Query: Seems great but working correctly

Seems to be defective.Can only rec with the Main Mix stereo output.Individuals channels give me from no sound to AM radio noise.I've sent an email to Alesis last friday. Almost a week without any reply.I can use it with the Main Mix output only, the price is to high in this case.I was looking to buy more stuff from them, but for now, I've changed my mind.
