SM 7 B : My preciousss

6 years ago

Couple things when looked up close: The 'mid-boost' isn't a boost but a cut; with the switch placed on 'flat' it takes out a couple of db's that could just as easily be equalised after recording, leave it on 'boost' I dare say.

This mike needs some serious encouragement, about 60 dB's. Most microphone amps are great until 40 dB of amplification, above that their quality drops significant, invest in an head amp.

And since this is a dynamic, transformerless moving coil microphone the cable attached to it becomes a part of the signal chain that defines the characteristics of the sound, just like a guitar. The cartridge gives the best response with a short cable; 500 pF terminated with 5 Kohm gives a ruler flat response, assumed that the advertised 150 Ohm impedance is measured at 1 Khz implying the cartridge has an inductance of 24 mH.

All in all the mother of dynamic microphones that sounds great without low- or mid cut, excellent protected against vowel noise and placed shock-proof in a serious sturdy housing. What more to wish? Maybe a build in head amp?

Pros: this is _the_ pro.

Cons: I need more.
