Thanks for the input peeps. I'm using the correct impedance settings for passive pickups and I'm running the unit direct stereo out via XLR outputs direct to a mixing console. This problem is present with any PA I've performed on (Mackie, QSC, JBL, Toa, EAW, EV) as well as any console (Allen and Heath, Midas, Behringer, Presonus, Soundcraft). For live use I have in ear monitors. My JH Audio Roxanne IEM's and my JH 16 Pro IEM's all exemplify this same issue. If I record direct to my Mac via USB, or any other method, the same characteristics are present.
