Description
The WBH54 (wireless version of the Beta 54) is a subminiature, electret condenser head worn microphone. It provides uncompromised sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring. Despite their small size, the condenser element delivers full, clear, and natural reproduction of speech and vocals. The microphone features a durable, low-profile wire frame headband which is fully adjustable for stability and comfort. A plastic carrying case protects the microphone.
* Supercardioid polar pattern provides maximum gain-before-feedback and ambient rejection * Extended frequency response tailored for vocal performances * Able to handle extremely high sound pressure levels (SPL) * Snap-fit foam windscreens stay in place during intensive movement * Available with an in-line preamp or with a TA4F connector for wireless applications * WBH54: Choice of black or tan finish to suit your performance environment
Type : Condenser (electret bias) Frequency Response : 50Hz to 20KHz Polar Pattern : Supercardioid Output Noise (equivalent dBSPL, A-weighted) : 39.0 dB typical; 42.0 dB maximum Signal-to-Noise Ratio : 55.0 dB at 94 dBSPL Recommended Minimum Input Impedance : 20 kilohms Output Level, open circuit, ref. : 1v/Pa at 1 kHz -56.0 +/- 3.0dB 1.58mV Maximum Sound Pressure Level : 144 dBSPL at 1% THD/20 kilohm load Dynamic Range : 105 dB (max. SPL with 20k load, minus typical A-wt. noise) Current Drain : 60-130 microA (microphone only) Output Polarity : Positive pressure on the diaphragm produces a positive voltage at pin 3 (black lead) relative to pin 1 (shield lead) at the output connector of the microphone Power Requirements : +5 Vdc on pin 2, return on pin 1 (ground) Net Weight : 35.35 g (1.25 oz.) microphone only Cable : 1.5 m (5 ft.), small-diameter, shielded, with mini 4-pin connector (TA4F)
