Humming sound when I record


Sounds like it might be feedback from another source or perhaps a loose connection. Try moving the microphone away from power sources or anything that might cause feedback, such as speakers etc.

How do i get rid of feedbacks when i use my E6i Earset, am raning it through an AKG PT2000


Feedback is caused when a microphone's volume is returned out of the speakers, and then picked up again by the microphone causing a loop. The sound is amplified, picked up by the mic ,and then reamplified causing the feedback.
The first step is to make sure you are an adequate distance from the speakers. Also make sure the speakers are not behind you, but in front of you again allowing more distance and keeping the feedback down.
The most logical thing is turn the mic down to a lower level. Countrymans are very sensitive so adjusting the volume in small amounts will work too.
If all else fails, you may need to add an equalizer to your system if you do not have one. This will allow you to adjust out the frequencies that ring the most. The more sliders on an equalizer, the more adjustment you have. If you do have one already ,start from flat (all sliders straight across in the middle) and gradually inch up each slider individually until you hear the feedback ringing in the frequency it did before. You then slide the slider down below the middle to give you more volume before feedback. Don't go crazy here, and adjust only a few sliders down as needed. You will start losing overall volume in your sound system if too many are adjusted down.
Good Luck

What are the hazards a sound engineer can get from


Here is some very general info, however for more detailed info, I need more information on what your using it for. Speechs, Play, Vocals, Bands? Inside or Outside venue?

For Vocals you should have no problems with a Wireless Handheld SM58, they work over a large range, however still have a limit. Make sure the receivers are always close enough to the mics to hold a reliable connection.

Wireless Lapel Mics (Clip-on) are more troublesome, as they are generally consenser mics which are more susceptible to feedback. You also need to place them somewhere in range of the person's mouth, whist avoiding placing somewhere where you will get alot of fabric movement whist moving around, or you will hear that very loudly FOH. You also need to deal with body-packs and wires.

Leturn mics are generally easier to deal with than Lapel, however again are Condenser and more feedback prone.

I would reccomend the SM58 where possible, as it is much easier to work with, and you are more likely to get a better sound with less work.

Hi everyone, i am a vcliast and have been singing


The speakers MUST be in front of and pointing away from the microphone.

I don't know what you mean by "crystalized" as that mic is a dynamic type.

If the speakers are in back of you you WILL get plenty of feedback. If you must run that way, then you need an anti feedback processor. The device shifts the pitch slightly so that feedback can't occur.

Mic is recognized by the computer, but not registering sound. Help?


Hi,

Try this:

click on start, control panel, hardware and sound.

Click on manage sound devices and click the recording tab.

Make sure you have a tick on the mic you want to use and double click on it.

Make sure it says" Enabled" in the device usage box, then click on levels.

There should be 2 sliders, one is the volume of the mic and the other is microphone boost make sure the Microphone volume is near or at 100

It not too good using microphone boost but you may need to use it a little, if you set it too high you will get the horrible feedback screech.

I hope that helps..

Mike

M-audio buddy feedback from mlx 990 condenser mike


Hey I Have These Mics They Work Awesome. But Yes Feedback Is A Problem You Need To Move Away From The Speakers Way Away. Try Lowering Your Highs Or Invest In A Feedback Eliminator They Are Like 89 Bucks But Obviously That Would Almost Cost As Much As The Mic Set. Anyways Feedback Is Made When A Microphone Can Hear Itself Maybe Try Headphone?

That is a great mic. It has a lot to do with the room your in and acoustics of it. If you are too close to your PA or monitor, it will also feedback. Lowering treble and reverb will also help.
