Ext. mic muted lights stills on

Check the device manager for duplicate devices and make sure that the on board devices are disabled

I for 1 don't know. But try to go to www.Turtle Beach.com they can help you out. I have Turtle Beach Ear Force XC1 and my mic I can talk but I can't hear anything but if your mic isn't working properly try using a different controller. If that doesn't help try getting a brand new mic.

Either mic "mute" is on or mic capsule is dead...dropping these low-end wireless mic's are usually fatal. Upgrade and you won't regret it.

If the mic mute switch is not on and there is no red light in the mic arm then its likely you have a check in the 'mute mic' box in your sound manager. Open Volume control, choose options->properties-> recording. Check for checks in the boxes and remove them. Also make sure the slider for the mic is about half way up.

Hi,

Just check the button on the mic or the properties of the mic... from there only you can select the option to not mute.

the grey means its not finding the mic. plug the mic into another plug for the mic. if it still is not working then your mic card slot might not be working.

Make sure the microphone and the receiver are still broadcasting/receiving on the same channel.
Check that all of the appropriate connections are right from the receiver to the mixing board are connected as well.
I hope this helps!
God Bless you!

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.
