The Alctron PF8 is a microphone accessory perfect for studio recording, reducing ambient noise and featuring a windscreen. - Type: Microphone Accessory - Brand: Alctron - Model Name: PF8 - Function: Reduces ambient noise - Features: Windscreen - Application: For studio recording Thank you for viewing. I used this when using a condenser microphone, but I am selling it because I no longer use condenser microphones due to my environment. I have lost the filter that fits in the front, so I would appreciate it if you could use a pop guard or something similar as a substitute.
