WL183 and UT: Feedback problems

Date Updated: March 2, 2018 FAQ #511
We bought a UT4 wireless receiver and UT1 transmitter with a headset and a presenter WL183. We have a problem with the WL183, it feedsback at very low gains and we are unable to use it. The WL183 is not mentioned in the brochure. Is there a reason for that? What do you recommend as a solution for the problem?

The WL183 is omnidirectional; the headset microphone is directional. Typically, an omnidirectional microphone is more likely to feedback. Changing to a directional lapel mic, like the WL185, may help, but it is not a guaranteed solution.
