The Shure Beta 54 is a low-profile, head-worn microphone featuring an electret condenser microphone with a super-cardioid polar pattern. With a frequency response of 20Hz to 50kHz, the unobtrusive microphone delivers transparent, full signal reproduction with minimal noise at the low frequency range. The super-cardioid polar pattern is highly effective at minimizing noise and ambiance at the off-axis sections of the microphone.
The end result is exceptional rejection of signal from monitors and instruments, creating high gain-before-feedback response. The Beta 54 is able to reproduce audio sound pressure levels of up to 149dB without noise caused by distortion and overload. The lightweight headband is size adjustable and designed to wrap behind the head for a comfortable fit during long use. The headset excels in performances due to it's excellent off-axis rejection, however instructional applications, aerobics instruction and boardroom settings are all environments the Beta 54 is suitable for.
