The EM-362, neck-worn microphone is designed specially for mosque (Imam) use during prayer. Its unique design suspends the microphone in front of the speaker’s mouth optimizing speech pick up and avoiding being brushed against by the movement of body during prayer creating unnecessary noise. Microphone positioning made easy with the flexible shaft. High sensitivity and wide-range frequency response ensure sound clarity whether user is standing or in praying position. Microphone has the option to operate either with 2 x “AAA” battery or phantom power. There is an ON/OFF switch allowing user to switch on and off the microphone when needed.  Power Source 3 V DC (2 x ''AAA'' batteries) or Phantom Power: 9 V ~ 52 V Microphone Element Electret Condenser Polar Pattern Cardioid Rated Impedance 600 Ω, balanced Rated Sensitivity -35 dB ± 3 dB (1 kHz 0 dB=1 V/Pa) Frequency Response 60 Hz - 20 kHz Cable Length 7 m Connector Output ¼'' balanced L plug, 200 mm Operating Temperature 0 °C - 40 °C Finish Battery Case Unit, Switch Unit, Mic Unit: ABS Resin, Black Flexible Shaft: Copper Alloy, Black, Paint, Shield tube Wire Hanger: Steel wire shield rubber, Black, Paint Dimensions (H x W) 260 x 135 mm  Weight 190 g (exclude battery)   read more
