of the singing or speaking voice. Very low frequencies are filtered out to reduce pickup of mechanically induced noise, room rumble, etc. The goosenecks adjust silently. Supplied with the microphones is the WS 9, a highly effective foam pop filter. Its two stage design greatly reduces explosive breath sounds. A low cut switch built into the electronics housing further reduces breath pops and handling noise. Optional accessories include the LM SM lockable shock mount, which provides mechanical isolation when mounted in a pulpit, lectern, or table top. The microphone connector is a male 3 pin XLR type for easy plug in installation. The output is balanced and low impedance which allows long cable runs without hum pickup or high frequency loss. Superior RFI protection is also provided. Requires 12 48 V phantom power. Specifications Type Unidirectional condenser. Element Electret condenser. Frequency response typical 80 Hz to 15,000 Hz 110 Hz to 15,000 Hz with low cut. See Fig. 1. Polar pattern Supercardioid. See Fig. 2. Impedance 150 ohms, balanced. Recommended minimum load impedance 1000 ohms. Open circuit sensitivity 6 mVPa 44.5 dBVPa. Power sensitivity 42 dBmPa. Equivalent noise level 28 dB SPL typical 0dB.0002 dynecm2, A weighted. SN rati 66 dB at 94 dB SPL. Maximum SPL 120 dB SPL produces 3 THD. Polarity Positive pressure on the diaphragm produces a positive voltage on pin 2 with respect to pin 3 of the output connector. Operating voltage 12
