It is a rugged, low-impedance dynamic mic that can be mounted vertically for non-directional pickup or horizontally for directional pickup. It was popular with radio stations like CBS for many years. They are difficult to find complete and in good condition, so this a pretty rare mic. I have not tried this out as I don't have an adapter for it to plug into an PA system. Well good luck. Without the "ring" shown in the brochure photograph, the microphone is omnidirectional, whether vertical or horizontal. Place a Bid!
