Webinar: Maximizing Gain-Before-Feedback in Your Sound System | Shure

The webinar covers the topic of maximizing-gain-before feedback. The video answers questions like what is feedback, when does it occur, and how do you improve it?

It's just kind of funny, that after viewing several videos on getting rid of feedback, every one of them starts out with lengthy explanations of what feedback is. I figure if you're watching these, you already know.

Thank you for these series! Very helpful

Having a hard time getting the shure MX412s. To not feedback even with lots of editing. The change occurs when a different speaker comes up seemingly, and the mic isn’t near or inline to any speaker

Love this talk! Very educational and entertaining. Keep it up!

The problem equation at time 13:50 (20Log 15) isn't 24.5, but is 23.5. This system will have a NAG still greater than the PAG, so it will not work.

I understand the importance of distance (mic to mouth, and mic to speaker), as well as EQ. What I'm still wondering about is transmitter settings. On my transmitters, I have the option of boosting and lowering sensitivity. Right now I have mine set to 0dB. I could go +/- 6dB or 10dB. I have the gain knobs (sensitivity) on my mixer for each mic channel set to 9 o'clock as well as the output level of my amp. My amp and speakers are pretty beefy for my venue, but the audience still has a bit of problem hearing, so I want to be able to pump out more volume, but as soon as I do, I get feedback. Even with the omni element right next to the child's mouth, and speakers pointed away, and NO monitors, I have issues if I start getting much louder (of course with unidirectional hand mics, Chris Rock could shout into it with no feedback. It's only the headworn omni's that give me problems). I'm wondering if I would be better off putting the transmitters to -10dB sensitivity, still putting the element as close to the mouth as possible, telling children to PLEASE speak loudly, and increasing the gain on the mixer, if the net result would be ability to pump out more volume from the speakers than I currently do. It would kinda be a trade off of gain (taking it away one place and giving it back another). But I'm thinking if the MIC is less sensitive, the omni "ball" of audible pickup will be smaller and lessen potential feedback, even if the speakers are louder than before (which is what I want).

Hello, what happens when you have a remote call con conference room and you want to use speakers to hear the call and MIC to talk at same time by the same person?
