Q: 9. How to reduce feedback

A: Proper placement is crucial. You want to ensure you are close enough to your source --in this case, the mouth of your presenter-- to achieve adequate gain with minimal ambience, yet far enough away as to not to pick up every breath between phrases. Once you've found your sweet spot, implement a few bands of parametric eq to catch the first frequencies that begin to propagate. Parametric eq's are easy to come by on most digital consoles but if you are working with analog gear, inserting a graphic eq at the end of your channel --after compression and before any channel groups or mix busses you may be routing through-- should also allow you to notch out the first few problematic frequencies and achieve adequate gain without carving away too much of the tone and timbre of your presenter's voice.

Q: 10. Do you disconnect headworn mic from transmitter to fit in case?

A: Yes, you will need to disconnect the Sennheiser SpeechLine Digital Wireless SL Headmic 1 Headworn Microphone so it will fit properly inside of the case. The case will also hold the wireless bodypack transmitter, but it may not fit into the allotted space when the microphone is connected.
