Anyone have any comments about the quality of theses mics?
Joe Meek m47 large diophram studio microphones
The JM47 is a very high quality true capacitor microphone with FET impedance converter and transformer output. (NOTE, this is NOT an electret microphone)
The capacitor element is manufactured to the classic ‘centre electrode’ design which provides smooth extended frequency response without low frequency boominess. Quality is further enhanced by using dynamic feedback actually at the capacitor element. This original technique eliminates distortions which can occur when using this type of microphone for high volume levels.
The capacitor membrane is microfine ‘mylar’ with gold sputtering, voltage polarised by phantom power.
The microphone body is made of brass with double screening of the transformer. Connection is via screened balanced audio cable with 3 pin XLR connectors.
Frequency response:substantially flat 20Hz to 20KHz
Recommended load impedance:2Kohm
Signal to noise ratio: 74dB Dynamic range:126dB
