Hf-Mic Hires
Here’s how to make a RF-Condenser microphone circuit that’s similar to a Sennheiser MKH series mic, Uwe writes – “This RF-circuit is operating at 7.68 MHz and 48 V phantom power supplied. It is tested with a large diaphragm cardioid capsule from Ralf Falk, who himself is designing a LF tube microphone and with a small diaphragm capsule from a Sennheiser MKH415… Lots of experiments, gathered experiences and improvements during the development – with quite satisfactory results, to my point of view.”Link.
