Style: CardioidWhat is the 55SH Series II best suited to? The 55SH Series II is suited specifically to vocal applications. Therefore, typically live performance, public address as well as for broadcasting, recording, and sound applications where a stand-mounted microphone with a classic look is desirable. What type of polar pattern does the 55SH Series II have? A cardioid (unidirectional) polar pickup pattern is employed to minimize sound pickup from the rear of the microphone. This allows the Model 55SH Series II to be used in close proximity to loudspeakers without creating feedback problems, and it can perform under adverse acoustic conditions where omnidirectional microphones cannot.
