The TELEFUNKEN Elektroakustik recreation of the iconic U47 is exact in every detail, down to the historically accurate BV8 transformer and M7 capsule.



For more than 70 years the U47 has been a staple of every professional, top tier recording studio.

The TELEFUNKEN Elektroakustik recreation of the U47 large diaphragm tube microphone is true to the original design, even down to the historically accurate BV8 output transformer and M7 capsule, which provides the same rich and vibrant tone that has made the original U47 into a legend.

“I always champion a strong and comfortable performance over sonic perfection, but I remember giving a sigh of relief when I heard Rick got his hands on a Telefunken U47 to track his vocals with. It just means that there would be less work I have to do to make the vocals sound like a ‘record’ and more time getting to add some creative sauces. Without hating on other mic companies, I can just tell you that every voice or instrument pairs uniquely for better or worse with different microphones. I have had great experience with the U47.” 

Kenny Cash – Factory Underground Studio, Connecticut

So, we used the U47 and it sounded great as soon as she put on the headphones and started singing into it. In a sense, this mic makes people sing better. And when it comes time for editing and doing rough mixes and whatnot, it just sits there really easily; you don’t have to do too much to it.
