Beyer M320 Dynamic Ribbon Microphone The M320 is from the 60's. These were used in the film industry. It is a Hypercardioid with 30-18,000 response. With 200 ohm impedance. There is some discoloration on the mic body. I am unable to test the microphone. Because I don't have the connector that is needed. The DCR measures less than .5 ohm.
The microphone will be sold as is, since I have no way to test it. The grills are in very good condition.
