Computer RF Getting Into Microphone
Since purchasing a tabletop usb condenser mic, listeners on a chat site tell
me they are hearing severe intermittent "squealing & distortion". I am using headphones, no speakers connected to the computer so i can rule out audio feedback as the problem. I'm of the opinion that rf from the computer may be getting into my mic. The mic's usb plug does 'not' have a ferrite rf choke. Besides placing a choke on the above usb plug, i will also place a choke at the base of the mic. I will try to acquire ferrite chokes from a discarded vga monitor or purchase "snap-on" chokes from radio shack. Any suggestions, advice etc. would be appreciated. Thank You. |
