9.5 How to avoid feedback issues when you play
with mic and piezo.
Audiofeedbackisaspecialkindofpositivefeedbackwhichoccurswhena
soundloopexistsbetweenyourmicandtheAMPorPAspeaker.
Thetwomajorparametersthatdeterminestheamountoffeedbackarethe
distancefromyourcabinetandvolumeofyourmic.
Therearetwomainfrequenciesmostsensitivetofeedback.Therstareais
theLOW-LOWMID(100Hz-250Hz)andthesecondareaistheMIDarea(400Hz-
1.5KHz).FortheLOW-LOWMIDareathenotchlterisaperfectsolution.Forthe
MIDareayoucanusetheLOWPASSSHELVINGFILTERswitchandtheMIDknob.
Bychangingthephaseoftheblendedchannel(PhaseALLswitch)youvirtu-
allymoveyourinstrumentintoanotherphysicallocationandthereforeyou
changethefeedbacksettings.
ByboostingthelowendwiththeparametriqEQaround100HZandreducing
theLEVELofCH2,youcanhaveagreatbottomendwithlowfeedback.This
