Series MG-45.2Electret Microphonewith Luminous Ring and GooseneckThe microphone MG-45.2 is intended for PA systems,control desks, for table- and wallmounting as well asmounting into cars.Due to the excellent directional characteristic, ambientnoise is effectively eliminated. The danger of an acousticfeedback is minimised.The state of readyness is displayed by a luminous ring.The microphone will be delivered completely withgooseneck. Two different lengths of goosenecks areavailable for adjustment to the particular application.• LED-luminous ring for display state of readyness• For use in highly noise disturbed surroundings• For use at mean speach distance (approx. 30 - 50 cm)• Electret microphone with excellent directional effect• High operating safety by means of integratedovervoltage protector• Gooseneck available in two different lengthsTechnical specification ________________________________________________________Housing..............................................................zinc diecastingColour ................................................................anthracite or light greyDimensions ........................................................microphone: diameter 17 mm, length 34.5 mmWeight ...............................................................approx. 100 g with gooseneck ∅ 9 x 226 mmTerminals ...........................................................4-core PUR-cable, screened, ends tinnedDegree of protection ........................................IP 40 acc. to DIN EN 60529Temperature range operation: .....................-20 C up to +60 C Nb acc. to DIN EN 60068-2-14storage: .........................-20 C up to +60 C Nb acc. to DIN EN 60068-2-14Acceptable relative humidity ...........................≤ 93 % Db acc. to DIN EN 60068-2-30Luminous Ring ________________________________________________________________Colour ................................................................redOperating voltage.............................................12 up to 30 VCurrent drain.....................................................approx. 20 mAElectroacoustic specification___________________________________________________Electroacoustic principle ...................................electretNominal output impedance .............................2 kΩ up to 6 kΩOperating voltage.............................................1.5 V up to 6 VCurrent drain.....................................................approx. 0.5 mADirectional characteristic ..................................super cardioidOptimal speach distance...................................30 up to 50 cmSensitivity...........................................................20 mV/Paf = 1 kHz± 3 dB, U B = 6 V, R L = 2.2 kΩ, f = 1 kHzHolmberg GmbH & Co.
