The following instructions provide a way to test Audio output from a TalkShow. In this setup incoming call audio will be routed out via the XLR Output, which is routed back in via XLR Input. Simply talk into the mic from whatever device you're using to make the call and after you talk you'll hear what you just said from the same device, thus confirming your audio is looping and both XLR inputs/outputs are working as expected.
1) Under Channel settings, click on the Return to Caller tab and make sure Audio Source is Local (Input 1) and Audio Types is Line.
2) Connect an XLR cable from Output 1a to Input 1a.
3) Make a Skype call into the TalkShow with an external device (like a phone or another computer), making sure it has a mic and speaker.
