RCF MD 2702 directional moving coil microphone


There is something nice and easy about the sound of this mic.


It sounds quite loud and there are no s sibilant problems.


The reasonant frequency seems to be higher than other mics and this correctly compensates for the proximity effect for a distance of a few inch.


For very close distance the sound was bassy. A Pleiades filter of 100Hz did not sound quite right (perhaps thin) so one may need to use a Pleiades filter is series with resistance or variable resistor as on MD421?. Is this how the proximity effect is compensated on the MD421? Or a Pleiades filter using a wire that has resistance.


The foam may be disintegrated. The mic can be opened by carefully removing the sticker around. Then 4 metal pins have to be pushed in, in a similar way to MD21 or Beyer M 55.


It can then be opened, the foam removed and the grill washed.


Signal path, setup:


RCF MD 2702 - Canford input transformer (400mH primary inductance) - Pleiades V4 preamplifier, 3.4V battery - Realistic Disco Mixer - HD580
