Thanks for your post.
Sorry to hear of your troubles getting started. It sounds like some settings may just need to be adjusted here. Make sure to check with our Technical Support Team to see what could be going on here.

Note* The iRig Recorder 3 app has a COG WHEEL in the lower left hand corner. This can be used to change the Channel input. This will have MONO, MONO SUMMED, or STEREO options.
