1. Ribbon consist of an extremely thin aluminium foil placed between two neodymium magnets which vibrates with sound waves, The movement of the ribbon in the magnetic field generates a small electromotive force (emf) which can be detected using two wires connected to the ribbon.
2.This signal is so weak so we use a transformer to step-up the voltage.
3.The output of the transformer is now ready to send through XLR cables to preamps.
