The MD 300 is a high-quality dynamic microphone with a frequency response of the transmission factor that has been optimized for intelligibility. It is featured with an especially accurate resolution at high frequencies and a well-balanced low-frequency transmission. It is insensitive to movements of the recorded sound source thanks to the cardioid polar pattern. The MD300 is useful as close-talking microphone for announcers of broadcasting services as well as for high-quality recordings of vocalists and instrumental soloists during live performances.
The frequency response has been optimized for low recording distances with an accentuation of approximately 2 dB between 2 kHz and 8 kHz to raise the speech and high-frequency presence. The change of the low end frequency response caused by the proximity effect is well-balanced without a very strong overemphasis at small microphone distances.
