It sends the audio to BOTH output A, and output B, so that you can monitor the sidetone in near zero latency, AND send that same audio over to the voicemeeter vaio virtual sound card which connects to the input of MUMBLE or any other morse code over the internet program input.

INPUT 3, is the mixer's own virtual sound card, voicemeeter vaio, which receives the audio from a software cw keyer like dahdidah. INPUT 2, is using VB-CABLE B, which is only receiving the output of MUMBLE, and by not selecting the B circle on this input mixer, then the audio from this 2nd input only goes to the real soundcard and not the virtual soundcard(which prevents the MUMBLE output from getting back into the MUMBLE input)ģ.

INPUT 1, is vb-cable A, which is receiving audio from any cw keyboard app, and not only is able to send it to the soundcard in near zero latency for monitoring of the cw sidetone, but also sends it to audio output 'B', which is a virtual sound card which connects to the input of any MORSE CODE OVER THE INTERNET PROGRAM like MUMBLE on iCW.Ģ.
