GSP 600 Noise Cancellation
Our noise-cancellation microphone works in a way that it is extremely good in isolating outside noise when the position is right.
Here, this is because the proximity effect of the GSP 600 is very good at close distance to the sound source. Consequently, please try to position the microphone closer to your mouth because this way the microphone will be able to distinguish between your voice and “outside” noise!
Otherwise please also check in your Recording Device settings in Microphone properties:
In the Levels Tab
1.) Microphone Level
2.) Microphone Boost (lower it, if it is e.g. set to +20dB)
