I just purchased the firepod yesterday and I'm having problems with getting any real level. I tried to record separately a vibraphone (with a MXL V67 with phantom power on) and vocals with an Audix OM5 and in both cases, I barely get any level on the channels I decide to record on. And I mean, barely any. I'll be lucky if the meter on the channel even lights up. What am I missing? Is the unit defective? Is there a pad somewhere?
