC power is applied to both the plus and minus microphone outputs, it will be mostly cancelled at the input to the preamp. Which results in a lot less than -71 dB of actual noise. --Ethan The acoustic treatment experts Ethan's Audio Expert Book Link to comment Share on other sites More sharing options...
