ไมค์ RTA Linear Audio KM 6
KM-6 is a new measurement microphone, it could capture a wider frequency response than KM-2. The upper limit could reach 30kHz, specially designed for measuring sound reinforcement and PA systems. It is designed to work with spectrum analyzers for measuring frequency response and sound pressure levels of loudspeaker systems. The KM-6 is the ideal microphone for the measurement of audio signals in research, development, field reverberation testing, and other applications. The narrow tubular construction ensures that the microphone has negligible influence on the sound field so that an increase in sound pressure is avoided with high frequencies. A natural reproduction is achieved due to the linear frequency response.
