I'm using a MXL990 Condenser mic powered by a Behringer UB802 Phantom powered mixer into my Fostex Mr8. The levels aren't reaching but to about -5 but when a listened there is still some clipping/distortion on the vocals. I'm using a homemade pop filter. Could the pop filter or sensitivity levels on the mic be causing this? The mics on 5 days old.also, is it pretty necessary to have a compressor and limiter when doing vocals? All I have is a mxr dynacomp stompbox.
