Hey guys got an obscure question I can’t find any information on. I may be overthinking this, but maybe someone will be able to offer some guidance.
I have a line out audio signal that I am trying to pass through the mic port of a CP200D. I was doing this with an older CP200 without issue.
After replacing the 200 with a 200D the audio isn’t coming out right, it’s barely audible and very garbled. I’m wondering just for reference what the typical voltage level of the audio going into the radio from a mic is. I have a Icom that I want to do the same thing on but I don’t have a way to check the mic voltage levels and compare to the line out voltage level. I’ve read that some mics are very low voltage (10mv) and that line out is up to 1.5v and I may need an attenuator.
For some reason I’m not seeing any of this published on tech sheets.
