DESCRIPTION AND APPLICATIONS

l'he BEVERDYNAMlC M 55 omnidirectional movmg c0il microphone combines elegant styling With BEYERDYNAMIC"
nany year's experience in the construction of professmnal studio microphones. The M 55 has a good frequency responSi
hat is deSigned to match the requwements of most home tape or cassette recorders. It has an attractively designed solii
netal case. with a specnal transducer mounting to reduce handling nmse when used in ..reporter type" situations.

tls espectally suited as a replacement for the low cost. inferior quality microphone that is commonly supplied With thi
iome type tape recorder.

The movmg coil microphone is by far the most popular type in both professwnal recording and broadcast studios through
out the world. The M 55 is an excellent example of this type of transducer.

rhe M 55 is supplied complete With table stand. microphone clamp and a captive cable,
