LAVALIER CONDENSERMICROPHONE MKH124,MKH125T, MKH 126 P48 Introduction The microphone part MK 12 is a Lavalier condenser microphone in RF- technique leaturing a diaphragm 01only 6 mm diameter. Corresponding to its use the microphone was designed as pressure transducer (omni- directional). Therelore, the MK 12 is very insensitive to handling noises. The complete microphone consists 01two parts, the miniature micro- phone and the electronic unit. MH 124, MH 125 T, MH 126 P 48 or the studio transmit
