I'm filming this Sunday with a shotgun mic and wanted to know if anyone could give me advice on setting it up. I saw some responses saying that I should have both channels going through the shotgun mic with one level set slightly lower than the other. Would you recommend using the onboard mic as the secondary mic (setting one channel for the onboard and the other for the shotgun)? Or is it best to only use the shotgun? Any advice/help would be greatly appreciated (any links as well). Thanks
