Plug and play, plug directly into your devices with USB port, no needed drivers.With the USB terminal to supply power, the condenser microphone needs no 48V phantom power, battery, or other assistive devices.Cardioid pick-up pattern minimizes background noise and isolates the main sound source.2m long leather cord extends your music space freely and meets your need of all aspects of enjoyment.Wide frequency response (30Hz-20kHz) makes vocal performances sound clear, natural and vibrant. How to setting it?Plug the USB cable to your computer at the same time. Ready for use.If the microphone cannot be used to your device, please check if your device has set itself correctly with the microphone. If not, please follow the step to setting it. Step 1: Open your control panel, and click on /"sound/", a window pops up.Step 2: Select the recording, you will see the microphone is set up or on default.Step 3: Double click the microphone if it is already connected., and then setting yourmicrophone properties. 1.Unplug the USB cable to check whether the pins at the bottom of the mic are loosened.2.Restart computer and re-plug the mic to other USB port.3.If the /"USB PnP Audio Device/" appears in the sound settings of computer(below are the methods how to get to sound settings), the mic is able to work.(Windows: Right click speaker icon on right corner of computer→/"Recording Device/"Mac: Click /"System Preferences/"→/"Sound/"→/"Input/") If the mic disconnects itself without warning, what can I do?Answer: There are two reasons for this situation. One is that the poor connection. The other is that the USB cable is broken. If you have tried to replug the USB cable into the mic, and plug the mic to other USB port, then it will be the problem of the cable. If the mic has hissing what can I do? 1.Re-plug the USB cable into the microphone. If the cable gets loose, noiseis easily generated or transmission of signal may run into problem. 2.Reset computer and re-plug microphone into other USB port. 3.Place it not too close to any power source or computer host. Check whether there's smart-phone near by the USB cable. 4.Set the on-body control of mic and input/output level of computer at 50%-75%. Volume is the culprit for noise. (Windows: Right click speaker icon on right corner of computer→/"Recording Device/"//"Playback Device/"→right click /"USB PnP Device/"/default speaker→/"Properties/"→/"Levels/". If there's /"/"Microphone Boost/"/", turn it to 0-10dB. Mac: /"System Preferences/"→/"Sound/"→/"Input/"//"Output/"→/"Input Volume/"//"Output Volume/") 5.(If using Windows computer,) disable all sound effects. (Right click speaker icon on right corner of computer→/"Playback Device/"→right click the default loudspeaker→/"Enhancements/"→click /"Disable all sound effects/".) Hope these methods could help eliminate noise and make the mic sound better.
