Does a ribbon mic need a preamp?
A ribbon microphone needs to be paired with a preamplifier that has high enough input impedance that it won't load down the microphone. The lower the input impedance, the more the ribbon becomes damped, meaning that its movement is restricted.
How do you protect a ribbon mic?
When not in use, keep the ribbon mic covered.
When you are not using your mic or if you're transporting it, store it in the AEA foam-lined case, inside the included plastic bag. This will keep dust and fine pieces of “tramp iron” floating through the air from sticking to the strong magnets surrounding the ribbon.
How much gain do ribbon mics need?
How much gain do ribbon microphones need? Ribbon microphones need at least 65dB of gain to work. Unlike standard dynamic microphones, ribbon mics require a more significant amount of gain to operate. This is because they are low-output devices.
