The SM48 unidirectional dynamic microphone is a great performance microphone. It maintains a true cardioid pattern throughoutits frequency range, ensuring high gain before feedback and rejection of off-axis sound. The tailored frequency response is ideal for lead vocals, backup vocals, and spoken word applications. A presence rise brightens mid-range performance, and a low frequency roll off controls proximity effect. The SM48 includes a shock-mounted cartridge, a steel mesh grille, and an integral ,pop , filter. Cardioid pickup pattern rejects off-axis sound and provides superior gain before feedback Frequency response tailored for vocals, with brightened mid-range and bass rolloff to control proximity effect Shock-mounted cartridge for exceptional ruggedness and reduced handling noise Built-in ,pop, filter that reduces explosive breath sounds and wind noise Supplied stand adapter and carrying/storage bag Lockable On/Off switch (Model SM48S only) Legendary Shure quality and ruggedness Type Dynamic Frequency Response 55 to 14000 Hz Polar Pattern Cardioid (unidirectional)-rotationally symmetrical about microphone axis, uniform with frequency Impedance Microphone rating impedance is 150 ohms (270 ohms actual) for connection to microphone inputs rated at 19 to 300 ohms Output Level (at 1000 Hz) Open Circuit Voltage: * -57.5 dBV/Pa (1.3 mV) *1 Pa = 94 dB SPL Connector XLR professional audio Polarity Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3.
