Ribbon microphones

Ribbon microphone is a result of a simple physical phenomenon. When metal particles move in a magnetic field generates an electrical potential between them. In this case the movement is imposed by the pressure changes of the sound waves on a very thin film, from 0.6 to 2.5 microns of high purity aluminum. These microphones have existed for many years. We all remember as used in old radio and with the beginning of the TV era. At that time two microphones captured a Big Band in a studio and the result was amazing. Today, the technology has improved with the discovery of neodymium magnets, which have reduced the magnetic space group and therefore more competitive designs changed compared to condenser mics .

When you have your fingers between the ribbon and hang in the air, you notice that there is no lighter metal, anything that offers less resistance to a sound pressure wave. Compared to the dynamic microphone capsule or condenser microphone, the ribbon "is the air itself", and the condenser a space between two rigid walls. With a snap, we can observe how the belt moves .

Today there are several types of ribbon microphones. Can be divided into two groups: Active and passive. Actives have internal electronics that increases your profit and better impedance coupled between the microphone and preamplifier. The passives microphones are less sensitive liabilities, usually between 1 and 3 mV / pascal , and are more influenced by the input impedance of the mixer or preamp. But both have that naturally characterizes the sound of the ribbon.
