This session we will Look into the RCA seventy seven series of ribbon mics starting Using the quite first design, the 77A.
the very first two mics in the series, the 77A and 77B, had a fixed unidirectional pattern.

Instead of staying open on both sides as in the conventional velocity microphone, the ribbon element In this particular microphone is coupled to an acoustic labyrinth which forms your body percentage of the microtelephone.
