Pearl's linear capsule has more than twice the surface area of large-diameter round capsules. This gives excellent signal-to-noise ratio and a near resonance-free frequency response. The ELM-A's speciality is its polar pattern that is a normal cardioid horizontally and much narrower vertically.
The ELM-A has two separate outputs via a 5 pin XLR connector. Both outputs deliver independent cardioids, one from each membrane of the dual membrane capsule, i.e. "Back to Back" output or 180 degrees stereo. Both sides can be used simultaneously or independently. When the ELM-A is connected to two inputs at the console/DAW, an omni, figure-of-eight or cardioid pattern can be obtained by using the pan pots and phase shifting of one channel.
The ELM-A is finished in piano black ED lacquer with a white logo, ring and engraved model number.
