Title: beyerdynamic M 840 N review / large diaphragm condenser microphone
Author: Nick Mavridis
Translated from the original German article
"(...) Today, the double-diaphragm condenser microphone MC 840 is our test object (...). Meanwhile, both gold-coated large diaphragm capsules can be omnidirectional, turn eight, wide cardioid and hypercardioid. Surely only the anterior capsule will be used frequently, which in this design principle results in the known "normal" cardioid polar pattern.
The Beyerdynamic is operated with phantom power. It is pleasant that also 12 volts are completely sufficient for the device, the permitted maximum is 52.
In this test I did not expect a colourful sound fireworks or other spraying of individuality anyway. So I approached as part of our series of tests the MC fairly neutral, as expected the Beyerdynamic carried out its duty without emotion." It does not care " I commented on the microphone through the window of the control room. My colleague called the microphone even the "social worker among the large-diaphragm microphones". But one does the 840 wrong when one makes fun of it: it is working dutifully and exceptionally conscientious .
It does its job with a reliably high quality remaining unobtrusive and never pushing itself in the foreground. What perhaps may still sound a bit negative, is meant different: Disturbing noises or even errors in the signal are nowhere. The highs are finely resolved, but never harsh. In the bass range the microphone is rather "cool" and dry, it is never unclean, spongy or "boomy". Excellent! As expected the different polar patterns work in conjunction to their frequency response (and of course its directivity) - the "textbook" sends its regards.
Conclusion: The Beyerdynamic MC 840 N is a multifunctional, good-natured, but surely something characterless tool. As an all-rounder in my opinion it constitutes an excellent basis in studios where more than just voices are recorded or where microphones with colorations are not needed or are additionally available. For a newcomer, I would recommend the microphone only conditionally, because it requires the skills of engineers and other equipment to form from the signal what is ultimately needed. With the MC 840 the German manufacturer has a typical German piece of engineering on the market: Technically excellent, at the same time modest and useful. You will still hear and can’t get enough of this microphone in 40 years. The chances are very good that it will still work as on the first day!
Regarding the sound a very neutral and discreet microphone
Suitable for a number of applications
Very good workmanship
Rather unsuitable for newcomers
