Hi Richard, If I understand this correctly, you have the pc mic, Spkr Out of pc#2 and Mic In of pc#1 all in parallel. The output impedance of the Spkr Out appears to the pc mic as a very low impedance connected between the Mic In and ground. This forms a voltage divider which will drastically reduce the mic signal at Mic In. Also, depending on the type of microphone, you run the risk of dumping the output power of Spkr Out into the microphone and destroying it. If you can feed Spkr Out of pc#2 into Line In of pc#1 and the pc mic into Mic In of pc#1 everything should work fine (provided that your mic still works). Also, using the sound card mixer controls, you now have independent control of the mic and spkr levels. Hope this helps. 73 de Jim Smith VE7FO Richard Thorne wrote: Blank
