Vocal microphone delivers a tailored response for a warm, natural sound. It features a cardioid polar pattern for maximum isolation, minimal off-axis tone coloration, a 3-stage pop filter to minimize breath noise, and a break-resistant stand adapter. Excellent for touring professionals, the BETA87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection. Vocalists who use personal monitor systems such as Shure PSM will appreciate how effectively the BETA 87C rejects ambient sound from the rear of the microphone. The Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection. The Shure Beta 87C vocal microphone. The BETA 87C is an excellent choice for professional studio recording, yet it is built to withstand the rigors of touring. It maintains its performance characteristics even at sound pressure levels as high as 139 dB SPL. Plus, the cartridge is protected by a proven shock mount system. A hardened steel mesh grille with a built-in pop filter provides added protection. Frequency response. Polar pattern. KEY FEATURES * Smooth, wide frequency response with slight presence rise * Uniform cardioid polar pattern for maximum isolation * Minimum off-axis tone coloration * Low-frequency roll-off compensates for proximity effect * Three-stage pop filter minimizes breath pop and noise * Break-resistant stand adapter SPECIFICATIONS * Transducer Type: Condenser (electret bias) * Frequency Response: 50 to 20,000 Hz * Polar Pattern: Cardioid * Output Impedance: Rated at 150 ohms (100 Ohms actual +/- 20%); Recommended minimum load impedance: 800 ohms * Sensitivity (at 1,000 Hz): Open Circuit Voltage: -51 dBV/Pa (2 mV); (1 Pa = 94 dB SPL) * Output Clipping Level: 1000 Ohm Load at 1,000 Hz: -6 dBV (0.5 V) * Maximum SPL: 139 dB at 1,000 Hz (0.25% THD, 1000 Ohm load) * Self-Noise: 22 dB typical, A-weighted; 24 dB typical, weighted per DIN 45 405 (equivalent sound pressure level; measured with true rms voltmeter) * Dynamic Range: 117 dB (maximum SPL to A-weighted noise level) * Hum Sensitivity: -5 dB equivalent SPL, maximum, in a 1 mOe field (60 Hz) * Signal-to-Noise Ratio: 72 dB at 94 dB SPL (IEC 651) -- *S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted. * Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of the output connector. * Power: Phantom Supply Requirement: 11 to 52 Vdc, positive at both pins 2 and 3 * Connector: Three-pin (XLR) professional audio * Case: Aluminum construction with painted blue metallic finish, and hardened steel grille with nickel satin chrome plating * Weight: 7.6 ounces FROM THE MANUFACTURER The Beta 87A has consistently been a top choice of performers and audio technicians around the world due to its superb accuracy and detail, and rich vocal production. This long-standing favorite now incorporates a cardioid polar pattern and has been named the Beta 87C TM. Developed in response to professional demands associated with the use of personal monitoring devices like the Shure PSM ® Series, Shure's new Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The uniform cardioid polar pattern of the Beta 87C enables users to effectively reject ambient noise arriving at the rear of the microphone, an attribute that will be especially appealing to users of personal monitors and others who frequently experience undesirable sounds bleeding into their mixes. Other features include: * Smooth, wide frequency response with slight presence rise * Uniform cardioid polar pattern for maximum isolation * Minimal off-axis tone coloration * Low-frequency roll-off compensates for proximity effect * Three-stage pop filter minimizes breath pop and noise * Break-resistant stand adapter * Frequency response: 50 to 20,000 HzVocal microphone delivers a tailored response for a warm, natural sound.
