Neumann USM 69 i mtColour:blackThe USM 69 i stereo microphone has two separate dual-diaphragm capsules. These are mounted vertically and rotate against each other. The directional polar patterns can be selected separately for each capsule. The capsules operate independently from each other.Features:Switchable stereo microphonesTwo pressure-gradient transducers with double membrane capsulesMS- or XY-stereophonyCapsules rotary by 270°Very low noiseAperture and pick-up angles freely choosableDirectional characteristics reproducably switchable, omni, wide angle cardioid, cardioid, hypercardioidTechnical Specifications:Acoustical operating principle Pressure gradient transducerDirect ional pattern Omnidirectional, wide-angle cardioid, cardioid, hypercardioid, figure-8Frequency range 20 Hz … 20 kHzSensitivity at 1 kHz into 1 kohm 13 mV/PaRated impedance 150 ohmsRated load impedance 1 kohmsEquivalent noise level, CCIR1) 24 dBEquivalent noise level, A-weighted1) 13 dB-ASignal-to-noise ratio, CCIR1) (rel. 94 dB SPL) 70 dBSignal-to-noise ratio, A-weighted1) (rel. 94 dB SPL) 81 dBMaximum SPL for THD 0.5%2) 132 dBMaximum output voltage 3 dBuDynamic range of the microphone amplifier (A-weighted) 119 dBSupply voltage (P48, IEC 61938) 48 V ± 4 VCurrent consumption (P48, IEC 61938) 2 x 0.7 mAMatching connector XLR5FWeight 510 gDiameter 30 + 48 mmLength 293 mm
