Pulpit Mic Feedback Solution

I'm looking for an experienced audio engineer who can help me set up my QSC touchmix-30 pro mixer for optimizing a pulpit microphone and reducing feedback. This setup involves only a single channel. Your expertise in handling pulpit condenser microphones, understanding of audio dynamics, proficiency with this specific mixer brand, and direct experience in feedback resolution is important. Your role will be to guide me in setting up the mixer for best audio output via video conferencing. Let's tune it just right.
