Want it for feedback on a mic there is a masive delay between talking and the sound coming out of the speakers iv tried the mic without it and no delay also if you leave the mic open you get an echo

use a quality condenser cardiod or super cardiod microphone not cheap dynamic mic esp omidirectional. speaker in font of mic. keep gain on mic to a minimum. do not use mic speaker assembly that the mic and cable are one piece. try to point speaker at hard surfaces as these reflect the sound back

Feedback happens when the sound coming out of the speakers travels back into the microphone and then is re amplified and sent back through the speakers

could be the junky 17 inch antenna or could be feedback coming through your speaker.Could also be a problem with your mic.

Squealing sounds come from feedback. Many times is is from an adio source and speaker. Check your radio's switches and jacks to make sure that any external speaker set up in the passenger compartment of the car is connected to the "EXTERNAL SPEAKER" or "EXT SP" jack, and not into one labeled "PA". PA is for "Public Address". When the selector switch is set to "PA" instead of "CB" and the mic's Push To Talk (PTT) button is pressed, what ever sounds picked up by the mic are sent directly to the PA speaker, NOT transmitted on the CB channel. The sound is a high pitched squealing noise that is reduced or eliminated when the mic "gain" is reduced; speaker volume reduced; headphones are used or the distance between mic and speaker is increased.

The feedback can also be from "RF", or radio frequency energy. RF energy feedback is different from audio feedback in that the way to eliminate it is to properly tune or "match" the antenna to the frequency of the RF energy from the radio (in this case, about 4 watts on the low 27Mhz range). This is done by inserting an SWR meter between the transmitter's antenna connector and the antenna. Following the directions included with the meter and adjusting the physical length of the antenna's whip up or down in 1/8" increments will allow you to quickly find the lowest match possible over the range of CB frequencies.

Failure to obtain an acceptable match ratio can result in damage to the transmitter and RF burns to the operator. A match of 2:1 (two to one) is acceptable, but the lower you can get the better. Anything in the 1.5:1 (one point five to one) down to 1.1:1 (one point one to one) range is excellent - with 1.1:1 being ideal.

I hope this helps & good luck!

your microfone is position wrong try lower the input mic or re positioning the microphone elsewhere where they dont hear the speakers. block it put something around the mic, so the sound dont bouce back
youre getting sound feedback.

You're not supposed to have the TV sound and the Bose osund on at the same time. Due to differences in digital audio processing there will be delays that sound like echo, not feedback.

If you truly have feedback, define the audio connections and exact cabling to/from all components..

Feedback is caused by a loop between the microphone and speakers. You can try to turn your volume down. If not then tell the other person to move their mic away from their speakers

Its important to set your webcam mic as default (the one you want to use) especially if you have a laptop with a built in mic as well

TEST SPEAKERS
Right click on speaker icon in System Tray or from Control Panel
Select "Playback Devices"
The speaker icon ( checked as working) and volume level graph should be visible
Right click on the volume graph and click "Test"
Left hand speakers followed by right hand should be heard

SET DEFAULT & TEST MIC
Click "Recording" tab.
To set required (webcam) mic as default - click on mic font to highlight and click "Properties"
In lower dropbox display "Use this device enable" click 'OK'
Click "Levels" tab and ramp up sliders (adjust to suit later)
Return to "Recording". Test mic by speaking and make sure volume graph displays

Restart computer

It sounds as though you are pointing the peavey at the band in a practice situation? If so make sure that each speaker is at about 60 degree angle to either side of the back of the mike (you facing the speakers), most mics reject feedback when the the user is directly in front of a monitor, but Beta 58s' tend to feedback more in that situation. Alternatively (if it is a practice room situation), why not place the speakers behind the band at 60 degrees each and turn to face the band.

Your mic still picks up sound when it's unplugged ?
As far as the other prob goes that sounds like howl round ( feedback ), mute the mic when not talking through it or get a mic with a cardioid polar response pattern ( just ask for a cardioid mic, can get a hypercardioid or supercardioid too but a cardioid would be best for your application, point the mic right at your speaking position with the back of the mic pointing at the speakers wich ideally should be behind the mic, this will help cancel out their sound, puting a limiter on the mic and setting it where it only starts picking up sound when you talk directly into it will help too, but the sure fire way to solve the prob is to mute the mic when not speaking into it. What you definitely don't want is an omnidirectional mic, for what you are using a mic for.
