[Central-Electronics] Help - D-104 mic for CE200V

[Fern]

Hi Dave:  I would check to make sure that your D-104 has audio output. 
Either use a very sensitive ac meter or an oscilloscope for that. Also the 
D-104 is a very high impedance mic. I think that the Shure 444 is a much 
better choice for good audio from your 200V.  Fern   VE7GZ
