Lustraphone VP64


The particular mic is 50KΩ. Measuring with a ohmmeter is a guarantor to blow the ribbon. The measurement was done with an Escort LCR meter which sends a tone for the measurement to take place. It measures impedance at ac.


The mic came with a very very long cable. More than 25ft. It sounded interesting but not at its best.


The cable was cut and only a few feet left. Immediatly treble shined.


There still was a mid bass heaviness at close distance. A Pleiades 1H or 6.1H was connected in parallel with the 50KΩ output. It shined and the difference in cable capacitance creates an air similar to that heard on The Power of Love - Frankie Goes to Hollywood. Still the mic is a bit colored at mid range but the sound is very good.


Possibly a Pleiades (R,L) filter specifically made for high mic impedance with sound better.
