Labtec engineers designed the AM-242 desk boom microphone with NCAT (Noise Cancelling and Amplification Technology) to provide optimal voice input for Internet communications, multimedia, and interactive audio applications. This proprietary technology provides clear signal input through its unique ability to filter out background noise. By designing the microphone specifically for frequencies associated with speech, and engineering the rejection of background noise, Labtec microphones and headsets using NCAT are the ideal computer audio peripherals for applications requiring audio input. NCAT products are designed to be compatible with virtually all sound cards.
