Models SM48 and SM48S User Guide 2006, Shure Incorporated 27C2699 (Rev. 6) Printed in U.S.A. MODELS SM48 AND SM48S UNIDIRECTIONAL DYNAMIC MICROPHONES Shure Models SM48 and SM48S unidirectional dynamic microphones are designed for professional sound reinforcement, studio recording, and broadcasting applications. They maintain a true cardioid pattern throughout their frequency range, ensuring high gain before feedback and rejection of off-axis sound. The tailored frequency response is ideal for vocals. A presence rise brightens mid-range performance, and a low frequency rolloff controls proximity effect. Both models include a shock mounted cartridge, a steel mesh grille, and an integral “pop” filter. The SM48S also includes a lockable On/ Off switch. Each microphone is supplied with an adjustable stand adapter and a zippered carrying/storage bag. Cables are available separately. FEATURES 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 (SM48S only) Legendary Shure quality and ruggedness VARIATIONS SM48 SM48S (with lockable On/Off switch) SPECIFICATIONS Type Dynamic Frequency Response 55 to 14,000 Hz (see Figure 1) Polar Pattern Cardioid (unidirectional) rotationally symmetrical about microphone axis, uniform with frequency (see Figure 2) Impedance Microphone rating impedance is 150 (270 actual) for connection to microphone inputs rated at 19 to 300 Output Level (at 1,000 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.
