User manual SENNHEISER MKH 815 T

[. . . ] Either condenser- or dynamic microphones from Sennheiser electronic employ the principle of voltage matching. This "no load condition" has the advantage that neither impedance variations of the microphone output nor of the amplifier input have a noticable Influence on the total performance 01the system (e. [. . . ] Should - however - the input impedance be smaller than 200 Q, a resistor 01appropriate value should be placed in series with the microphone so that it "sees" at least 200 Q. The voltage division caused by this series resistor must, 01 course, be considered. The same method can be used when a higher output impedance 01 the microphone is demanded. In this case again, aseries resistor can be used to provide correct matching. This has the advantage that even with long cables induced interference signals can be disregarded. Also the internal noise produced by the microphone does not contribute to the total noise level. It should be stabilised and tiltered, so that the unweighted noise voltage is less than 1 mV. Swivel Mount MZG 415 The swivel mount gives the possibility to use the desk stand together with the microphone clamp or the shock mount for the MKH 406. Desk Stand MZT 441 The MZT 441 is together with the swivel mount MZG 415 and the microphone clamp MZQ 415 or the shock mont MZS 415 a stable desk stand for the MKH 406 P 48. shock Mount MZS 415 The shock mount can be connected to all tripods , booms , etc. With %" threads and prevents recording being disturbed by footfall for other strong mechanical disturbances. Desk Stand MZT 100 This sturdy and stable desk stand with its highly effective sound insulation is especially weil suited to those recording situations in which knocks and handling noise are unavoidable e. [. . . ] Power Supplies MZN 16 P 48 and MZN 16 P 48-U Power supply unit for 48V phantom powering according to DIN 45596. Connecting Cable KA 1 und KA 7 Tripie conductor shielded cable fitted with 3-pin standard plug according to DIN 41 524 and 3-pin standard socket. [. . . ]
