Why do we have a feedback problem with our lapel mics?
There can be a few answers although typically it is the lapel channel EQ which will be misused. Many times LO’s will be boosted (sometimes considerably) to ‘fatten’ the voice. Other times HI’s will be boosted to give the voice a ‘hi-fi’ type sound. These are bad practices and feedback is made worse due to the changing positions of the wearer. As a rule EQ boosting should be kept to an absolute minimum. This is true of any vocal mic. Often times the sound quality of the mic can be improved by repositioning it on the wearer. Other times the mic quality itself can be a limiting factor. Generally, you’ll want to engage the HPF (high pass filter) or Lo Cut on the channel strip of the Lapel mic. You also may further need to cut the LO’s to de-emphasize sensitivity to feedback in the low frequency range and to remove any rumbles. If the mic still has a feedback problem you should use the sweepable EQ to notch the offending frequency. You can also use the midrange sweep to take out ‘honkiness’
