Putting into service r r 1 3 -J 7 48V+4V Power supply and connections The MKH 70 P48 is designed for use with a phantom power supply between 44 and 52 V, as prescribed in DIN 45596. Plug: Wiring: Impedance: Min. terminating impedance: 3-pole XLR balanced 150 Ohm 1000 Ohm Note: Extension cables should, if possible, be inserted between the power supply unit and the audio recorder or mixer. Total cable length should not exceed 200 m. At greater lengths the cable capacitance will affect microphone frequency response at the upper end of the response range. See page 15 for powering and connection possibilities. 11
